Welcome to 2012 everyone! This year, we are continuing to expand for more capacity by upgrading our equipments and adding more highly experienced analytical chemists to tackle nonGMP (R&D) and cGMP work. We have also launched a new initiative to help reduce unforeseen testing delays and OOS's due to incomplete methodology or sample information; as a result we will be able to offer reduced turn-around times and pricing for routine sample testing with qualfied HPLC or UPLC methods.<br />
<br />
<strong style="margin: 0px; padding: 0px;">Waters ACQUITY UPLC H-Class</strong><br />
We just acquired our new UPLC to offer optimization of legacy HPLC methods that have extensive run times. Additionally, we are developing our library for amino acid and peptide analysis in both pure form as well as complex sports nutrition and performance products. While a baseline of experience is critical, efficient method development and/or qualification and validation are critical to long term brand success.<br />
<br />
<strong style="margin: 0px; padding: 0px;">Composite Reference Botanicals (CRBs)</strong><br />
In 2009 we launched our line of Composite Reference Botanicals for customers developing their own in-house Identity Testing capabilities by HPTLC on incoming raw materials. With approximately 150 CRBs comprised of botanical specimens that have been verified dating back nearly a decade or more, including many to vouchered specimens, we're proud to say that we have the largest offering of reference botanicals for Ingredient Identity purposes available commercially. For a current list, please contact us today!<br />
<br />
In addition to Identity Testing, many clients have bought our CRB's to assist in the following ways:<br />
<br />
<em style="margin: 0px; padding: 0px;">Product Formulation</em><br />
- Utilzing a CRB as a verified ingredient to start product development and/or improve upon their product formulation.<br />
<br />
<em style="margin: 0px; padding: 0px;">Process Development</em><br />
- CRBs are whole botanicals, but enable customers to evaluate new extraction procedures/techniques with identify confirmed whole raw materials to generate a qualitative profile whether by FTIR, HPTLC or even HPLC.<br />
<br />
<em style="margin: 0px; padding: 0px;">Investigations</em><br />
- CRBs with their specific phytochemical profiles can give insight to potential Supply Chain issues as well as limitations or gaps in testing methodology.</div>

Intellectual Property comes in all shapes and sizes, and sometimes companies don't know they even have any IP to protect other than a copyright. At an economic time when companies must adapt their position to best leverage their brand and grow sales, we are finding out quite often that the back door is left wide open.<br style="margin: 0px; padding: 0px;" /> <br style="margin: 0px; padding: 0px;" />Case in point, a small company selected a particular Contract Manufacturing Organization (CMO) vendor that has an industry recognized seal of GMP compliance and a recognized brand name. After working with the CMO to get the ideal formulation and manufacturing the first several production batches, the company opted for a third-party investigative analysis of their finished product due to a small discrepancy. It was then that the company realized "things" were not what they seemed i.e. their formulation had been changed without their prior approval. Furthermore, because the CMO partner didn't charge the company for development on the final formulation, they would not support the investigation or disclose any details of the ingredients or testing of the product because it was "proprietary" ...to the CMO! <br style="margin: 0px; padding: 0px;" /> <br style="margin: 0px; padding: 0px;" />In another case, a start-up company engaged in development of Botanical Drug products and related IP sought out a laboratory to contract the isolation and characterization of some new compounds. The contract lab they selected offered the company to do the work at a great rate including delivery of nearly twice the amount of the desired compounds. With compounds in hand, the company went on to the next stages of developing their product. They did not realize the lab they contracted also had their own business interest in the compounds. Because of opting to conduct the work at a lower price compared to some other bids received, they inadvertently waived the rights to the isolation and purification processes, the characterization IP and ultimately the exclusive use of the isolated compounds because these were outside of the Scope of Work. By the time the package was submitted, the various compounds were already on the open market. <br style="margin: 0px; padding: 0px;" /><br style="margin: 0px; padding: 0px;" />To help understand, identify and protect your IP, the folks at <a href="http://www.ingredientidentity.com/" style="margin: 0px; padding: 0px;">Ingredient Identity</a> can help!</div>

<div class="newscontent" style="color: #495f7e; font-family: Arial, Helvetica, sans-serif; font-size: 12px; font-style: normal; font-weight: normal; line-height: 16px; margin: 0px; padding: 0px 0px 10px; text-align: justify; vertical-align: top;">
A Quality Agreement is a legally binding document, which outlines specific quality parameters for a service to be rendered and identifies the responsible party (or parties) obligated to uphold those parameters under the Service Agreement. In lamens terms, its the upfront contract you put in place with your manufacturer in addition to the Service Agreement, to make a product in accordance with your standards and current regulations. A Quality Agreement defines all the aspects of a service or product relating to how identity, purity/potency, quality and overall safety of a given product is manufactured and maintained. Whereas the Service Agreement typically defines the legalese and scope of a project as well as deliverables for a set price, it does not usually address "HOW" the partner will accomplish the service; hence, the Quality Agreement.<br />
<br />
A well drafted Quality Agreement offers you protection should your contract manufacturer not uphold the terms therein. For example, if an agreed upon quality testing regimen is not followed or disregarded altogether, you may very well have legal leverage to change certain terms or dismiss the Service Agreement altogether. Same thing applies if your contract manufacturer is found operating not under cGMP compliance or changes raw material suppliers without your permission or appropriate qualifiction. Whether the CMO has an in-house laboratory or contracts with a third-party lab, you should request and have access to all testing records for your raw materials and your finished product on file. </div>

There are numerous reasons why an HPLC method might not work for your product, but are you getting the run around as to what the real reasons are, and more importantly what the right solution is? Moreover, how can you identify the right solution for the least amount of money?<br style="margin: 0px; padding: 0px;" /><br style="margin: 0px; padding: 0px;" />A strategic understanding of the appropriateness of method qualification should be considered fundamental to any Quality System. All too often, we are engaged in last minute troubleshooting for customers who had little or no early enough investment into the quality management of their products from an analytical perspective. Often, the mindset remains on finding a quick and dirty formulation followed by aggressive marketing of such products without qualifying the supply chain properly or ensuring analytical methods are in place. The resulting production delays, development fees and other costs relating to release testing, cGMP compliance and lastly mitigation of FTC or civil litigation can scale up to be insurmountable and cost-prohibitive in a very short period of time, if critical steps were not taken in the beginning. <br style="margin: 0px; padding: 0px;" /><br style="margin: 0px; padding: 0px;" /> For more information on how to qualify an HPLC method or to determine if method development is required for your product, give us a call today!</div>

Yes, it's possible and more affordable than other more costly analytical techniques such as GC or GCMS!<br style="margin: 0px; padding: 0px;" /><br style="margin: 0px; padding: 0px;" />We've expanded our portfolio of Identity Testing methodologies for more essential and botanical oils used in Food Supplements, Cosmeceuticals and Aromatherapies. For comprehensive ID work of either pure oil ingredients or complex blends, we can profile the sample to confirm identity and compliance with cGMP's.</div>

Misidentification of the collected plant and corruption of purity of the raw materials can easily occur when other species or contaminates find their way mixed into the ingredients. Extraneous ingredients such as starch, maltodextrin, sawdust, chemicals, other botanicals, and even mycotoxins and deadly allergens, have found their way into products in the past, causing potentially significant health risks.<br /><br />As part of Alkemists Pharmaceuticals’ Premium Partner Random Analysis Program, dietary supplements are acquired via ‘secret shopping’ retail locations that are randomly selected throughout the Untied States. Products are then scrutinized for identity, purity and authentication of ingredients. In this case, the ingredient Hoodia, was inspected, a dietary ingredient that has suffered much adulteration in the past.<br /><br />Alkemists Pharmaceuticals conducts their Premium Partner Random Analysis quarterly for companies that have volunteered for inclusion. Utilizing their Analytical Triad Analysis, Alkemists conducts tests whereby systematic identification and detection of botanicals & their marker compounds are evaluated for quality control. The most updated and sophisticated combination of technologies are employed, including Digital Photo-Microscopy (DPM), High Performance Thin-Layer Chromatography (HPTLC) and/or High Performance Liquid Chromatography (HPLC).<br /><br />Although natural ingredient testing seems fairly straightforward, analyzing individual components of a finished product manufactured within a complex matrix of food based materials it is no simple task. Highly complex materials, such as botanicals, vary significantly by influences of season, growing conditions, location and age. In addition, influencers like shelf-life of manufactured products introduce ingredient degradation possibilities. Not only must the core ingredients be tested and considered, but how additional influencers may react, corrupt or negate the desired therapeutic effects must be evaluated as well.<br /><br /> “I am happy to report positive news about Hoodia supplements again. As the Hoodia industry emerges from the wake of previous challenges, information of this sort is invaluable,” stated Elan Sudberg, Chief Operations Officer and Lab Manager of Alkemists Pharmaceuticals. “The voluntary random testing program enables companies, whose products are ready to be scrutinized under the microscope, both literally and figuratively, to showcase their quality.<br /><br />Third party certification of ingredient purity shows consumers that the products that are purchasing come from a company who has a commitment to quality and performance, and the confidence to go the extra distance to prove it. These companies are leading the way in this industry and are differentiating themselves in the marketplace by their voluntary participation in this program. They are raising the bar by providing the extra assurance needed to garner trust and confidence in the purity of natural ingredients that end up in the bodies of their friends, their neighbors and their loved ones. “<br /><br />"With so many adulterated Hoodia products in the market, Alkemists is providing a desperately needed service to identify those Hoodia products that can be trusted to contain what's promised on the bottle," said Mike Adams, a consumer health advocate and independent journalist at NewsTarget.com. "Knowing which Hoodia products can be trusted means that consumers now have several trusted brands to choose from. Genuine Hoodia is a valuable plant-based supplement for appetite control, but counterfeit Hoodia is simply a waste of money. Now consumers can tell the difference between the two."<a href="http://www.npicenter.com/anm/templates/newsATemp.aspx?articleid=19689&zoneid=2"><br /><br />http://www.npicenter.com/anm/templates/newsATemp.aspx?articleid=19689&zoneid=2</a><br /><br /><a href="http://alkemist.com/Program_Outsourcing.htm">http://alkemist.com/Program_Outsourcing.htm</a>Alkemists Labshttp://www.blogger.com/profile/05998262126977570722noreply@blogger.com0tag:blogger.com,1999:blog-4866569568376042004.post-49003634034297142462008-11-18T12:45:00.000-08:002008-11-18T13:40:59.165-08:00Digitalis Contamination Case Study<meta name="ProgId" content="PowerPoint.Slide"><meta name="Generator" content="Microsoft PowerPoint 11"><!--[if !mso]> <style> v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} p\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} v\:textbox {display:none;} </style> <![endif]--><title>Slide 6</title><meta name="Description" content="11/18/2008"><!--[if !ppt]--><style> .O {color:black;

And by matrix I'm refering to the composition of the sample, which itself and introduce many challenges to any highly trained analyst.<br /><br />So though we have a huge library and database of botanical identity methods (over 1000 now), we're constantly optimizing such methods for our clients depending on what they send us. For the whole, untouched/unextracted botanicals, analysis tends to be much simpler and consistent, but then again we get herbs and botanicals from around the world, so it's always exciting to work on new challenges. Much of what this goes to help validate is a base of experience and dated expertise that we leverage to tackle time-sensitive projects or other test requests. Most importantly, the degree of assurance and quality of work offered to Clients is what keeps them coming back. Nonetheless, the best methods for botanical identity testing are the one's developed specific to a Clients product/ingredient and presuming that the upfront investment in Development is worthwhile to them, potential downstream issues relating to product variability, ingredient sourcing, lab testing, or meeting label claims are almost certainly avoidable.<br /><br />For more information check us out at <a href="http://www.alkemist.com/">http://www.alkemist.com</a>Alkemists Labshttp://www.blogger.com/profile/05998262126977570722noreply@blogger.com1
