PHYTAS - Phytochemical TestingAssurance SchemePHYTAS has been developed in response todemands from the phytochemical industry.In recent times there has been a huge amountof media attention and popular interest inmedicinal plants and the chemicals they contain.These plant materials are highly valued for therole they can potentially play in promoting andsustaining human health. Plants have evolvedto produce an array of secondary compounds,many of which have been used in traditionalmedicines and remedies for hundreds of years.The most common classes of ‘active’ compoundfound in medicinal plants are alkaloids,terpenoids, phenols and glycosides, though therange of compounds is by no means limited tothese four classes. As extracts of living matter,the quality and potency of botanical products issubject to variation, giving rise to uncertaintyamongst consumers, analysts and regulatorsalike.The analysis of such a wide range ofcompounds, in what is by definition an incrediblydiverse range of matrices, is not alwaysstraightforward and there is little standardisationof methodologies from laboratory to laboratory.One of the major concerns in a relatively newand broad field of analysis is this lack ofstandardised methods and even definition ofthe ‘required’ components for analysis.<strong>Proficiency</strong> <strong>testing</strong> is an important tool in theimprovement of analytical performance inscientific disciplines such as this and bystandardising the quality of analysis, one ofthe variables is removed – helping to achieveconsistency in the quality of the finishedproduct for the consumer.The full range and availability of test materialsin PHYTAS is determined on an annual basisand further details can be found in PHYTASapplication form and scheme description.OtherPT schemesTest materialBotanicalAnalytesIdentification and quantificationof a range of active ingredients.Note: Test materials and analytes may be added or removed, pleasesee current application form.

QMIS - Microbiology investigation schemeThe Quality in Microbiology InvestigationScheme (QMIS) is designed to work alongsidethe QMS scheme (see page 18).QMIS differs from the normal schemes in thatthe microbiologist must carry out specifiedlaboratory techniques and apply furtherinvestigative measures in order to identify anunknown organism provided for analysis. Ittherefore assesses the ability to carry outfundamental microbiological techniques, andfrom the results of these, determine the finalidentity of the isolate.Each test material is provided with briefinformation about its origin, along with narrativedetails, from which the microbiologist mustdeduce the necessary tests (in addition to thoseprescribed in the accompanying information,such as Gram stain, catalase, oxidase, etc.)required to achieve the correct identificationof the organism.Test materialFood and WaterAnalytesFood:Unknown pathogen foridentification with scenario.Food:Unknown routine organism foridentification with scenario.Water:Unknown isolate for identificationwith scenario.QMIS organisms are selected from ourcomprehensive range of microorganisms ofrelevance to food and water analysis and arepresented in a lyophilised format to includepathogens, indicator organisms and spoilageorganisms.Note: Test materials and analytes may be added or removed, pleasesee current application form.OtherPT schemesThe full range and availability of test materialsin QMIS is determined on an annual basis andfurther details can be found in the QMISapplication form and scheme description.Email: customerservices@lgcpt.comWebsite: www.lgcpt.com45
