Thissample is designed to test theability of laboratories to identifyorganic compounds via GCMSanalysis.Participants are provided with asolution containing ten organiccompounds. The test requires thatparticipants identify the tencompounds present. Resultsreturned will be identified assatisfactory or unsatisfactory.Participants are also providedwith a solvent blank.The choice of the ten organiccompounds is designed to avoidthe formation of reactionby-products.Six organic analytes are providedfor qualitative identification. Thissample is designed to test theability of laboratories to identifyorganic compounds via purge andtrap GCMS analysis.Participants are provided with asolution containing six organiccompounds. The test requires thatparticipants identify the sixcompounds present. Resultsreturned will be identified assatisfactory or unsatisfactory.Participants are also provided witha solvent blank.The choice of the six organiccompounds is designed to avoidthe formation of reactionby-products.Sample 25Qualitative Determination inClean WaterSample 26PFOS and PFOASample 27AOX in WastewaterSample 30Gross Alpha and Gross Betain Clean WaterSample 31Aqueous Tritium in Clean WaterSample 50EcotoxicologyThe intent of this sample is to testthe ability of laboratories to detectand identify an unknowncontaminant in surface/potablewaters. This sample is designed forlaboratories which may be involvedin investigating potentiallycontaminated potable or surfacewaters and tests both the extractionand identification stages ofinvestigations.Participants are provided with atwo litre water sample and one ormore ‘indicators’ of a potentialproblem, e.g. water is discolouredor has an oily sheen.Participants are asked to identifythe contaminating substance(s).Results returned will be identifiedas satisfactory or unsatisfactory.Perfluorooctanoic acid,Perflurooctanesulfonic acid.Adsorbable organically boundhalogens.Gross Alpha as 241 Americium,Gross Alpha as 239 Plutonium,Gross Beta as 137 Caesium,Gross Beta as 40 Potassium,Gross Beta as 90 Strontium.Aqueous Tritium.Daphnia magna 24hr EC50,Daphnia magna 48hr EC50,Freshwater algae growth inhibitiontest – biomass reduction(Pseudokirschneriella subcapitata),Marine algae growth inhibition test(Skeletonema costatum), 15 minuteluminescent bacteria IC50 tests,Other 30 minute luminescentbacteria IC50 tests, Oyster 24 hourembryo-larval development test(Crassostrea gigas), Tisbebattagliai 48 hour mortality test,Vibrio fischeri 30 minute IC50(ISO 11348-3), Vibrio fischeri30 minute IC50 (ISO 11348-2).Note: Test materials and analytes may be added or removed, pleasesee current application form.Water andenvironmentPT schemesSample 23Mineral Oil in WaterSample 24Oil and Grease in WaterTotal Hydrocarbons by GC Analysis,Total Hydrocarbons by GravimetricAnalysis, Total Hydrocarbons by IRAnalysis, Volume of sampleprovided.Total Oil and Grease,Volume of sample provided.Email: customerservices@lgcpt.comWebsite: www.lgcpt.com25
