Due to the large number of samples and their nature, dispatch might need up to two days. Please note that samples 60 and 61 are not currently within the scope of LGC Standards' accreditation. QFCS (Quality in Food Chemistry) Scheme 2016 Sample 771: The vitamin analytes, previously part of sample 770, have been moved to a separate sample, available in two rounds (FC242 June and FC248 December) New trial sample 787: Nitrate analysis in green leaf products is available in round FC240 April New trial sample 788: Acrylamide in snacks available in round FC240 April New trial sample 789: Toxic metals (As, Cd, Pb) in brown rice available in round FC240 April We have increased the number of rounds to 6. In conjunction with our QMAS Meat and Fish scheme, we are now offering food chemistry samples every month. We aim to expand our food chemistry offering further throughout 2016 with the introduction of additional test materials, and we will contact you further as soon as more information is available. QGS (Quality in Gelatine) Scheme 2016 Two new trial samples for the 2016: 605 for the enumeration of mesophilic anaerobic spores 606 for physicochemical testing of gelatine. Participants can analyse the sample for ash, gel strength, isoelectric point, moisture, ph and viscosity. Both samples are available in both rounds, GL241 (May) and GL246 (October). Please note that sample 606 is not currently within the scope of our accreditation Page 1 of 6
QMAS (Quality in Meat and Fish Analysis) Scheme 2016 New trial sample, 753, in round MT239 (March) for the detection of Aeromonas species. Number of rounds available for sample 748 (Histamine; Total volatile nitrogen; Trimethylamine) increased to 3 due to high demand from participants. Rounds for samples 741 (trace elements in shellfish) and 742 (trace elements in fish) alternated, to spread the analysis for labs who take all four available rounds. Sample 751 (fish authenticity - confirmation of cod in fish) has been discontinued. If you participated in this sample you may wish to order sample 752, for fish species identification, which is available in round MT245 (September). Increased the number of samples provided in 752 to 4 x 20g samples enabling a wider range of species to be included. Increased the number of Chemistry rounds in the QMAS scheme to 6. When combined with our QFCS Food Chemistry scheme, food chemistry samples are now available every month. We aim to expand our meat chemistry offering further throughout 2016 with the introduction of additional test materials, and we will contact you further as soon as more information is available. QMS (Quality in Microbiology) Scheme 2016 Incorporated samples previously available in the QMIS (Microbiology Investigation Competency Assessment) PT Scheme into QMS as follows: Sample 33: Identification of unknown organism (non-pathogen). A routine organism for identification. Participants can report up to 10 basic tests, such as gram stain, basic biochemical tests, cell morphology, motility, and also a final identification. All tests will be assessed as well as the final identification. No scenario is given, as the choice of method for performing the final identification must be based upon the results achieved from the basic tests carried out. Sample 34: Salmonella identification. A strain of Salmonella will be provided for culture and serological testing. Sample 35: Counting of colonies and calculation of number of microorganisms paper exercise. A photograph and document will be provided for two checks to be carried out. The first is enumeration of specific organisms from an identical image of a culture plate provided to all participants. This will test basic colony identification and counting techniques. The second is a simple statement of the number of colonies isolated on a given dilution plate, with the original weight of sample; participants must calculate the level of the stated organism in the original sample. Whilst this sounds very easy, our experience is that calculation error is one of the most common reasons for unsatisfactory performance in a PT scheme. ENVIRONMENTAL and WATER PT Schemes HYGIENE (Environmental Hygiene Monitoring) Scheme 2016 Addition of two new TRIAL samples for the 2016 scheme year, both in round HY239 March: Sample 4 Hygiene testing using dipslides for Total viable count and Coliforms enumeration Sample 5 Surface testing for ATP Page 2 of 6
QWAS (Quality in Water Analysis) Scheme 2016 Incorporation of samples previously available in the QMIS (Microbiology Investigation Competency Assessment) PT Scheme into QWAS as follows: Sample 426: Identification of unknown organism (non-pathogen). A routine organism for identification. Participants can report up to 10 basic tests, such as gram stain, basic biochemical tests, cell morphology, motility, and also a final identification. All tests will be assessed as well as the final identification. No scenario is given, as the choice of method for performing the final identification must be based upon the results achieved from the basic tests carried out. Sample 427: Counting of colonies and calculation of number of microorganisms paper exercise. A photograph and document will be provided for two checks to be carried out. The first is enumeration of specific organisms from an identical image of a culture plate provided to all participants. This will test basic colony identification and counting techniques. The second is a simple statement of the number of colonies isolated on a given dilution plate, with the original weight of sample; participants must calculate the level of the stated organism in the original sample. Whilst this sounds very easy, our experience is that calculation error is one of the most common reasons for unsatisfactory performance in a PT scheme. BEVERAGE PT Schemes BAPS (Brewing Analytes) Scheme 2016 We continue to offer sample 7, introduced as a trial in 2016, in four rounds during 2016. This sample is for the chemical analysis for alcohol free/low alcohol beer. Participant numbers for sample 6, chemical analysis of brewing liquor and effluent simulant solution, are such that it is no longer sustainable within the scheme. This sample has therefore been removed for 2016. DAPS (Alcoholic Drinks) Scheme 2016 A new sample for Esters, sample B5, (run as a trial in October 2015) has been added to the scheme with two rounds available in 2016; DP085 April and DP087 October. Sample B1, rounddp085 will contain Cask extractives for testing MAPS (Malt Analytes) Scheme 2016 Sample 4, the specialised malt sample, has been separated for clarity into two samples: 4A for black malt and 4B for crystal malt.
