1.Microorganisms:Microbiology laboratory should be laid out in accordance with the requirements of the specified standards of biological laboratory instruments and equipment . The necessary equipment includes clean workbench , incubator , high temperature sterilizing oven , electric furnace ,etc. Other devices are configured according to the specific test items.
2.Additives and harmful elements : Some of the projects can use chemical methods. But to meet with the requirements of the current national standards of food hygiene , you should purchase gas phase chromatograph-hydrogen flame detector , liquid phase chromatograph-ultroviolet/visible light detector, atomic absorption spectrometer-graphite furnace detector,atomic fluorescence spectrometer,etc.
3.Residues pesticides:Gas chromatography is needed for detecting residual pesticides.The laboratory should be equipped with electron capture detector(ECD), if you want to detect organic chlorine pesticide.Nitrogen-phosphorus detector(NPD) or flame photometric detector(FPD) should be equipped to detect organic phosphorus pesticide.Nowadays, there are more and more pesticide-detecting items to be done.In order to improve the generality , purchasing capillary column split-splitless injection port and installing capillary column are suggested.Gas chromatograph-mass spectrometer can be purcahsed for export food proceeding enterprises to control the quality of raw materials and products.
4.Ainimal residues:As to detection of veterinary drug residues, there are few detecing items and more batches,so it is suggested that a set of ELISA Reader should be purchased and configured.For export food enterprises that have a certain scale,liquid chromatography-tandem mass spectrometer is a better choice.
