What equipment is needed for vegetable testing

Twenty-three indicators are used to test the hygienic quality of vegetable products. They are fluorine, arsenic, mercury, cadmium, lead, chromium, HCH, DDT, phosphorus, methamidophos, parathion, phoxim, malathion, fenthion, oxolin, dichlorvos, acephate, oxolin, Deltamethrin, cyhalothrin, chlorothalonil, carbendazim, nitrite.

1. Commonly used vegetable testing instruments and equipments are as follows

Food Safety Tester: Routinely detect pesticide residues, sulfur dioxide, formaldehyde, dosimeter vs geiger counter nitrite, sodium chloride, borax, alum and nitrate in vegetables, with a total number of not less than 110 testing items

2. Food heavy metal detector: detect cadmium, lead, mercury, arsenic, cadmium, aluminum, cobalt and other heavy metals.

3. Pesticide residue analysis detector: mainly can be used for a variety of vegetables, fruits, tea, food, water and soil in the organophosphorus and carbamate pesticides for rapid detection.

4. Solid phase extraction is mainly used to analyze organic matter in water, such as polycyclic aromatic hydrocarbons and polychlorinated biphenyls, fruits, vegetables and herbicide residues,tds meteras well as the analysis of antibiotics.

5. Nitrogen Blower: Adopting the blowing and trapping technology, meanwhile, the sample can be heated with temperature control, and inert gases such as nitrogen can be blown to the surface of the sample rapidly, controllably and continuously to realize the rapid anaerobic concentration of the sample solution, which is used for food safety and pesticide residue detection.

6. Gas Chromatography (GC): Determination of oxolinic acid, organophosphorus chemicals, phosphorus sulfide, methamidophos and other indicators.

7. GC-MS: Pesticide residue detection.

8.Ion Rapid Chromatography: Ion exchange chromatography to measure nitrite in vegetables.

9.Atomic fluorescence spectrometer: used to analyze arsenic, mercury, selenium, tin, lead, bismuth, antimony, tellurium, GE, cyclodextrins, zinc and gold in the sample

10.Inductively coupled plasma emission spectrometer: to determine trace elements in different substances (dissolved in nitric acid,geiger counter radiation detector hydrochloric acid, hydrofluoric acid, etc.). .
