Food Safety Testing Equipment for Heavy Metal analysis in Fruit vegetable
Detection principle
Organic phosphorus and carbamate pesticides is currently the largest use of pesticides, and more is prohibited in the use of fruits, vegetables. This type of pesticide in the body can be combined with acetylcholinesterase (Ache), and difficult to separate, that Ache activity is inhibited, resulting in nerve conduction of acetylcholine can not be hydrolyzed and accumulated, nervous excitement, symptoms of poisoning and even death. Based on the principle of enzyme inhibition of the enzyme inhibition rate method, the detection principle can be simply expressed as follows: the use of a sensitive enzyme source prepared by the preparation of butyrylcholinesterase as a detection reagent, according to the degree of activity of butyrylcholinesterase To determine the residual pesticide in fruit and vegetable samples.Feature
1. Test items: Pesticide residues, formaldehyde, sulfur dioxide, sodium bicarbonate, methanol, nitrate, nitrite, hydrogen peroxide, organic phosphorus, protein, potassium sorbate, borax, molybdenum, lead, chromium, cadmium, mercury, arsenic and other toxic and harmful substances.
2. 5-inch LCD capacitive touch screen; Human computer interaction is simple and convenient;
3. Number of channels: 10 channels, which not only ensures high test efficiency, but also ensures the accuracy and reliability of test results;
4. Instrument operation simulation: single machine, online.
5. The instrument has its own intelligent Chinese input function, which is selected by users.
6. The built-in clock can display the date (month, month, day) and week in real time, which is convenient for the operator to control the time.
7. Query function, which can be used to query items, dates and numbers by single condition or by combination of multiple conditions; Read the test data directly.
8. Built in thermal micro printer, which can print test report according to test item, date or number at any time.
9. The instrument has the calibration function. The consistency calibration between channels is completed before leaving the factory. The absorbance resolution of the instrument is 0.001.
10. Sample information: it must include sample number, sample name, test results, judgment results and other information
11.The instrument has an information prompt box for real-time operation steps and error prompt.Main technical parameters :
