Electrochemical operation process of rice heavy metal detector

2018-04-28 06:24:19

The heavy metal rapid detector and its supporting detection electronics can quickly determine the content of various heavy metals in various grains and their products, feed, feed raw materials and Chinese medicinal materials. The operation is fast and simple, and the results are accurate and reliable.

Tools/Materials
1

Electrochemical heavy metal rapid detector

2

Electrodes for rapid detection of heavy metals

3

Pre-treatment equipment: mixing instrument, oscillator

Methods/Steps
1

This page is based on experience

2

Add 5mL reagent A and fully oscillate the vortex for 2min. Add 5mL reagent A and fully oscillate the vortex for 2min.

3

Take out the wire mesh electrode, insert it into the electrode plug, place the reaction tank in the socket of the stirring table, then take 900ul reagent B and add it to the reaction tank, fully press down the electrode plug, and make the working area of the wire mesh electrode completely immersed in the solution.

4

Select the test sample type and item, click the "activation" button to start activation, after activation, take 200ul centrifuge supernatant, add it from the back of the wire mesh electrode, click the "detection" button of the instrument, after the test is completed, the data displayed on the interface of the instrument is the content of heavy metals lead and cadmium in the sample

Matters needing attention
1

Do not touch the black detection area of the screen printed electrode during the test

2

When the supernatant is added to the reaction pool after 200ul centrifugation, be careful to add it from the back of the wire mesh electrode, and do not add it from the front
