Application of Spectroscopic Colorimeter in Pesticide Industry

Pesticides can be used to prevent, eliminate or control diseases, insects, grasses and other harmful organisms that endanger agriculture and forestry, and to regulate the growth of plants and insects purposefully. The vegetables and fruits on the market that require bright colors and delicious taste all need the protection of pesticides to prevent them from being infested by pests. Pesticides have both advantages and disadvantages. They are good for plants, but they can cause safety hazards if eaten by mistake. Be careful when using them. And the pesticides in each batch will also have the problem of color difference, which will affect the efficacy of pesticides, which is also a headache for pesticide manufacturers. So what is the most useful color measurement? Of course, it belongs to the spectroscopic Colorimeter of the color spectrum.

Pesticides are in the form of granules, powders, thick liquids, etc., so we choose the desktop Spectrophotometer CS-800 of Color Spectrum. The opening of the CS-800 is upward, which is convenient for measuring samples in different states such as solid, granular, powder, and paste. Take liquid, powder, and granular pesticide samples as examples.

After the black-and-white calibration, use a needle to draw the liquid sample out of the bottle and place it into a circular cuvette (note: the cuvette needs to be cleaned to ensure accurate measurement), then place it into the measuring port of the instrument for measurement, and get the data.

The three samples were measured twice in a similar way, and the table was obtained.

The color spectrum Spectrophotometer is used to control the color of pesticides, and the operation is simple and easy. Color Spectrum's Spectrophotometer is super cost-effective, suitable for color difference control in different fields, and is the leader of domestic color difference measuring instruments! According to this analysis, the difference between the data measured twice for each sample is small, and the color difference is small. CS-800 can accurately measure the L, A, and B values ​​of samples with good repeatability, and can well control the color consistency of the same batch of pesticides, thereby reducing the influence of color difference on the efficacy of pesticides.
