Food formaldehyde rapid detector model: XOD3-MR-550B ◠Instrument use is mainly used in the food safety field to quickly detect aquatic products, water-based foods, rice, noodles, soy products, etc. artificially added formaldehyde (formalin) or formaldehyde Sodium bisulfate (white block) can also be used to determine the formaldehyde content of other liquid and solid samples. -------------------------------------------------- -------------------------------------------◠Detection principle under specific conditions The formaldehyde is condensed with AHMT (4-amino-3- hydrazin-5-mercapto-1,2,4-triammonia) and then oxidized to form a purple-red compound whose color depth is proportional to the formaldehyde content. The absorbance of the compound is measured, and the concentration of formaldehyde in the sample to be tested is automatically calculated and printed. Proteins, fats, starches, amino acids, sugars, acetaldehyde, propionaldehyde, benzaldehyde, methanol, ethanol, isopropanol, ethyl acetate, nitrogen dioxide, sulfur dioxide and the like have no interference with the determination method.
