Shimadzu Corporation, with the business philosophy of "achieving the health of human beings and the earth", has launched the "Microwave Digestion of Cold Atoms" to protect the safety of dairy products by referring to the standard GB / T 5009.17-2003 "Determination of Total Mercury and Organic Mercury in Food". Atomic absorption spectrophotometric determination of mercury in milk powder "detection solution. The method is simple and fast to operate, with high accuracy and precision, and the mercury-containing waste liquid is absorbed by the potassium permanganate absorption liquid, and is harmlessly treated, which is an effective method for measuring the mercury content of dairy products and other various foods .
