What is the reagent, Sodium Tartrate Dihydrate like and when is it needed? [Moisture Analyzers] [MS/MX/MF/ML]

Sodium Tartrate Dihydrate is suitable for testing a moisture analyzer itself since its moisture content rate is deemed theoretically. Sodium Tartrate Dihydrate is Sodium Tartrate when chemically bonded to two water molecules or crystal water and becomes Sodium Tartrate again by releasing the water molecules when heated. Its moisture content rate is the ratio of the two water molecules, that is 36.031/230.082=15.66%. This sample is a standard accessory of MS/MX and optional accessory of MF/ML (30g x 12pcs).
