SODIUM ARSENATE DIBASIC HEPTAHYDRATE (C005B-003363)

General description

Sodium arsenate dibasic heptahydrate (As(V)) is an arsenic compound.

Application

Sodium arsenate dibasic heptahydrate may be used as a reference standard for the quantification of arsenic compounds in rice- and seafood-based samples by ion chromatography-inductively coupled plasma/ mass spectrometry. The samples for analysis were prepared by ultrasonic-assisted enzymatic extraction (UAEE).
