The limit for arsenic is indicated in the individual monographs in terms of ppm, i.e., the parts of arsenic, As, per million parts (by weight) of the substance under examination. All reagents used for the test should have as low a content of arsenic as possible. diet for weight loss in 7 days pdf Arsenic (III) was determined in an ammonium citrate buffer solution, and the total inorganic arsenic determined in tartaric acid, with arsenic (V) determined by difference. The detection limit was 0.16 μg L −1 for arsenic (III) and 0.36 μg L −1 for inorganic arsenic .
