Inorganic salt (nitrite)
Identity: Sodium nitrite
IUPAC name: sodium nitrite
Method for the $250 identity, purity and quantity test: ICP-MS metal content, against a reference standard, with results in 3 to 5 business days.
The USP monograph covers identity by sodium and nitrite chemical tests and ion chromatography retention time, assay by ion chromatography with suppressed conductivity detection, aluminum, iron, selenium, calcium and potassium limits by ICP-MS, sodium nitrate by ion chromatography, carbonate and non-purgeable organic content by total organic carbon, sulfate and chloride limit tests, bacterial endotoxins, microbial enumeration, pH, insoluble matter, and loss on drying. Full testing to the USP Sodium Nitrite monograph is available and quoted.
Chromatographic purity and mg per unit by the method matched to the compound, identity against a reference standard. 1 unit.

No. The $250 test covers identity, purity and quantity by ICP-MS for sodium content. Full testing to the USP Sodium Nitrite monograph is available and quoted.
Nitrite is a small inorganic anion with no organic structure, so it is measured by ion chromatography rather than reverse-phase HPLC. Sodium itself is measured by ICP-MS.
Sodium nitrite slowly oxidizes to sodium nitrate in air and picks up moisture. Nitrate content and water are the usual reasons for a low nitrite assay.
