Determination of sodium azide in the presence of proteins by high-performance liquid chromatography

Toxicological analysis of azide and cyanide for azide intoxications using gas chromatography

“…Accordingly, there is a growing relevance and importance to develop methods for the identification and quantification of azide. A few methods have been described in the literature for the determination of azide in biological matrices, [8][9][10][11][12][13][14][15][16][17] but not for the combined analysis of azide and cyanide using the same procedure. Several reports found elevated levels of cyanide in blood or plasma after azide ingestion.…”

Solid-phase extraction combined with dispersive liquid–liquid microextraction for the spectrophotometric determination of ultra-trace amounts of azide ion in water samples

“…The threshold limit value (TLV) for sodium azide was reported as 0.3 mg m À3 . 4,5 Different methods have been reported for the determination of azide ion, such as titrimetry, 6,7 high-performance liquid chromatography, [8][9][10] gas chromatography, 11 capillary electrophoresis, 12,13 ion chromatography, [14][15][16][17] amperometry, 18,19 electron paramagnetic resonance 20 and spectrophotometry. [21][22][23][24][25] Some of these methods are time-consuming and suffer from a lack of sensitivity.…”

Ion chromatography of azide in pharmaceutical protein samples with high chloride concentration using suppressed conductivity detection

“…An interesting approach to eliminate some of these problems was the analysis of sodium azide in tap water [25] and plasma samples [27] by ion-interaction reversed-phase liquid chromatography using a C 18 stationary phase and n-octylammonium ortho-phosphate as the interaction reagent. In these methods, the only sample preparation step was dilution, and the samples were stable for a longer time.…”
