Determining Sodium Azide Concentration in Blood by Ion Chromatography

Abstract: We describe a simple method for measuring sodium azide concentrations in aliquots of blood and other tissues. Aliquots are acidified, converting azide to volatile hydrazoic acid (HN3) which is then trapped in sodium hydroxide. We analyze the resulting aliquots by ion chromatography, using a sodium tetraborate eluent and suppressed conductivity detection. The method is sensitive to at least 100 ng/mL.

“…Due to its high specificity the GC-EI-MS-MS method of determining sodium azide in blood and urine distinguishes itself from other methods reported in the literature [8,13,14,19,22,23]. The study presents no linear equations for calibration curves, as calibration points represent a better fit with curves described by power functions (Fig.…”

“…Ze względu na dużą specyficzność opracowana metoda GC-EI-MS-MS oznaczania azydku sodu we krwi i moczu wyróżnia się na tle innych metod opisywanych w literaturze przedmiotu [8,13,14,19,22,23]. W pracy zrezygnowano z liniowych zależności dla krzywych kalibracyjnych ze względu na lepsze dopasowanie punktów kalibracyjnych do krzywych o przebiegu funkcji potęgowych (ryc.…”
