Azide may be formed during the production of certain pharmaceutical products. It can cause explosions during manufacturing. Therefore, its concentration in the air needs to be monitored in order to prevent such accidents. Azide (N3-) is well separated from standard anions on the Metrosep A Supp 5 - 250/4.0 under standard conditions.

Determination of arsenic in dust from a waste incineration plant is performed. This is required as the environmental risk depends on the degree of oxidation of the arsenic species. Due to the different pKa of the respective anions, selenite requires non-suppressed conductivity detection, while arsenate is best determined with suppression. The determination of both species is achieved by switching the suppressor in and out, respectively.

Determination of chloride, nitrite, nitrate, and sulfate in an ambient aerosol (PM2.5) using aerosol sampling with the PILS (Particle Into Liquid Sampler) and anion chromatography with conductivity detection after sequential suppression.

Determination of chloride and sulfate in dust using anion chromatography with conductivity detection after chemical suppression. Sample: dust sample Sample preparation: 0.1 g of dust dissolved in 100 mL c(HNO3) = 0.02 mol/L 0.45 µm filtration
