Spectrophotometric determination of bromine with dipropyl-p-phenylenediamine (DPD) in drinking water, swimming-pool water, wastewater, and disinfection solutions in a range of 0.020 – 10.00 mg/L.
The primary column is used to determine presence of the target analytes in the sample; the secondary column of a different selectivity confirms whether a positive match.
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination
