✦ Synopsis

An air sampling and liquid chromatographic separation method for melamine is described. Collection efficiency on 13-mm glass fibre filters was determined. No breakthrough was detected under a contamination level of 0.4 mg/m3 for 40-1 air samples. The detection limit for a 60-1 air sample at 215 nm is 450 ng/mg. Retention behaviour of melamine on four different reversed-phase columns is described. Column packings tested are Spherisorb ODS, Supelcosil ODS, Spherisorb CN and PRP-1. Results of electrochemical detection studies are discussed.
