Plastics. Determination of caprolactam and its cyclic and linear oligomers by HPLC. | Status: Superseded, Withdrawn

1 Scope This International Standard describes an HPLC (high-performance liquid chromatography) method for determining the concentrations of cyclic oligomers of caprolactam, from 0,01 % by mass upwards, and linear oligomers of caprolactam, from 5 mg/kg upwards, both up to and including the hexamer of caprolactam (n = 6), in samples of polyamide 6, caprolactam and mixtures of rearrangement products in water.
