Packaging - Flexible packaging material - Determination of residual solvents by static headspace gas chromatography - Part 2: Industrial methods
This part 2 should be read in conjunction with prEN (261190) part 1 and describes rapid methods as commonly used in quality control for example for monitoring the level of residual solvents used in the production of flexible packaging by static headspace chromatography. The procedure described in this part involves one single injection of the headspace which implies an incomplete extraction of the solvent. The values obtained may be lower than the absolute content which should be determined according to Part 1. During the analysis there may be interferences from possible products of thermal decomposition.
