[Studies on the analytical method for epichlorohydrin from internal can coatings].
An improved migration test was developed for determination of trace amounts of epichlorohydrin from internal can coatings. Eight kinds of sample cans, coated mainly with epoxy resin, for foods and beverages were prepared, and both their bodies and lids were tested for migration as follows. A body was filled with n-pentane and soaked for 2 hours at 25 degrees C. A lid was soaked in n-pentane (2 mL/cm2) for 2 hours at 25 degrees C. The test solution was analyzed by GC-FID and GC/MS using two DB-WAX capillary columns with different inside diameters. The limits of quantitation were 0.05 microgram/mL by GC-FID and 0.02 microgram/mL by GC/MS with selected ion monitoring. Recoveries of spiked epichlorohydrin were 99.9-104.5% at the level of 0.05 microgram/mL and 0.5 microgram/mL, with high precision. In this study, no epichlorohydrin was found to have migrated from any of the bodies and lids.
