🔧Work Performed
Customer was describing issues of headspace sampler intermittently skipping vials during overnight sequence run. Customer sent video recording, wherein the CDS showed the reason the vial was skipped; it was due to said vial failing the vial leak test. Suggest customer adjust sequence parameters so that headspace continues with vial injection. Upon arrival, performed leak and restriction test for the headspace, which failed. Investigated the headspace pneumatics and found the transfer line nut loose. In addition, the metal ferrule was not crimped on the nut. Transfer line was broken upon accessing the pneumatics area. Replaced transfer line and re-ran leak test, which passed. Customer ran samples, and headspace appeared to be behaving as expected.
