The use of HPLC and GC certified vial kits are an important way of reducing sources of error and ensuring that processes are reproducible.

• Each batch of HPLC and GC certified kits is tested on 15 critical parameters. In a realistic method, an HPLC/UV and GC-MS test of vials/closure combination of blanks and contaminations will be carried out
• The batch-specific test certificate, with the HPLC and GC chromatograms, can be handed out upon request
