Septum Vial Cap Selection: Factors to Consider for Optimal Sample Security
How to Diagnose GC Septum Bleed Contamination Sources: Could Multiple injections can core the vial cap septum and lead to significant GC septum bleed. Resistance to coring varies by septum material (Figure 5). Coring can be minimized by preparing separate vials for replicate injections, when feasible, and by carefully considering the type of septum material when multiple injections are necessary. Screw Cap Septum Vials – Thermo Fisher Scientific Catalog number: TS-13019. For a conveni...
