The first OOS occurred when a chemist used the caps with non-cut septa on the Shimadzu HPLC. All vials had the first injections with significantly lower areas than the following injections. Prior to this OOS, we allocated the caps with non-cut septa for the Dionex HPLC, and the caps with pre-cut septa for the Shimadzu HPLC.
HPLC • Very inert, therefore also as a coating on most other sealing discs • No elastomer-> No sealing-> No reclosing properties • Do not press-fit into caps; Are therefore often only sold unassembled • Very cheap • Only for very uncritical applications • Are often used on VWR (Merck) / Hitachi and Waters instruments

Quality vials are essential for reliable analytical results. All Waters Certified Vials are tested by LC or LC/MS to assure quality and cleanliness. The test results confirm the vials, cap and septa have been properly manufactured, handled and packaged, and are free from any potential contaminants which could result in chromatographic ghost peaks.
Sample Vials Wide selection of vials, including HPLC Certified vials (tested by HPLC for cleanliness) and LCMS Certified vials (tested for total ion count and presence of clusters in the high mass range). These are the cleanest vials in the industry.
When using commonly available 9 mm vials, the end point for optimal sealing is subject to the judgment of the operator. Sample vials and caps employing a definite end point or “stop” for the optimal amount of torque applied to the samples provides a perceptive end point position for the closure onto the vial.
