Mar 17, 2009 · New PRE-CUT Septa for HPLC Applications. Mar 17 2009. In HPLC often slitted or cross-slitted Silicone/PTFE Septa are used, in order to offer a penetration aid for the fairly thick and dull needles used in the HPLC instruments. While the instrument needle requires the slitted septa, the user may run into the risk of concentration changes due to

Used primarily for routine analysis in gas chromatography with FID, TCD and FPD detectors or HPLC with UV/Vis or RI detectors, PTFE/Synthetic Red Rubber septa offer good resealability and excellent chemical inertness before puncture. The low durometer of red rubber allows for easy needle penetration even with thin bore GC needles.

Jul 23, 2020 · By definition, According to the definition, Septa is a circular gasket made of Silicone or silica gel. In HPLC analysis, Septa is usually placed in the Cap of the HPLC Vial to seal the HPLC Vial to ensure that there is no gap between the Cap and the Vial.Aijiren's Septa uses a double-sided material, and the combination of PTFE and Silicone

Oct 19, 2015 · 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.
