High-recovery vials enable sample concentration and injection without transferring to microvolume inserts. Micro-sampling vials offer a lower cost alternative to high-recovery vials. Conical inserts with polymer feet virtually eliminate dead volume and act as a shock absorber for needles.
Ensure optimal performance of your GC instrument with bleed and temperature optimized Aijiren Tech™ BTO and TR-Green Septa. Made of low-bleed silicone, these septa have excellent mechanical properties, are ideal for demanding GC-MS applications, and may be used reliably up to 400 °C.
The maximum operating temperature is 200° C. High Temperature GC Septa High Temperature Septa is made of preconditioned PTFE/silicone rubber and is 3.175 mm (0.125 in) thick. The average life of these septa is up to 100 injections with a 26s gauge needle. The maximum operating temperature is 212° C. Long Life GC Septa
The GC septum should be routinely replaced to reduce the risk of leaks and septum particle contamination. In fact, if the instrument is in heavy use, change the septum daily. Repeated use of the same septum will result in increased coring, which may introduce a leak and/or result in septum fragments being deposited in the inlet liner.
A popular and economical septa for general GC purposes PTFE/rubber – AC7, 8RT1 Harder grade of rubber for use with piercing needle. Most popular and economical septa for general GC purposes in Aijiren systems Pre-slit PTFE/red rubber – 8RT1X Pre-slit, high quality red rubber with a thin (0.003") layer PTFE.
Sep 1, 2005 · Reduce the risk of septum scoring by using tapered needles, which easily penetrate the septum. In combination with prepierced septa (supplied under the name BTO [Varian BV]), septum scoring is minimized. These septa have a hole in the middle, allowing easier access for the needle while maintaining the sealing characteristics.
Jul 10, 2012 · Septum C bleeds even at 100°C, suggesting its unsuitability in routine high-temperature GC–MS studies. Significantly, all septa used in this study bleed phthalate compounds at much lower IP temperature, contrary to the respective manufacturers’ claims on quality and usage.
