For all of your analytical and biological applications, our vials, caps, and septa are made from the highest quality materials. Our portfolio consists of GC vials, caps, and septa. We also offer a choice of caps: Foil-lined urea -- best for airtight seal; Poly-cone line -- best for aggressive reagents; Poly screw cap -- basic plastic cap, no insert

PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical. PTFE/Silicone septa are offered in a standard formulation as well as a soft durometer formulation recommended for applications where ease of needle penetration is important PTFE/Silicone/PTFE Septa: (T/S/T)

Long Life GC Autosampler Septa are designed for use with GC Autosamplers. The 5, 9, 11 and 11.5 mm diameter Long Life septa are available with a unique pre-pierced center depression to guide the syringe needle to the same injection point, extending septa life, reducing needle bending and eliminates the common type of coring that occurs on the first injection.

Different septa material for LC and GC applications There are many different types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa When selecting which septa is right for your experiments, it

Jul 10, 2012 · Septa B and C are shown without syringe injections. Septum A was also found to become damaged after 25 syringe injections at 250°C, unlike Septum D. Results and Discussion Typical GC–MS chromatograms obtained using Septum A (sans sample injection) at increasing IP temperatures 100, 150, 200 and 250°C are shown in Figure 3.

The bleed from either septum shows a similar pattern (Figure 1), but it is easy to determine the source with a simple test. Isolate the inlet by setting the instrument to perform a run without an injection. Perform an analysis; if the bleed disappears, then the vial cap septum was the source. Determining if the vial cap septum is the source of

A GC septum is located at the top of the injection port and serves two functions: 1) providing a leak-free seal to maintain carrier gas pressure inside the system 2) handling repeated puncturing by a syringe needle for sample introduction purposes without severe coring or leaking.

Which Septa Should I Use? Thermolite Plus septa are a proven low-bleed champion. With a maximum temperature of 350 °C, Thermolite Plus septa are suitable for most applications. BTO septa are bleed and temperature optimized with a maximum temperature of 400 °C, for the most demanding GC and GC-MS applications. They attain remarkable softness and

septa and a competitor’s “replacement” septa, which are packaged in a plastic bag. In each of these analyses, a single septum was sealed in a 10-mL static headspace vial. The sample was then analyzed in an Aijiren Headspace Sampler. After heating the septa to 150 °C and equilibrating for 1 hour, a 1-mL sample was analyzed by GC-FID.
