Xtra Life Septum (25 pcs) |
227-35511-01 | Brown | Unique two-piece design ensures a leak-free seal and minimizes particulates generated from repeat injections. Ideal for trace-level analysis and lasts up to 10 times longer than standard septa. - Maximum temperature (INJ setting temperature): 400 ℃ |
 |
Premium Green Septum (50pcs) |
227-35004-01 | Green | This low-bleed septum is heat resistant. It helps inhibit components bleeding even during high-sensitivity analysis. Made of crack-resistant material, it offers superior durability, sealing performance and solvent-resistance. - Maximum temperature (INJ setting temperature): 350 ℃ |
 |
Standard type (20 pcs) |
201-35584 | White | General-purpose septum |
 |
HT Septum (20 pcs) |
221-48398-91 | Brown | - Suitable for high-sensitivity analysis at high temperatures - Maximum temperature (INJ setting temperature): 450 ℃ |
 |
LL Septum (20 pcs) |
221-48972-91 | Blue | - Suitable for high-sensitivity analysis - Maximum temperature (INJ setting temperature): 450 ℃ |
 |
Enduro Blue Septum (50 pcs) |
221-75180 | Light blue | - Low-bleed - Maximum temperature (INJ setting temperature): 350 ℃ |
A low-bleed septum is not completely free of bleeding. The type of bleeding that occurs varies with the septum and results in different patterns on chromatograms. Inthe case of high-sensitivity analysis, it is necessary to select a septum whose bleeding will not occur at a point that interferes with the peak of the target compound.Conditioning for several hours between 120 ℃ and 200 ℃ after extraction with hexane may help to reduce bleeding.
In the case of using a syringe for AOC, it is recommended to exchange the septum after about 100 injections. If the outside diameter of a needle of a gastight syringe is thick, it is recommended to exchange after about 50 injections.
