Guide to select an injection port septum
Even when a low bleed septum is used, bleeding is not totally eliminated. The type of bleeding differs according to the septum type and bleeding appears as different peaks on a chromatogram. In high-sensitivity analysis, you need to select and use a septum that does not cause bleeding at a position where interference occurs with the target compound.
Use the information below as a guide.
| Injection unit temperature is high (250 to 450℃). | Low bleed (high-sensitivity analysis) | Septum for HT high temperature |
|---|---|---|
| Low bleed septum is not required. | Long-life septum | |
| Injection unit temperature is lower than 250℃. | Low bleed (high-sensitivity analysis) septum is required and durability is also important. | Long-life septum |
| Small amount of plasticizing agent regardless of the injection unit temperature | Thermogreen LB-2 septum | |
