Septum grade | Material | Thickness | Hardness | Max. Temp. | |
| Standard septa (ST) | beige silicone | 4 mm | 60° shore A |  | |
| High temperature septa (HT) | red non-bleeding silicone | 3 mm | 60°shore A | 320°C * |  |
| Silicone septa, soft | transparent silicone | 3mm | 45°shore A | 250 °C |  |
| Silicone / PTFE septa | white silicone, one side coated with grey PTFE | 3 mm | 200 °C |  | |
| When used at considerably higher temperatures – and working without septum purge – interfering peaks can occur due to thermal decomposition of the material. | |||||
Retention Gaps
The retention gap technique in combination with on-column injection allows concentration of a large sample volume in the capillary column.
Choice of the retention gap depends on the solvent used:
| Me-Sil retention gap | Only for use with n-hexane and diethyl ether |
| Phe-Sil retention gap | for all solvents except methanol and water |
| CW retention gap | for all solvents and especially for methanol and water |
Me-Sil retention gaps are more inert than Phe-Sil, while Phe-Sil is less susceptible to contamination.
| Retention Gaps | Available 10mtr & 25mtr |
|---|---|
| Methyl-Sil deactivated (max. temperature 320 °C) | 0.25 mm ID (0.4 mm OD) |
| Phenyl-Sil deactivated (max. temperature 320 °C) | 0.32 mm ID (0.5 mm OD) |
| CW deactivated (max. temperature 25 °C) | 0.53 mm ID (0.8 mm OD) |
PRE Columns (Deactivated Capillary Columns)
Recommended application: for preparation of capillary columns as precolumn, whenever a larger contamination capacity is required.
| Pre Columns | Available 10mtr & 25mtr |
|---|---|
| Methyl-Sil deactivated (max. temperature 320 °C) | 0.25 mm ID (0.4 mm OD) |
| Phenyl-Sil deactivated (max. temperature 320 °C) | 0.32 mm ID (0.5 mm OD) |
| CW deactivated (max. temperature 25 °C) | 0.53 mm ID (0.8 mm OD) |
