Figure 2
Cartridge-type sample reservoir. (a) Schematic cross-sectional view (top) and photograph of the cartridge with inserted Teflon parts (bottom) to form a tight seal. The two Teflon balls for the 70 µl cartridge reservoir have a diameter of 2 mm. The barrel-shaped part for the 200 µl cartridge reservoir consists of a Teflon part (8 mm in length, 4 mm in diameter) and two O-rings (OD of 4 m, ID of 2 mm). (b) Connector tool for sample loading from a Hamilton syringe into the sample reservoir. The connector tool consists of two metallic parts, a metallic ring spacer (OD of 12 mm, ID of 10 mm), an O-ring (OD of 6 mm, ID of 4.5 mm) and a Teflon syringe adapter (8 mm in length, 7 mm in diameter). The parts A and B are 11 mm long and 23 mm in diameter. Each part is assembled as shown in the bottom view, and then the Teflon balls are moved to the left end by a thin stick. Subsequently, a 100 µl gas-tight syringe (No. 81065, Hamilton) loaded with sample is connected to the tool. The sample is loaded into the cartridge from the syringe thorough the tool until the Teflon balls reach the right end. In the top view, grease colored with red ink was used as the sample. An underfilled sample reservoir is also available for sample injection by the HVC injector. |
