9. Position the holder for the microfluidics splitter upright and use two 7 mm wrenches to
secure it. See Figure 378 .
Figure 378. Securing the Holder for the Microfluidics Splitter
Preparing the NoVent Microfluidics Restrictor Tubing
If you are using helium as a carrier gas, use the 30 cm length of 75 μm fused silica tubing in
your kit (two are supplied) to connect the NoVent Microfludics module to the splitter.
If you are using hydrogen as a carrier gas, use the 80 cm length of 75 μm fused silica tubing in
your kit (one is supplied) to connect the NoVent Microfludics module to the splitter.
This tubing acts as a flow restrictor to limit the helium flow from the NoVent microfluidics
module.You must swage a SilTite™ ferrule to this tubing.
You will need the following materials to connect the tubing to new ferrule and nut. They are
all included in the complete kit.
• SilTite FingerTite™ pre-swage tool—to pre-swage the SilTite FingerTite ferrule to the GC
module
• SilFlow™ pre-swage tool and SilFlow FingerTite tool—to pre-swage the SilFlow ferrule to
the microfluidics splitter
• SilFlow nut—to connect the tubing to the microfluidics splitter
• SilTite ferrule (1)
• SilFlow ferrules (3)
1. Use a scoring wafer to cut the end off the tubing.
2. Use the SilTite FingerTite pre-swage tool in your kit to pre-swage the SilTite ferrule to
your tubing. See Figure 379 . The tubing should extend just past the tool when
pre-swaging the ferrule. After the ferrule is swaged, remove the tool and confirm the
ferrule does not slide on the tubing.
Note
If you are using a 0.25 mm id column, use a 0.4 mm SilFlow ferrule and a 0.4 mm
SilFlow FingerTite jig. If you are using a 0.32 mm id column, use a 0.5 mm SilFlow
ferrule and a 0.5 mm SilFlow FingerTite jig.
