Connecting the Gases and Cooling Water
After the instrument has been moved into its position, it can be connected to the
various services in the laboratory.
Connecting the Gases
All gas hose connections use 1/4 inch Swagelok fittings.
Note
Use two wrenches when making Swagelok connections. Use a space collar (Part
No. 09920584, supplied in the hose kit) at each Swagelok connection. Tighten the
Swagelok nut until you can no longer turn the knurled space collar. Only if you
cannot locate a space collar, tighten the nut until it is finger-tight, then turn it an
additional 1/4 turn with a wrench. Pre-swaged fittings should be turned 1/8 turn
past finger-tight. Do not over-tighten fittings. Check for leaks with all the
connections made.
Caution
The pneumatic tubing kinks easily. Install it so that it is less likely to twist, fold and
kink

Connect the gases to the instrument as described in the following procedures.
Connecting the Nitrogen Supply
1. Connect the instrument to the nitrogen supply using the nitrogen hose (Part No.
N0690275, uses 1/4-in. Swagelok fitting) using a 1/4-in. space collar (Part No.
09920584) on both ends of the tubing. Refer to the following figure.
2. Set the nitrogen supply regulator between 275 kPa and 825 kPa (2.75 to 8.25
bar or 40-120 psig).
3. Check for leaks using a proprietary leak testing fluid for high purity gas lines.
