13. After relieving the gas pressure in the hose, remove it from the refill port by
pulling the knurled collar down and extracting the fitting.

Connecting Carrier Gas
Explorer may be connected to an air or nitrogen cylinder for continuous operation.
A two-stage, high purity regulator capable of delivering 100 psig is required. Use
the carrier gas connection kit (MX380309)
1. Connect compression fittings to both ends of a length of the 1/8” Teflon tubing.
2. Set the external carrier delivery pressure to 100 psig (690 kPa).
3. Purge the Teflon tube to remove any contamination.
4. Plug the Quick Connect into the refill port on Explorer.
A continuous pressure of carrier gas must be maintained, even when the
instrument is not in use. This ensures
Explorer is ready for use at short notice
and prevents column contamination.
NOTE: The internal cylinder will empty until it is at the same pressure as the pressure being
delivered from the tank. The contents gauge may show 0 psi when Explorer
is operated from an external cylinder.
