Conserve your GC carrier gas to help control costs

This calculator will determine the cost savings that could be realized by implementing Gas Saver with and without nitrogen standby. Simply complete the required fields at the top and the results will display below.

Agilent Gas Saver works with split/splitless and multimode inlets by reducing the GC split flow rate at a specified time after the injection while maintaining constant septum purge and column flow rates throughout the analytical run.

Combining Gas Saver with nitrogen standby can save even more if your system is not in continuous operation. This approach requires the helium conservation module for Agilent 8890, 8860, and 7890 GCs. Using the OpenLab CDS “SLEEP.M” and “WAKE.M” methods, the module automatically switches the carrier gas supply from helium to nitrogen during idle time, further conserving helium.
