This video provides a key understanding about Agilent Gas Saver Mode. The specific question to be answered in this video is should Agilent Gas Saver Mode always be turned ON ?
Gas saver is recommended, the only time you really need full split flow is for injection. Gas saver is usually configured to switch on after 2 minutes. For example, take a 100:1 split, your total flow would be something like 110 ml/min on the inlet at 1ml/min column flow constantly. With gas saver, it will only be that high at the time of injection for a 2 minute period. After that, the flow will be approx 24ml/min for the run and even in standby. A substantial savings in gas supply.
