Stops the Injection process and returns to Injection – Settings (Step 2).
Process data is not saved to the USB flash drive.

Stops the Injection process and returns to Injection - Settings (Step 2).
Injection Process results are saved to the USB flash drive.
If the baseline (B) does not drop to either 0 or a very small number (typically 1-3 ppm), then there is either
a leak in the system, or the system has not adequately “zeroed”. Try aborting the process, wait 2-3
minutes, and try again. If the problem persists, check the injection setup for leaks and ensure that the
absorber column is properly seated and contains fresh soda lime.
Injection – Injection Phase (Step 6)
During the Injection Phase, the syringe should be slowly and steadily injected into the airstream through
the septum. The injection rate should not exceed 3 ml/second to avoid over-pressurization of the system
(in other words, it should take the user at least 3 seconds to inject a 10 ml syringe).
