Day 1
4. Leak Check, Auto-tuning
Leak check
Check for air leaks with the instrument unheated, as described in section
4.2 Leak Check
of
the Operation Guide.
□
Is m/z28 within twice m/z18?
Set the temperature of the ion source, INJ, COL, and interface and repeat the check to
ensure stability.
□
Is the temperature stable (Has the READY lamp gone out?)
□
Is m/z28 within twice m/z18?
Auto-tuning
Check that auto-tuning can be conducted normally.
Conduct auto-tuning, as described in section
5.1 Auto-tuning
of the Operation Guide.
□
Is the detector voltage in the tuning report 1.8kV or less?
□
0.10 maximum discrepancy between FWHM for m/z69, 219, and 502?
□
Is m/z69, 131, 219, 264, 414, 502, and 614 mass-number displacement
C
0.10 max.?
Checks on the Peak Monitor window
□
Does the peak intensity change when each lens voltage is changed?
□
Does the m/z69, 219, and 502 peak amplitude drop below 0.50 when the RF offset is
increased?
The checkbox marks (
□
) indicate check items in the Installation Completion Checksheet
(ZEAV-0416).
Settings at the end of the initial day
Set a high GC total flowrate (100 to 200 mL/minute) to lower the residual air in the carrier
