Conducting a Multiple Level Calibration
Table 14-1 Conduct a multiple level calibration
Step Description
1 If a multiple level calibration is required, run sample calibration standards of different
concentration levels.
2 The known concentration of components in the calibration gas must be recorded in the
Peaks/Groups table.
Click Method >> Peaks/Groups. The Peak/Group Tables window will display. Use the scroll
bar to display the columns for Level 1, Level 2, etc.
3 Type the concentrations for the component at each level. Repeat this for all peaks and groups
in each of the channels.
NOTE: Each level represents one calibration gas standard.
Select a channel to add or edit calibration information via the dropdown list on the tool bar.
4 Connect the calibration gas. Ensure that the tank is properly regulated to between 1-25 PSI,
if going direct to the 3000 Micro GC inlet. Turn on the desired calibration gas.
Connect the calibration gas to the front inlet of 3000 Micro GC. Ensure that the calibration
gas output pressure and the 3000 Micro GC inlet is properly regulated to between 1-25 PSI.
Open the gas cylinder to begin gas flow to the instrument.
5 Click Control >> Single Run to run the sample on the desired method. Type the Sample ID
into the box and click Start. After the run is complete, ensure all peaks are integrated
and annotated.
