Conducting a Single Level Calibration
Table 13-1 Conduct a single level calibration
Step Description
1 Prior to conducting qualitative or quantitative analysis on 3000 Micro GC, it is necessary
to properly calibrate the instrument using a known calibration gas. The calibration process
identifies the elution order of the component peaks in a chromatogram, as well as the detector
response each component demonstrates with the instrument.
 If the sample gas concentration is close to the calibration gas, a single level calibration is
sufficient. Go to step 2.
 If the sample gas concentration varies over a broad range, a multiple level calibration is
recommended. See
3000 Micro GC Guide 14, Conducting a Multiple Level Calibration .
2 To conduct a single level calibration, run a sample of a calibration gas (i.e., a sample with known
component concentrations). The generated data file can be used to define the calibration peaks.
3 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 flow to the instrument.
4 Click Control >> Single Run to run the sample with the currently loaded method. Type the
desired Sample ID and click Start. After the run is complete, ensure all peaks are integrated
and annotated.
5 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 scroll until the Level 1 column is visible.
6 Enter the concentration for the component under Level 1. Repeat this for all peaks and groups
in each of the channels.
To add or edit calibration information, select a channel from the drop-down list on the tool bar.
