6. Press EDIT and CALCONC to enter the concentration for each enabled
compound.
Use the arrow keys to enter the concentration.
If the concentration displayed in the Cal column is correct, move to the next
compound.
Move through the list and check that you have enabled all the compounds
contained in the calibration gas and have entered the correct calibration
concentration.
NOTE: Compounds not contained in the calibration gas must be removed from the library,
see Removing Library Compounds on page 236.
7. To switch to the ECD view, press DISPLAY, GC, and DET, and when
prompted to change views press Enter Menu.
8. To select the ECD compounds for your application, press Enter Menu, then
LIBRARY and LIST, and press the left/right arrow to select the library that
matches your selected column.
The status line at the top of the screen will tell you which library you are using.
Compounds with a check mark are currently selected for calibration. If the
compound is not selected, remove it from the library.
9. Press EDIT and CALCONC to enter the concentration for the compound.
If the concentration displayed in the Cal column is correct, move to the next
compound.
Move through the list and check that you have enabled all the compounds of
interest and have entered the correct calibration concentration and again
remove any unwanted compounds from the library.
10. Connect a supply of calibration gas, as discussed on page 218, or prepare a
syringe sample.
NOTE: Your calibration gas must both PID and ECD calibration compounds. If your
calibration gas contains only the PID compounds, then you must calibrate each
detector separately.
11. Press Start Stop to begin an analysis.
