4. Ensure that there is sufficient gas for the analysis.
Typical nitrogen gas consumption per day (when nitrogen is on 24 hours per day) is
between 5560 L (196.3 ft
3
) and 26700 L (943 ft
3
). If necessary, replace the tank. The
ETD module consumes less than 1 ATM cc/m of reagent carrier gas, so a standard large
bottle (245 ft
3
) of gas should last approximately two years.
For more information about gas requirements, refer to the LTQ Series Preinstallation
Requirements Guide .

it on.
