Using EA IsoLink IRMS System for CNSOH
Performing a Jump Calibration
a. In the list of available Jump Calibrations, mark the one for H
b. Press Recalibrate Icon
5. Confirm with Yes, because you have already opened the Reference Port.
6. Start Jump Calibration Procedure.
a. Jump to CO (along hysteresis curve).
b. Perform a peak center for CO in order to get the signal height.
c. Jump to H
d. Jump to CO (not along hysteresis curve).
e. Perform a peak center for CO in order to catch the peak.

(for example 001).
– Slow: compensate hysteresis by Max/Min settings of the magnet.
– Fast: magnet setting of Jump Calibration.
– HV: high voltage setting of Jump Calibration.
Note If no Jump Calibration is available in the list, create a new one as shown below:
How to Create a new Jump Calibration:
• Click New.
• From Gasconfiguration, select H
• To Gasconfiguration, choose CO.
• Accept the default values.
• Click OK.
Note Magnet jumps are always from a low mass to a high mass (e.g. 2 to 28 at
H -> CO, or 28 to 44 at N
