4.4.2.2 Other set-ups for Pyrolyzer furnace
C: The temperature display can be switched between the first decimal place and integer.
D: The equilibration time between the time for the furnace and interface temperatures to reach the
set points and the time before starting the next operation can be changed.
E: Maximum input temperature for all analytical modes
F1: Sets the upper limit for the number of analytical runs. A message urging you to perform
maintenance of the instrument will be displayed when the total accumulated runs reach the
number set here. After performing the necessary maintenance (septum, liner, needle, etc.) is
finished, click on the “Clear” button (F2).
4.4.2.3 Checking valves operations
Valves which are controlled by the pyrolyzer (EM valves for Pyrolyzer cooling air, Selective Sampler,
MicroJet Cryo-Trap, and Carrier Gas Selector) can be functionally tested (i.e., opened and closed).
This is done by checking the checkboxes in Manual valve check (I). Closing the Maintenance screen
will bring all valve operations back to normal.
4.4.2.4 Set-up MicroJet Cryo-Trap
G: Allows calibration of temperature sensor.
H: Sets the cryo trap temperature. Keeping the temperature equal or lower than -170°C for 90
seconds will activate the operations of the MicroJet Cryo-Trap.
