4.3.2 Set-up for Double-Shot Analysis and operation procedures
From the menu bar, select
“Tools” – “Analytical Modes” – “Double-Shot Analysis” or click on
“Double-Shot Analysis” icon (A) on the toolbar. The set-up screen shown in Fig. 4.9 is displayed. In
this analysis mode, thermal desorption (TD) and pyrolysis (PY) can be performed sequentially.
(1) Check the Furnace and Interface checkboxes (B) to turn on heaters.
(2) Fill in parameters for thermal desorption in E through I. If a single step thermal desorption is to
be done, enter
“0” in the second row in the “Rate” column.
(3) If pyrolysis is to be done following the thermal desorption, check the checkbox in D, and enter
parameters for thermal desorption in J through K.
(4) If auto sampling is to be done using the Selective Sampler, and/or if auto cryo-trapping is to be
done using the MicroJet Cryo-Trap, check the checkbox for each step desired in L.
