syntax is: macro "<macro name>.mac",go. The macro will run
after each analysis and send a report to the designated printer.
From the command line
From the Data Analysis view, type the macro command (same
syntax as above) into the command line and press Enter.
To modify the noise start time
Noise measurements normally start at 3.8 minutes. If you notice
a contaminant peak in that area, you can change the start time
with this syntax: macro "<macro name>";cko_p (or s) 3. Use p for
phosphorus and s for sulfur. The noise measurement will now
begin at 3 minutes.
1 Gather the following:
 Evaluation column, HP-5 30 m x 0.32 mm x 0.25 µm
(19091J-413)
 FPD performance evaluation (checkout) sample
(5188-5953)
 Phosphorus filter
 Sulfur filter and filter spacer
 4-mL solvent and waste bottles or equivalent for
autoinjector
 2-mL sample vials or equivalent for sample
 Chromatographic-grade isooctane for syringe wash
solvent
 Inlet and injector hardware
Verify the following:
 Capillary column adapter installed. If not, install it.
 Chromatographic-grade gases plumbed and configured:
helium as carrier gas, nitrogen, hydrogen, and air.
 Empty waste vials loaded in sample turret.
 4-mL vial with diffusion cap filled with isooctane and
inserted in Solvent A injector position.
Verify that the Lit Offset is set appropriately. Typically, it should
be about 2.0 pA for the checkout method.
Replace consumable parts (liner, septum, traps, syringe, and so
forth) as needed for the checkout.
Install the evaluation column. (See the procedure for the SS or
