I need some help with method parameters for an Agilent 5975C MSD. I went to the OFN.sn.m in my software but it looks like someone change all the parameters. I am wanting the original factory parameters Thanks Drew.

From Agilent 5975 series operation manual page 76,

To verify system performance
Materials needed
• 1 pg/μL (0.001 ppm) OFN sample (5188-5348)
Verify the tune performance
1 Verify that the system has been pumping down f or at least 60minutes.
2 Set the GC oven temperature to 150 °C and the column flow to 1.0 mL/min.
3 In the Instrument Control view, select Checkout Tune from the Checkout
menu. The software will perform an autotune and print the report.
4 When the autotune has completed, save the method and then select
EvaluateTune from the Checkout menu.
The software will evaluate the last autotune and print a System Verification
– Tune report.

Verify the sensitivity performance
1 Set up t o inject 1 μL of OFN, either with the ALS or manually.
2 In the Instrument Control view, select Sensitivity Check from the Checkout
menu.
3 Click the appropriate icons in the Instrument. Edit window to edit the

Your software may have a backup of the original method - mine is in "C:\MSDChem\mssetup\5975". All the original installation stuff is in there.
