Checking calibration standards against calibration table

[unclebenjaminjones]

I am using an Agilent 1200 Series HPLC with Chemstation Software. I am testing for RDX in wastewater at an explosives plant. I must run a check standard everyday to see if it is within 3 % of the value of the same standard in the calibration table. I know I can put this information into an excel spreadsheet to record the check. Is there a function in Chemstation that would call the standard check acceptable or not acceptable based on this range and the value in the cal table? I may even check more than one standard against the cal table.

Also, when I tested pharmaceuticals, we would do a system suitability check daily. Is this necessary if I am running this check against a calibration table that indicates everything is working in the same manner as before?

Is there a 'system suitability' type feature in Chemstation?

Thanks for any input you may have.

I'm not sure for LC Chemstation, but in GC Chemstation (Enviro Quant Mode) There a "Continuous Caliibration" function. You have to edit which calibration level you want the report to compare to first. Then you print the CC Report. There are a few options for the report but typically it will show you % deviation from the original calibration. Of the three ways to install GC Chemstation (Enhanced, Enviro, and Drug) I know it is not available in Enhanced Mode (not sure about Drug). Usually you have to specify the mode during the install of the software and I'm not sure if these options are available for LC Chemstation. It's worth a try i suppose. I know that the command "CCRPT" will print the "Continuing Calibration Report" and "CCCHK" Performs the initial calc against the curve. Most of the time commands work between LC and GC chemstation and the command structures are similar. I'm not sure how to specify the CC level using commands though.

There should also be a way to use custom reports/database to check this and keep a log of all your check standards. There is a video on how to set up the database to do this on Agilents website (again, if this function is available for LC chemstation).

Sorry I can't be more help to you.

Sorry for the mistype. The "GC Chemstation" I referred to earlier is actually "MSD Chemstation." Particularly Rev. D.01 through E.02.
