Abstract:
The conflict between lab and process data has always existed because the process data doesn’t always match the lab data. The lab’s primary function is to validate and certify products and it is therefore the adjudicator should discrepancies in data arise. Consequently, if the two sources of information do not conform, the process side is required to make the necessary changes, corrections, and adjustments; hence the conflict.
This paper explores data results for petroleum fraction samples ranging up to C44 or 535 ºC end boiling point on a lab and a process gas chromatograph (GC) wherein the same hardware and methods were used. The two GC’s differ only in their sample introduction method. The paper will discuss the operational parameters and the differences in results from liquid syringe autosampler based inlets used in laboratories to rotary valve based inlets required in the process all leading to a fluid free calibration of the process GC.
