During the initiation of an analysis, the GeoPyc® 1360 prompts the user to enter a conversion factor. The GeoPyc Operator’s Manual and Quick Reference Guide give an adjusted conversion factor for each chamber. Using these conversion factors should yield reliable and reproducible results for most sample types. To obtain closer agreement with established methods, however, you must perform a calibration run to obtain the best conversion factor for the specific shape(s) of sample you are analyzing.
Performing a calibration run is simple, and it only takes about the same amount of time as performing a single sample analysis. If you record the resulting calibrated conversion factor, you do not need to repeat the calibration run frequently.
To understand the importance of performing this simple procedure, it is helpful to understand how the conversion factor is used, what is the role of calibration, and which types of samples benefit most from calibration.
