GC/MS and HPLC

Review (4/5)

What can be done to ensure measurement accuracy?

Never split samples and compare measurements, or you will see that the two values are different and an accurate measurement cannot be obtained.

Calibrate the instrument with known concentrations at least twice as high as the concentration expected in a sample to ensure that the calibration curve is linear.

Determine analyte recovery from a standard reference material.

All of the above.
