Your GC/MS calculation method controls how compounds are identified, quantified, calibrated, and evaluated. In this video, I walk through the key calculation-method parameters in Agilent EnviroQuant and show what I review when setting up or checking a method. I cover: • Compound identification settings • Internal standard assignments • Quantitation and qualifier ions • Retention-time parameters • Calibration levels and concentrations • Calibration curve and response-factor se
