Data analysis method:

Quantification method:
Peak areas are converted to concentration by plotting on a calibration curve of standards, either commercial or generated, the amount of solvent used to extract filters, the injection volume, and the mass of the filter, correcting for particle wall loss.

Calibration method:
Calibration curves of commercially available standards, synthesized standards or fractionated standards. Fractionated standards are collected in preweighed vials, evaporated and weighed, then reinjected to determine the sensitivity of the compound. For compounds with no direct calibration, estimates based on sensitivities of analogous compounds containing the same functional groups are used.

Calibration drift estimate:
Low (on the order of weeks)

Calibration schedule:

Uncertainty estimation method:
Uncertainty is estimated at +/- 5%. Uncertainties are propagated from standard deviations of the calibration curve.

Known interferences:
