Tubing material:

Chemical identification method:
UV-Vis absorption, retention time matching to standards.

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 curve of commercial, or fractionated standards. For fractionated standards, they are collected in preweighed vials, reconstituted in solvent and re-injected to determine senstivity.

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

Calibration schedule:

Uncertainty estimation method:
Uncertainty is estimated at +/- 5%, and propagated from standard deviations of the calibration curve, uncertainties in injection volume.

Known interferences:
