Chemical identification method:
Electron impact ionization fragmentation patterns.
Data analysis method:
Calibration drift estimate:
Medium (on the order of days)
Uncertainty estimation method:
Uncertainty is estimated as +/- 30% for particle mass. Uncertainty arises from transport efficiency as a function of particle size and shape.
Link to supplemental information:
All measurements from this instrument have uncertainties of 20% of absolute value.
All measurements from this instrument are normalized as a way to determine particle chemical composition.
