Calibration standard curve metrics for 4:2, 6:2, and 8:2 FTOH. Method sensitivity for GC-MS FTOH detection is reported as lower limits of detection (LLOD) and lower limits of quantification (LLOQ), the lowest concentrations at which the chemicals may be considered present in the samples and reliably quantified, respectively.
| Curve Equationa | Rb | LLOD (ng/μL) | LLOQ (ng/μL) | |
|---|---|---|---|---|
| 4:2 FTOH | y = 53.1x | 0.99 | 0.36 | 1.1 |
| 6:2 FTOH | y = 25.8x | 0.99 | 0.083 | 0.25 |
| 8:2 FTOH | y = 21.0x | 0.99 | 0.089 | 0.27 |
