Parameter Result
Linear range 5-10,000 mg/L (0.050- 100 mg/ml sample)
LODa 1.6 mg/L (0.0157 mg/ml sample)
LOQa 5.5 mg/L (0.0546 mg/ml sample)
Recovery 99% (at 1000 mg/L)
104% (at 1500 mg/L)
115% (at 1750 mg/L)
108% (at 2000 mg/L)
107% (average)
Variation coefficient (n = 5) Standard solution 1.2 %
E-cigarette liquid sample 2.1 %
  1. aLimit of detection (LOD) and quantitation (LOQ) were determined by establishing a separate calibration curve near LOD (5.0-25 mg/L). The limits were calculated from the residual standard deviation of the regression line [25].
