Table 1.

Linear ranges, calibration curves, correlation coefficients (r2), and detection limits of 5-FU and 5-FDHU.

Compounds Linear Ranges (µg/mL) Calibration Curves r2 LLOQ (µg/mL) LOD (µg/mL)
5-FU 0.1–50 y = 0.126x − 0.015 1.0000 0.1 0.05
5-FDHU 0.1–50 y = 0.066x − 0.001 1.0000 0.1 0.05

LLOQ: Lower limit of quantification at a signal-to-noise ratio (S/N) of 10; LOD: Limit of detection was determined at a signal-to-noise ratio (S/N) of 3.
