Table 1.

Linearity and sensitivity data for organic acids (lactic, glycolic, malic acids) used as a standard.

Compound RT Ion (m/z) Linearity Range (µg/mL) R2 * LOD a
(µg/mL)		 LOQ a
(µg/mL)
Lactic acid 14.038 147, 73, 261 15–242 0.9977 0.156 0.317
Glycolic acid 14.265 73, 147, 247 12–379 0.9955 0.101 0.410
Malic acid 15.256 73, 147, 259 12–758 0.9986 0.085 0.339

Experimental conditions as in Section 3.4. * For R2 the correlation coefficient. The p value was <0.0001 for all calibration curves. a LOD were based on S/N = 3; LOQ were based on S/N = 10.
