Parameters of regression equations for calibration curves and range.

Compound						Range (g/mL)
GlcNAc	−7.353e^−4	4.489e^−1	12.327	79.609	0.9999	25–200
GalNAc	−1.922e^−3	6.089e^−1	−4.936	252.349	0.9997	10–160

For each curve the equation is , where is the peak area and is the concentration of the analyte (g/mL).
is the third degree constant.
is the second degree constant.
is the first degree constant.
is the intercept.
