Table 2.

Linear correlation, ranges, and lower limit of detection of β-agonists selected.

Standard Regression equation Coefficient (R2) Linear range (μg/L) Limita (μg/L)
SAL y = 739.36x + 9907.5 0.9970 0.2–25 0.02
RAC y = 632.53x − 10048 0.9992 0.4–50 0.05
CLB y = 713.86x −12933 0.9901 0.4–50 0.05

CLB = clenbuterol; RAC = ractopamine; SAL = salbutamol.
