Table 1 Regression and validation parameters of the proposed HPLC method for determining pure DIP and HBB samples.

From: “Eco-friendly HPLC method for analysis of dipyrone and hyoscine in different matrices with biomonitoring”

  1. *Average of three determinations
  2. aThe intraday (n = 5) relative standard deviation of concentrations (2,10,20,30,35 ug/mL) of DIP and (5,15,25,45,50 ug/mL) of HBB repeated three times within the day.
  3. bThe interday (n = 5) relative standard deviation of concentrations (2,10,20,30,35 ug/mL) of DIP and (5,15,25,45,50 ug/mL) of HBB repeated three times in three days.
  4. ca Calculated from equation [LOD = 3.3 (SD / S), LOQ = 10 (SD / S); where SD is the standard deviation of intercept, and S is the slope of the calibration-curve.
