Calibration data gave correlation coefficients ranging between 0.99559 and 0.99999, showing the detector response to be linear in the concentration ranges employed.
Some spuriously high recoveries were obtained in the preliminary test, but these were not considered to invalidate the study. Use of lower concentrations in tests 1 and 3 produced recoveries around 100% (90.6% - 106.7%).
No peaks at the characteristic retention volume of the test substance were obtained in the chromatograms of the blank solutions, indicating that the analytical procedure was free from interferences.
