摘要：
A capillary gas chromatographic method was developed for the analysis of the degradation product pivalic acid in dipivefrin-containing ophthalmic solutions. The linear calibration range was 1.02 to 102 mu g/ml (r = 0.999) and recoveries were greater than 98%. The relative standard deviation was less than 4.2%. The method can be used to accurately monitor pivalic acid levels for routine quality control and is simple and reliable.
