Analysis of Pyridaben in 15% Emulsifiable Concentrate by GC

A GC method for the determination of pyridaben mass fraction was developed. Pyridaben was confirmed by the retention time and determined by an external standard method.The rsults showed that the correlation coefficient of Pyridaben was 0.99913, the variation coefficient was 0.21%, and the average recovery rates was 98.38%. The method is simple,rapid,accurate and suitable for the analysis of pyridaben mass fraction.
