Abstract An improved cleanup procedure for fresh spinach extracts, using silicic acid-glass fiber sheet, was compared directly with the activated Florisil column procedure. The new cleanup method requires about one-half the time necessary for the Florisil column method. The pesticide concentrates were analyzed by quantitative GLC, using a 2’ column of OV–17 and a 90Sr detector. Recovery experiments on 100 g samples fortified with 4 major chlorinated pesticides showed the 2 methods to be comparable.

Abstract A method for the determination of the preservative dehydroacetic acid (DHA) in strawberries, bananas, and zucchini squash is described. The samples are blended and extracted with chloroform. The chloroform extract is cleaned up on a preparatory silicic acid-glass fiber sheet. The DHA is determined by its ultraviolet absorbance at 307 nm. The average recovery of DHA added at levels of 5 to 80 ppm was 100.2 ±4.8% (15 analyses). The method is sensitive to 2 ppm DHA.
