Direct Technique

Abstract TCA residues in wheat grain may be determined directly without extraction or cleanup. The chloroform formed by decomposition of TCA is collected in xylene and determined by microcoulometric gas chromatography. Two varieties of wheat grown in two different soil types and treated with TCA applied at the 1–4 lb per acre level were analyzed by this direct technique. By using the direct procedure as an arbitrary standard for 100% recovery, comparisons were made among three extraction techniques. Extraction of spiked wheat samples gave recoveries comparable to the direct method. Field-treated samples, however, gave poor recoveries. The results indicated that TCA is not readily extracted from fieldtreated samples, possibly because of combination with basic cell constituents.
