Selective detection and identification of pesticide residues,ed rapidly. The use of these chemicals has permitted the production of higher quality agricultural products with greater yields per acre. However, these advantages have not been achieved without corresponding disadvantages. Organic chemicals are more difficult to remove from food products than the i

Applications of the microcoulometric titrating system as a detector in gas chromatography of pesticgraphy is a very valuable tool for pesticide residues. This technique does a very good job of separating complex mixtures. Also pointed out is the need for a specific detector, because the residue chemist is plagued with associated crop extracts that probably never are completely removed from a samp

Applications of polarography for the detection and determination of pesticides and their residues,t the dropping mercury electrode. He further limits the term “polarography” to the capillary mercury electrodes, i. e., the dropping mercury electrode or streaming mercury electrode, because of their unique property of giving exactly reproducible results.

Polarography for the determination of organic feed medicaments,graphic or chemical procedures. While many of these methods are well established and quite satisfactory, some have limitations in terms of time required for analysis, their non-specific nature, or erratic results. The use of polarography for the analysis of feed additions has been investigated by se

The potential of fluorescence for pesticide residue analysis,omatography. However, it does have certain advantages over the classical methods of analysis in cases where it can be used. The possible uses of this technique for residue purposes have not been thoroughly explored. It is important that the residue chemist consider all possible techniques available

Determination of pesticide residues by neutron-activation analysis,th its attendant high neutron fluxes. It became considerably better known during the 1950’s, when the activation analysis service of the Oak Ridge National Laboratory made the technique available, at least indirectly, to any interested persons. More recently, the development of lower-cost, high-perf
