Applications of polarography for the detection and determination of pesticides and their residues, 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.NICHE 发表于 2025-3-24 08:27:42
Polarography for the determination of organic feed medicaments,ographic 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 s单片眼镜 发表于 2025-3-24 12:48:12
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洁净 发表于 2025-3-24 18:08:25
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-perfERUPT 发表于 2025-3-24 20:58:12

Individuals now are more often studied in their natural environments, and interactions between the environment and the individual are taken into consideration, even though many featurAcclaim 发表于 2025-3-25 00:57:21
