✦ Synopsis

repeated runs on one single capillary column. This is illustrated in the analysisofa realsample (Figure I), onacapillarycolumnwhich had taken more than 50 samples.The quantitative resultobtained, 7 ppm of Arochlor 1260, was confirmed by official Government Laboratories.

Figure 1

Waste oil containing 7 ppm of Arochlor 1260. treated samples: silica, silica and benzenesulfonic acid, and aminopropyl cartridges. Both linearity and recovery proved to be excellent when using solvent extraction in combination with solid phase extraction on aminopropyl cartridges.

Further evidence for the efficiency of the clean-up procedure follows from the fact that no loss of resolution is observed after References

The experimental results are represented in Figure 1 ; as in ref. [5], the log k'and Csaxes have opposite directions. Although only few values of solubility are available, the variations of log kvalues and log CS values of 2-hydroxynaphthalenc? are clearly seen to be parallel; some deviations are

The chromatographic performance of the deuterated solvents, CD30D and D20, has been investigated in reversed-phase micro high performance liquid chromatography. The chrornatographic performanceof CD30D is only slightlysuperior to that of CH30H. However, the performance of D20 is significantly superi
