The Use of Micro-HPLC and Capillary Zone Electrophoresis for the Analysis of Individual Raindrops

摘要

A new sampling procedure for individual raindrops with volumes of 4 nl - 4 #x3BC;l is presented. It is demonstrated that analyte concentrations in small volumes can be analysed using micro-HPLC and capillary zone electrophoresis (CZE). Results for the analysis of cations such as Na+, NH4+, K+, Mg2+, Ca2+, and anions such as Cl#x2212;, SO42-, NO3#x2212;, NO2#x2212;and organic acids are given and discussed.
