摘要：

The photoplate detection system of a spark source mass spectrometer has been recently replaced by a detector array consisting of 20 separate small channeltrons for simultaneous ion counting of up to 20 trace elements. The new multi-ion counting - spark source mass spectrometry (MIC-SSMS) technique combines the advantages of conventional SSMS with modern on-line detection of elements. It has important analytical features, such as simple and fast solid-state sample preparation, high precision (about 1-2%) and accuracy (4%) using multielement isotope dilution, high sensitivity which leads to short measuring times (10-50 min) and low detection limits (about 0.001-0.01 mu g/g).
