In a paper by Koch et al.4 in 1957, it was assumed that in the case of the lymphomatous diseases, the plasma zinc leve

Trace elements in \(5-\mu\) l sample solutions deposited on a substrate were determined by secondary ion mass spectrometry employing the internal standard method. A simple sample mount made of copper was devised to restrict the sample residue within a small area. The absolute detection limits of 22
The trapping efficiency of 14 solid adsorbent tubes for sampling trace level of hydrogen sulfide was quantified. A thermal desorption -gas chromatographic analytical method was developed for the separation and accurate quantitative analysis of hydrogen sulfide collected simultaneously with other red
