Microwave plasma detector

Sakamoto et al. [626] demonstrated the application of the microwave plasma detector to the analysis of trace amounts of aluminium and copper in zinc by GC in the form of their volatile chelates. A column packed with 0.5% of SE-30 on glass beads was used at 140°C. With the same chelates as above, the detection limit was 1 ng for copper and 0.5 ng for aluminium.

Reamer et al have discussed the applicability of a gas chromatograph coupled with a microwave plasma detector (GC-MPD) for the determination of tetraalkyllead species in the atmosphere. The tetra-alkyllead species are collected by a cold trap. The volatile lead species are concentrated within an organic solvent, separated by a gas chromatographic column and determined by an MPD system which measures the emission intensity of the lead 405.78 nm spectral line. Previous workers have used an acidic solution of hydrochloric acid > activated charcoal , Apiezon L on a silanized universal sup-port the chromatographic support OV-1 and silicone rubber on Chromosorb to collect alkyllead compounds from the atmosphere.
