Electrochemical detection of particulates in a gaseous sample using potentiometric measurements in a gaseous flame electrolyte

摘要

The present invention provides a method for the detection of particulates in a sample, wherein the particulates are introduced into a plasma and the potential difference between a common electrode and each of a plurality of indicator electrodes is measured. The invention further provides an electrode array and an apparatus which can be used for the potentiometric detection of particulates in a sample.
