Abstract:
A method for analyzing metal in a fluid comprising:a) providing a fluid comprising solid metal particulates and gaseous metal;b) supplying a continuous filter media substrate;c) maintaining a first portion of said filter media substrate at a temperature coinciding with the phase in which the metal is to be analyzed in order to condense the gaseous metal to be analyzed and thereby simultaneously collecting solid metal particles and gaseous metal;d) contacting the fluid to the first portion of said substrate to retain the metal in the form of solid metal particles and condensed gaseous metal on the first portion of said substrate;e) preventing further contact of the fluid to the first portion of substrate; andf) contacting the fluid to a second portion of said substrate to retain metal on the second portion of the said substrate while simultaneously analyzing the first portion for metal, whereby the second portion of said substrate is integral to the first portion of said substrate.
