Sampling a fluid to determine its contaminant content
A method of sampling contaminant concentrations in a fluid medium includes diluting a sample withdrawn from the fluid medium, e.g. air, into a housing 1 with an inlet 6 for a dilution fluid e.g. clean air. The diluted sample thence passes into a mixing chamber 8 for deposit on or in a collection med...

| Zusammenfassung: | A method of sampling contaminant concentrations in a fluid medium includes diluting a sample withdrawn from the fluid medium, e.g. air, into a housing 1 with an inlet 6 for a dilution fluid e.g. clean air. The diluted sample thence passes into a mixing chamber 8 for deposit on or in a collection medium 14 for analysis, the fluid being drawn through the housing 1 by a pump 18. Process is especially of use at high contaminant concentrations. Suspended particulates in H2O samples can also be determined. |
