Abstract: Methods for extracting an analyte from a sample through a gas preparation system comprise supplying gas and liquid solvent which solvent can dissolving the analyte in the sample to the sample cell; receiving the liquid solvent containing the analyte from the extraction module to the evaporation container; evaporating the liquid solvent containing the analyte in the evaporation container, wherein the evaporation module is in fluid communication with the sample cell; and starting to perform the evaporating step is allowed after at least a part of the liquid solvent containing the analyte from the extraction module enters the evaporation container. The method integrates extraction and evaporation together to allow “evaporation/concentration online”, thereby avoiding the transfer process of the analyte, saving labor, increasing processing speed, and avoiding the risk of contamination. A gas preparation system for extracting an analyte from a sample is also provided.

Abstract: A test lead assembly includes a first test lead having a first cable extending between a distal end and a proximal end, a first test probe attached to the distal end and a first plug attached to the proximal end; a second test lead having a second cable extending between a distal end and a proximal end, a second test probe attached to the distal end, and a second plug attached to the proximal end; and a fastener member for repeatedly releasably engaging at least a portion of the first cable with at least a portion of the second cable along a length of the first and second cables. The test lead assembly and a measurement device incorporating the test lead assembly can avoid or at least reduce knotting of the test leads.
