Abstract

Systems and methods for inline and automatic dilution of chemicals of interest for speciation and subsequent analysis by ICP spectrometry are described. A system embodiment includes a first valve to receive a sample into a holding loop; a plurality of syringe pumps coupled to the first valve to deliver an inline diluted sample from the first valve; and a second valve coupled to the first valve to receive the inline diluted sample from the first valve into a sample holding loop coupled to the second valve, the second valve configured to couple to at least one of an eluent source or a carrier fluid source to receive at least one of an eluent fluid or a carrier fluid to transfer the inline diluted sample from the sample holding loop to a speciation column to separate one or more species from the inline diluted sample.
