Laboratory Services<\/h2>\n\nIn 2017, with generous support from the M.J. Murdock Charitable Trust, WSU Vancouver established the Water Chemistry Facility, a state-of-the-art water chemistry laboratory equipped with an Agilent 7900 ICP MS, a DIONEX Ion Chromatograph, and a Hach Dissolved Organic Carbon and Total Nitrogen Analyzer. Together, these instruments can be used to detect and quantify a broad range of elements and ions. In addition to its own research, the facility also offers its services to researchers, governmental users, and the private sector.<\/p>\n

Our Agilent 7900 ICP-MS uses a high-temperature argon plasma torch\u00a0to\u00a0ionize atoms\u00a0in samples. Once ionized, sample\u00a0atoms\u00a0are routed through a mass\u00a0spectrometer,\u00a0which separates\u00a0and detects\u00a0sample constituents\u00a0according\u00a0to their\u00a0mass and charge. The Agilent 7900 has a dynamic solution\u00a0concentration range due to argon dilution capabilities, making it possible to run samples in the ppm\u00a0range as well as very low (below parts per trillion) levels for trace elements.<\/p>\n![](\"https:\/\/wpcdn.web.wsu.edu\/wp-vancouverlabs\/uploads\/sites\/2136\/2018\/06\/pasted-graphic-1.jpg\")

Ion chromatographs (ICs) separate anions by pushing them onto a selectively retentive exchange column, eluting them sequentially, and measuring the change in conductivity as anions pass through a detector. The ThermoFisher Integrion IC in our facility (shown above) allows for the simultaneous determination of concentrations of anions such as fluoride, chloride, nitrite, bromide, nitrate, sulfate, and phosphate at parts-per-billion levels, and with pre-concentration can measure these compounds down to parts-per-trillion levels. Additionally, this IC can be used to test for disinfectant by-products, such as bromate in tap or bottled water, perchlorate and haloacetic acids in drinking water, iodide and iodate in seawater, amines in wastewater, and more.<\/p>\n<\/div>\n![](\"https:\/\/wpcdn.web.wsu.edu\/wp-vancouverlabs\/uploads\/sites\/2136\/2018\/09\/pasted-graphic-3-2.jpg\")
