Our Work

The Water Sciences Laboratory has been providing professional services to businesses, academic researchers, and government entities since the early 1990s. Our client-base is diverse - just as the projects we are involved with.

The Water Sciences Laboratory (WSL) was established as a core research facility at the University of Nebraska-Lincoln as part of the Nebraska Water Center in 1990. The facility was created to enhance and support NU water research as a state-of-the-art laboratory that could provide technical services and expertise in analytical and isotopic methods.

To this end, WSL provides specialized instrumentation and methods for organic contaminants, heavy metals and for stable isotope mass spectrometry. WSL ’s faculty, staff, and students have analyzed thousands of samples at the facility over the past 25 years.

The WSL currently boasts about $2.5 million in analytical equipment and a staff that includes a director and four full-time technical staff.

Environmental Mass Spectrometry

The Water Sciences Laboratory specialize in environmental mass spectrometry and chromatography for the detection and quantification of chemical contaminants including new groups of pesticides, as well as emerging microcontaminants such as antibiotics, veterinary pharmaceuticals and steroid hormones. A few of the newer methods that have been developed include:

  • Steroid hormones and mycotoxins by liquid chromatography tandem mass spectrometry LC/MS/MS – APPI
  • Microcystins and cyanoneurotoxins (anatoxin-a, BMAA, saxitoxin, cylindrospermopsin) by LC/MS/MS
  • Veterinary antibiotics in water, soil, and passive samplers by LC/MS/MS
  • Municipal and domestic wastewater (caffeine, carbamazepine, methamphetamine, and others) by LC/MS/MS

Stable Isotopes

The Lab offers state of the art methods for stable isotope analysis of gases water and solids using stable isotope mass spectrometry.

  • Nitrate (15N-NO3 and 18O-NO3)
  • Phosphate (18O-PO4)
  • Ammonia (15N-NH3)
  • Water (HD and 18O-H2O)
  • Helium-3/4 in ground water by noble gas mass spectrometry, including N2, Ar, Ne, Kr and Xe

Standard testing methods

Finally, the lab also offers a relatively complete set of nutrient and water chemistry methods such as:

  • Nitrogen (TN, TKN, TDN, NO3, NH4)
  • Phosphorus (TP, TKP, TDP, O-PO4)
  • Major ions (anions and cations)
  • Trace elements by ICPMS
  • General water chemistry (pH, conductivity, dissolved oxygen)
  • Total suspended, dissolved, and volatile solids (TSS, TDS, TVS)
  • Microcystins by ELISA
  • Chlorophyll by HPLC
  • Biological and chemical oxygen demand

We even have ASBC methods for hops testing, including α-acids and β-acids, and hops storage index (HSI)!

Our available methods are constantly being updated. However, if you have a custom-application not currently listed, contact us and we can discuss method development.
