Capabilties of the Nutrient Analysis Lab

The Nutrient Analysis Lab has the ability and infrastructure to perform the following analyses:

  • Elemental analysis of major nutrients and metals by inductively coupled plasma optical emission spectroscopy. Microwave digestion and digestion blocks are available for use.
  • Simultaneous analysis of ammonia, ortho-phosphate, nitrate, and nitrite from water samples, soil extracts, and plant tissues by a multi-channeled flow-through Lachat system.
  • Total Kjedahl nitrogen analysis of water samples, soil extracts, and plant tissues using a flow-through Lachat system. Associated digestions blocks are available for use.
  • Other colorimetric analyses by microplate reader. These include ammonia, nitrate, nitrite, silica, chloride, and ureides, among others.
  • Total nitrogen and total phosphorus analysis of plant tissues using a dual channel flow-through system. Digestion manifolds are available.
  • Carbon analysis of water samples and soil extracts by catalytic oxidative combustion using a Total Organic Carbon analyzer.
