CRISDal Lab is a state of the art geochemistry facility with isotope-specific wet chemistry laboratories to prepare targets for accelerator mass spectrometry, labs for digestion of silicate rocks or powders, a low-level radiocarbon-extraction laboratory for cosmogenic 14C in quartz, an inductively coupled plasma optical emission spectrophotometer (ICP-OES) and labs for mineral separation, ion chromatography by column chemistry.

Measures the concentrations of elements (not isotopes) in solution at levels above 0.1 ug/ml.
Radial torch system, with CETAC autosampler.
Prodigy Model is labeled 'Special' because it is adapted to measure halogens, and it uses a mass flow controller to deliver the Ar torch gas, which ensures higher measurement precision.
The ICP-OES is typically available for same week measurement of one or more major or minor elements if samples are received in solution form. If in solid form, and digestions are required, or if new standards are required for elements that we don't routinely measure, it may take longer.
We routinely provide error analysis and match matrices of the standards to the samples. Typical elemental precisions are better than 2%. We can provide dilution series, standard addition, and internal standards upon request.
This lab is not ISO certified, but forms a component of a geochronology laboratory that requires a high level of precision that vastly exceeds ISO uncertainty requirements.
In 2018 we will be hiring a full time technician to shorten wait times.
This is a 72-inch perchloric acid digestion laboratory with non-plasticized PVC washdown ducting, in an isotope geochemistry lab. Suitable for perchloric and hydrofluoric acids, among others.
72" with air flow monitor, electrical duplexes on separate circuits for multiple hotplates
To digest silicates or disolve solids, dilute them, and transfer aliquots to test tubes
The programmable Vulcan is an automated and enclosed instrument that uses shringes and a peristaltic pump to transfer HF, HNO3, and other acids or solutions to 48 teflon digestion vessels, automatically lowers the mixture into a heat block to heat to 200C, blows air to periodically mix the mixture during digestion, raises the vessels, brings the solution up to a calibrated volume, and precisely transfers an aliquot of the solution in each vessel to one or more test tubes for ICP-OES or other analysis.
To separate minerals on the basis of there physical processes
Heavy liquid separatory funnels
Frantz isostatic magnetic separator
Ultrasonic tanks (include NEY models, up to 25 gallon)
Froth flotation systems
