Automated Acid Digestion Unit


Automated Acid Digestion Unit

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.


Research Facility

Cosmic Ray Isotope Science at Dal Lab (CRISDal Lab)
Dalhousie University
Nova Scotia (NS)

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.
