Columbia Analytical Offers New Micro-Elemental Test for Oxygen


Columbia Analytical Tucson Laboratory is excited to announce the arrival of their new LECO TruSpec Carbon, Hydrogen, Nitrogen, Sulfur (CHNS) Analyzer with Oxygen Module and Auto Samplers.

The addition of this new equipment will enable Columbia Analytical to increase capacity for CHNS analyses and analyze difficult matrices for oxygen.

“We can analyze CHNS on a single aliquot of sample, thus reducing the amount of the sample needed. Oxygen analyses can also be performed on organo-metallic samples and samples containing fluorine,” stated Lab Manager Ralph Poulsen. “The instrument is easily switched from CHNS to oxygen and stabilizes within an hour versus up to a day with other instruments.”

TruSpec analyzers operate at a higher pyrolysis temperature (1,250 vs 950C) which is critical in breaking organo-metallic and oxygen bounds and it uses IR detectors which eliminates the need for a gas separation column that is easily poisoned by low concentrations of fluorine in the sample.

“Oxygen analyses times will be greatly improved from approximately five to six minutes to less than two minutes,” said Poulsen. “This new analyzer also supports compliance to FDA Regulation 21 CFR Part 11 and AOAC, AACC, AOCS, ASBC and ASTM approved methods of analyses.”
