The separation column is at the heart of analytical precision. We manufacture, condition and test our columns in our own laboratories so you can be sure that your peaks will be separated perfectly time after time. All columns are conditioned and supplied with test documentation and chromatograms which provide peak resolution and retention time under typical running conditions. All OEA Labs columns are suitable for Elemental Analysis (EA) and Isotope Ratio Mass Spectrometry (IRMS) applications. If you need a column that is not listed please contact us.
