Use of Carbon Dioxide to Calibrate Instrument for Determination of Carbon Below 50 Parts per Million in Metals

Abstract

In the determination of carbon below 50 parts per million organic compounds have been used for calibration in the absence of suitable metallic standards. The addition of gaseous carbon dioxide (CO2) as a calibration technique is proposed. A comparison of standardizations with an organic compound and with CO2 additions is presented. A significant improvement in the precision of a calibration curve by using CO2 is demonstrated.
