Extending the Amount Fraction Range of Organic Mixed Standard Gases Using Post-Column Reaction GC

Key Points

• The aim is to develop methods for accurately quantifying organic compounds in gases using standard gases.
• Used gas chromatography (GC) to separate target compounds and convert them to methane via post-column reaction.
• Developed a calibration curve extension method using two types of volumetric tubes with different volumes.
• Combined both methods to enhance the quantification range of standard gases.
• Achieved successful quantification of multiple target compounds from specific standard materials.
• Extended the calibration range for standard gases to match various concentrations without extrapolation.
