Pseudo-absolute quantitative analysis using gas chromatography - Vacuum ultraviolet spectroscopy - A tutorial.

Area of Science:

• Analytical Chemistry
• Spectroscopy

Background:

• Gas chromatography (GC) is a widely used separation technique.
• Accurate quantification in GC often relies on external or internal calibration standards.
• Traditional calibration methods can be time-consuming and introduce their own sources of error.

Conclusions:

• The VUV detector's pseudo-absolute quantification capability provides a novel approach for GC system performance evaluation.
• This method can address challenging quantitative analytical problems by minimizing reliance on calibration standards.
• An internal standardization approach can be integrated with the pseudo-absolute method for practical quantitative analysis, normalizing systematic errors.
