The document introduces the features and performance of Agilent J&W Ultra Inert Capillary GC Columns. It offers a higher and more consistent level of inertness, allowing for trace level analysis and unknown sample screening with reliable results.
Agilent Technologies presents the J&W Ultra Inert GC capillary columns as a solution for analyzing challenging analytes such as acids, bases, and drugs. The document emphasizes that these columns offer consistent column inertness and exceptionally low column bleed, which are critical for trace-level analysis and unknown sample screening.
The brochure details Agilent's rigorous testing methodology using the 'Uber One Test Probe Mixture' to validate performance against competitors. It explains how active compounds can cause peak tailing and adsorption on non-inert columns, leading to inaccurate results, whereas Ultra Inert columns provide symmetrical peaks and reliable quantification.
They are the only GC columns proven to deliver consistent column inertness and exceptionally low column bleed.
Active compounds such as acids and bases will exhibit severe peak tailing, leading to inaccurate quantification.
The column might eat up the very compounds you are trying to analyze, so the amount injected is not the same as the amount that reaches the detector.
