GC AND GC/MS - Your Essential Resource for Columns & Supplies

Essential Gas Chromatography and GC/MS Supplies for Reliable Trace-Level Analysis

Význam tématu

Gas chromatography (GC) and GC coupled to mass spectrometry (GC/MS) remain foundational analytical techniques across environmental, food, pharmaceutical and forensic laboratories. Achieving low detection limits, robust quantitation and consistent retention times demands not only high-performance instruments but also rigorously controlled columns, inlet liners, seals and accessories. Advances in inert flow paths and low-bleed consumables directly impact sensitivity, reproducibility and instrument uptime, especially for active or labile analytes at trace levels.

Hlavní výsledky a diskuse

Performance testing demonstrates:

• Ultra Inert liners with glass wool maintain analyte recovery and reproducibility across hundreds of injections, reducing endrin breakdown compared to standard liners
• Touchless packaging speeds liner replacement and eliminates contamination from manual O-ring handling
• Self-Tightening nuts maintain column seals through thermal cycling, reducing re-tightening and leaks
• High-temperature headspace septa yield minimal bleed and background at 300 °C, improving trace VOC analysis
