Flame Ionization Detector Supplies

Flame Ionization Detection (FID) remains the most widely used GC detection technique due to its exceptional sensitivity for hydrocarbons and broad linear dynamic range. In an FID system, analytes are ionized within a hydrogen–air flame, and the resulting ion current is measured to quantify the amount of material combusted—providing fast, stable, and highly reproducible detection across a wide range of applications.

Chrom Tech supplies the complete line of genuine Agilent FID components needed to maintain precise detector performance. This includes igniter glow plugs, collector nuts, cleaning and maintenance kits, and Agilent’s advanced single-piece FID jets designed for easier installation, reduced thread damage, and improved analytical consistency. All supplies are OEM-engineered to support long-term reliability and high-quality chromatographic results.
