Thermo Scientific™ TraceGOLD™ TG-624SilMS GC Columns, 1.4μm film thickness, 0.25mm I.D., 30m length

The Thermo Scientific™ TraceGOLD™ TG-624SilMS GC Column is a premium mid-polarity capillary column engineered for high-performance analysis of volatile organic compounds (VOCs), residual solvents, alcohols, and oxygenated compounds. Featuring a 1.4 μm thick film, 0.25 mm internal diameter, and 30 m length, this column delivers exceptional retention and separation of highly volatile analytes, making it ideal for pharmaceutical, environmental, petrochemical, and forensic GC/MS applications.

Built with the advanced TraceGOLD™ TG-624 SilMS stationary phase, which is chemically equivalent to 6% cyanopropylphenyl / 94% dimethylpolysiloxane, the column provides superior inertness, minimal bleed, and excellent peak symmetry. Its low-bleed design enhances sensitivity and reproducibility, particularly in GC/MS systems where stable baselines and low detection limits are essential.

Equivalent to USP G43 and comparable to industry-standard columns such as DB-624, VF-624ms, CP-Select 624 CB, and ZB-624, the TG-624SilMS is a trusted choice for regulated laboratories and high-precision analytical workflows.
