We offer gas chromatography columns to separate and analyze complex mixtures of chemical compounds for a varierty of gas chromatography applications in analytical chemistry labs. Experience precise compound differentiation and identification with our range of advanced GC columns. We offer two main types of GC column formats: capillary and metal columns. Our capillary GC columns are made of fused silica, and we have application-specific proprietary phases for food, environment, forensic, pharmaceutical, fuel, studies. Our metal columns utilize an innovative bonding method known as Glass Infusion Technology which guarantees thorough coverage of the exposed metal, enhancing the efficiency, recovery, and quality of gas chromatography peaks in the column's performance to be used with high temperature applications. Our metal columns utilize a gas chromatography split ratio of 100:1 for faster run times and offering high throughput.

FAQs
What is the difference between gas chromatography and high-performance liquid chromatography?
Gas chromatography (GC) employs an inert carrier gas as the mobile phase, making it ideal for separating volatile compounds, while high-performance liquid chromatography (HPLC) uses a liquid mobile phase, offering versatility for a wide range of compounds, including polar and non-volatile substances. We provide advanced columns for gas and high-performance liquid chromatography.
How do I choose the right column for gas chromatography?
When selecting a column for GC, it's crucial to assess the range of compounds you'll be analyzing, as different column phases suit varying compound types. Also, consider analysis time – shorter columns offer faster results, but longer columns provide higher resolution. Fused silica glass tubes are commonly used due to their inertness and wide temperature range. The column material, whether glass or stainless steel, affects performance and susceptibility to contamination. If you're looking for high separation efficiency, consider wall-coated open tubular (WCOT) columns, which consist of a capillary with the inner wall of the capillary coated for improved resolution and speed. GC accessories like inlet liners and detectors impact performance, so ensure compatibility. Our innovative column solutions are designed to align with these considerations seamlessly.
