Gas chromatography column and supplies

Gas chromatography (GC) is a cornerstone of analytical chemistry, enabling the separation and analysis of compounds that can be vaporized. This technique is used across many industries, from pharmaceuticals to environmental testing, for accurate and efficient chemical analysis.

Choosing the right gas chromatography supplies is essential for achieving reliable results. Every component—from columns to inlet liners—plays a critical role in the accuracy and efficiency of your GC system.

As an authorized distributor, Chrom Tech provides high-quality GC columns and supplies from trusted brands like Agilent, Restek, and Trajan/SGE. These brands are known for precision, durability, and consistent performance in demanding lab environments.

Understanding Gas Chromatography and Its Importance

GC separates complex mixtures into individual components for both qualitative and quantitative analysis. It’s valued for its sensitivity, speed, and ability to handle complex samples. Industries like food safety, pharmaceuticals, and environmental science rely on GC for accurate results.

• High sensitivity for trace-level detection
• Fast analysis times compared to other analytical methods
• Capability to handle complex chemical mixtures efficiently

Key Components of Gas Chromatography Equipment

• Columns: Where separation occurs.
• Detectors: Identify and quantify compounds as they elute from the column.
• Injectors: Introduce precise sample volumes.
• Carrier gas systems: Maintain stable flow for consistent operation.

Gas Chromatography Columns: Types and Leading Brands

GC columns are central to successful separations. Capillary columns provide high resolution for complex analyses, while packed columns handle larger sample volumes. Selecting the right column type is critical for optimal results.

Leading brands such as Agilent GC Columns and Restek GC Columns provide precision-engineered solutions designed for stability, reproducibility, and long service life.
