GC Sample Introduction

Gas chromatography (GC) sample introduction systems are specialised instruments and accessories designed to enable the accurate transfer, concentration, and preparation of samples prior to chromatographic analysis. They play a critical role in ensuring reproducible injection, efficient trapping or desorption of target compounds, and reliable delivery of gaseous, liquid, or thermally extracted analytes into the GC system. Commonly used in environmental, petrochemical, pharmaceutical, and industrial laboratories, these technologies support the analysis of trace-level contaminants, volatile and semi-volatile organic compounds, and complex air or process samples. By improving sensitivity, minimising sample loss, and enhancing workflow consistency, GC sample introduction solutions form an essential part of modern analytical instrumentation setups.
