GC Injectors

GC injectors are critical components in gas chromatography systems, designed to introduce samples into the chromatograph for high-precision analysis. They typically handle sample volumes ranging from 0.1 to 5 microliters, ensuring accurate and reproducible results. Split/splitless injectors, the most prevalent type, can achieve split ratios up to 1:1,000, allowing for flexible handling of sample concentrations. These injectors operate at temperatures up to 450°C and pressures between 0.1 and 10 bar, facilitating the injection of volatile and semi-volatile compounds. Advanced models feature programmable temperature vaporizing (PTV) capabilities, offering precise control over sample vaporization and ensuring minimal degradation. With injection repeatability often within 1 percent relative standard deviation (RSD), GC injectors are essential for reliable chromatographic performance and high-quality analytical results.
