What are GC injectors used for?
GC injectors are used to introduce samples into gas chromatography systems with high precision. They ensure accurate and reproducible results by handling small sample volumes efficiently.
What types of samples can GC injectors handle?
GC injectors are designed to handle volatile and semi-volatile compounds across various concentrations.
What is the volume range for sample injection?
GC injectors can handle sample volumes ranging from 0.1 to 5 microliters.
What is the operating temperature range?
GC injectors can operate at temperatures up to 450°C, allowing them to vaporize samples efficiently.
What is the pressure range supported by these injectors?
They can operate within a pressure range of 0.1 to 10 bar.
What is a split/splitless injector, and when should I use it?
Split/splitless injectors allow flexibility in handling different sample concentrations by adjusting split ratios up to 1:1,000. Split mode is ideal for concentrated samples, while splitless mode is used for trace-level analysis.
What is programmable temperature vaporizing (PTV), and why is it beneficial?
PTV allows precise control over the sample vaporization process by adjusting the injector’s temperature program, optimizing the analysis of thermally sensitive or diverse compounds.
How reliable is injection with these injectors?
GC injectors provide high injection repeatability, ensuring consistent and reliable chromatographic performance.
Can these injectors be used in different types of gas chromatography systems?
Yes, GC injectors are compatible with various gas chromatography systems and applications, ensuring versatility.
Are these injectors suitable for both research and industrial applications?
Yes, GC injectors are designed for diverse applications, making them ideal for research, quality control, and industrial analysis.
