How to Choose the Best Chromatography Fittings
Material Compatibility
The material of your chromatography fittings must be compatible with the solvents and mobile phases you use. Common materials include stainless steel, PEEK, and PTFE. Stainless steel offers excellent chemical resistance for many applications, while PEEK is ideal for aggressive solvents and high-pressure systems. PTFE is suitable for very corrosive environments.
Connection Type and Size
Ensure the fittings match the threads and dimensions of your chromatography system components, such as columns, pumps, and detectors. Common thread sizes include 1/16", 1/8", and 1/4". Verify whether you need male or female fittings and the appropriate ferrule type (e.g., compression ferrules) for a secure and leak-free seal.
Pressure and Temperature Ratings
Chromatography often involves high pressures and varying temperatures. Select fittings rated to withstand the maximum operating pressure and temperature of your specific application. Exceeding these ratings can lead to leaks, component failure, and inaccurate results.
