Gas chromatography (GC) systems separate and analyze molecules by introduction into a continuous gas stream, followed by column separation and detection by flame ionization or another technique. The systems are widely used in analytical labs, biomedical research, materials science and a host of other fields. Important considerations include: the type and robustness of gas injectors, the configuration and ease with which to adjust pre-columns and separations columns, and the type and quality of detectors. The user interface and data analysis software are important aspects as well, with a range of advanced options available with newer systems. How Much Does a GC system Cost? The typical price of a new GC system costs in the range of $10,000 - $75,000, whereas a used GC system ranges in price from $2,500 - $40,000
