Tubing on a nano-liquid chromatography (nano-LC) technique, used for really very low circulation capacities The inner diameter (ID) of the HPLC column is an important parameter.[44] It could affect the detection reaction when reduced as a result of reduced lateral diffusion in the solute band. It might also impact the separation selectivity, when circulation price and injection volumes are not scaled down or up proportionally to your lesser or bigger diameter made use of, both of those from the isocratic As well as in gradient modes.
