The internal volume of HPLC tubing varies with its diameter and length. For instance, a 1/16-inch tubing with a 30 cm length may have an approximate internal volume of around 0.006 mL, while a 1/4-inch tubing with the same length may have a volume of approximately 0.096 mL. These values are crucial for accurate sample injection and chromatographic analysis in HPLC systems.
