High performance liquid chromatography typically uses various organic reagents as the mobile phase, which is stored in a mobile phase bottle, and the liquid chromatograph is stopped when the liquid level of the mobile phase is below a certain level. In order to avoid the liquid phase from stopping running, experimenters add excessive mobile phase into a mobile phase bottle, but the mobile phase generally needs to be newly prepared or used in a short time, so that the operation causes the waste of the mobile phase, and particularly for organic reagents, the price is more expensive.
