[0002] Chromatographic column is an important tool in chemical analysis, mainly used for separating and purifying different components in a mixture. During the chromatographic analysis process, sample components will accumulate on the chromatographic column, especially on silica gel chromatographic column. These accumulated samples and impurities will gradually form a new stationary phase, affecting the separation effect and retention time of the chromatographic column. Therefore, the chromatographic column needs to be cleaned.
