| 摘要 |
A liquid phase chromatograph having an on-line cleaning function, comprising a first flow channel (L3), a second flow channel (L21), an analysis flow channel (L22), a waste liquid flow channel, a cleaning flow channel (L25), a direction switch valve (V1), a multi-flow channel switch valve (V2), etc. The liquid phase chromatograph changes the liquid flow path by changing the communication relationship between the two-position switch valves, which achieves the on-line cleaning function for a first chromatographic column (C1), a middle chromatographic column (C2), a filter or a protector (B2) respectively and can perform on-line cleaning on the first chromatographic column (C1) and the middle chromatographic column (C2) simultaneously. |
