ANALYZING DEVICE FOR LIQUID CHROMATOGRAPHY COMPRISING A MOBILE PHASE FEEDER AND A STORAGE CONTAINER FOR MOBILE PHASE

摘要

A liquid chromatography device A includes a column 1 containing a filler, an injection valve 4 capable of introducing a sample into the column 1 and also capable of introducing a liquid mobile phase into the column 1, and a mobile phase feeder 3 for feeding the liquid mobile phase from a mobile phase container B containing the liquid mobile phase to the column 1 via the injection valve 4. Between the mobile phase container B and the injection valve 4 is provided a storage chamber 5 for temporarily storing the liquid mobile phase sent from the mobile phase container B. The device further includes a liquid level detection sensor for detecting the liquid level of the liquid mobile phase in the storage chamber 5. This structure allows the liquid for use in analysis to be used completely without being wasted.
