Automatic capillary replacement system

An automatic capillary replacement system comprising:

• a base on which a clamping loader having a clamping part which clamps a capillary at a leading end is to be detachably mounted;
• a main stage disposed on the base such that the main stage is to reciprocate horizontally along an X axis;
• a sub-stage disposed on the main stage such that the sub-stage is to reciprocate horizontally along a Y axis that intersects the X axis;
• a capillary mounting unit mounted on the sub-stage such that the capillary mounting unit is to reciprocate horizontally in a Z-axis direction, wherein a new capillary to be supplied is mounted on the capillary mounting unit;
• a capillary collecting/supplying unit having a capillary clamper which is movable on the main stage in each of the X, Y and Z axes;
• an unclamping unit disposed on the sub-stage, wherein the unclamping unit selectively releases the clamping part of the clamping loader so that the capillaries can be separated and mounted;
• a first drive part which causes the main stage to reciprocate;
• a second drive part which causes the sub-stage to reciprocate;
• and
• a third drive part which causes the capillary collecting/supplying unit along the Y axis.
