Capillary column connector

A capillary column connector comprising:

• a metal connector main body comprising:
• a first column installation port into which a first capillary column is inserted, a second column installation port into which a second capillary column is inserted,
• an internal space, in which are arranged the tip of the first capillary column that has been inserted from said first capillary installation port and the tip of the second capillary column that has been inserted from said second capillary installation port, and
• a gas supply route that is connected to said interior space, and
• a metal tubular member movable in and out of the aforementioned internal space, and
• wherein with the tip of the first capillary column inserted from one end of said tubular member and the tip of the second capillary column inserted from the other end of said tubular member, the tubular member is arranged in said internal space, and the gap between the internal peripheral surface of one end of said tubular member and the outer peripheral surface of the first capillary column as well as the gap between the internal peripheral surface of the other end of said tubular member and the outer peripheral surface of the second capillary column are purged with gas from said gas supply flow path.
