I want to connect the transfer line of G1888 to the carrier gas tubing of injection port of G6890. But the union I have isn't correct. I guess the nut of carrier gas tubing from injection port is 1/16 inch. But the end of transfer line is a metric male nut. Could anybody tell me where I can buy the zero dead volume union with two different female connectors? And the part number too. Thanks

Hello
It is easier to cut tip of HS transfer line and install 1/16 nut.
Just remember to connect transfer line very close to GC inlet to avoid "cold spot".

Agilent has a part number to enable the M5 nut on the HSS transfer line to connect to 1/16 tubing. Part number is G3521-80000
