You can find the related application note from the following site.

To connect the retention gap column between the pump mixer and the injection valve,
One pipe (part number: 430002452) is required.

Use the retention gap column and the analytical column in a 30cm column heater.

Although it is possible to use a retention gap column at room temperature,
it may be necessary to set a low flow rate during the analysis since the pressure becomes high.

Also, for vial cap we recommend to use the following:

Polypropylene vial with PE septumless cap, part number 186004112 and 186005230.
