Hello,

I research tubes to put instead of the columns to measure different pressure in is HP1100. Could you please indicate me what tubes it's make for that?

Thanks,
Phenol

Hi Phenol,

Hello Delphine,
The only way I know for mesuring system pressure is to put an union like PN0100-0900 without void volum instead of the column.
There are different metal connector version available. Metal connector 5061-5801 is used to connect to columns with each other like a retention gap. A single Vespel ferrule is used to connect both capillaries.
5182-0744 use a Quartz insert in the metal housing. Special Vespel ferrules need to be ordered for the 2 column dimensions that need to be connected. There´s no ferrule to connect tubing of 0.25 to 0.32mm
