Abstract
A high-pressure capillary degas assembly includes an assembly block having an eluent inlet and an eluent outlet, and a separator support extending therebetween, a wash inlet and a wash outlet and a groove extending therebetween, a tubular separator extending within the assembly block, the separator having an inner surface and an outer surface, the inner surface defining an eluent fluid line fluidly interconnecting the eluent inlet and outlet, the outer surface abutting against the separator support and enclosing the groove to define a wash line within the groove. The separator may be configured to retain liquid in the eluent fluid line at a first pressure and allow gas to flow through the separator to the wash fluid line at a second pressure lower than the first pressure. A method of using the high-pressure capillary degas assembly is also disclosed.
