  • Method and apparatus for monitoring fluid flow
    Publication number: 20040237627
    Abstract: An apparatus for monitoring fluid flow within a high pressure liquid chromatography system. The apparatus includes a pump for supplying a system flow of eluent to the system, a chromatography column, a flow splitting device having a first restrictor fluidly connecting the pump and the chromatography column, a second restrictor fluidly connecting the pump to a waste line, a first fluid pressure sensor monitoring a system fluid pressure upstream of the first restrictor, and a second fluid pressure sensor monitoring a column fluid pressure downstream of the first restrictor. A method of using the apparatus for fluid flow control is also disclosed.
