Abstract
To provide a degassing unit having a wide range of flow speed, high-efficiency compactness in size, this degassing unit consists of both a degassing module composed of a gas permeable flat-shaped tube 201 wound around the internal vacuum space 401 and a vacuum chamber containing this flat tube, and by flowing an eluent through the flat tube 201 which constitutes the degassing module, gaseous components dissolved in the eluent can be transpired from the flat tube 201 to the vacuum chamber accommodating the internal vacuum space 401 and the external vacuum space 402 and 403, thus being well removed.
Claims3
In a degassing unit for high performance liquid chromatography installed between an eluent delivery pump and an eluent reservoir in order to remove gaseous components dissolved in eluent which is drawn from a reservoir by the eluent delivery pump and deliver the degassed eluent to a detection means including a separation column via a sample injection valve, the degassing unit consisting of both a degassing module composed of a gas permeable flat-shaped tube and a vacuum chamber containing this flat tube, and the degassing unit being characterized by such that by flowing said eluent through said flat tube which is a component of the degassing module, gaseous components dissolved in the eluent can be transpired from the flat tube to the vacuum chamber, thus being well removed.
