摘要:
An improved apparatus to remove gases (or a particular gas) from a sample prior to detection of the sample. The apparatus and method is useful in the removal of gas from the mobile phase in a detection and analysis apparatus.
摘要:
An apparatus and method for electrochemically modifying the retention of a species on a chromatography material is disclosed. The apparatus comprises a housing (1) having an effluent flow channel (9) adapted to permit fluid flow therethrough. The effluent flow channel (9) comprises chromatography material (15). The apparatus further comprises first and second electrodes (11, 13) positioned such that at least a portion of the chromatography material (15) is disposed between the first and second electrodes (11, 13), and fluid flow through the apparatus is between, and in contact with, the first and second electrodes (11, 13).
