Method and apparatus for analyzing acrylamide |
| abstract |
An object of the present invention is to allow foreign substances in a sample solution to be more effectively retained, and to allow acrylamide to be eluted and detected under the influence of the foreign substances. An ODS column 2 and NH 2 columns 4 are connected in series as a separation column. A liquid sending pump 8 is provided to supply water 6 as a mobile phase to the upstream column 2, and an injector 10 for injecting a sample solution is arranged in a flow path between the liquid sending pump 8 and the column 2. ing. A liquid feed pump 14 for supplying acetonitrile 12 is connected to the connection between the columns 2 and 4 in order to join another solvent different from the mobile phase 6 as a mobile phase. A mass spectrometer is connected as the detector 16 to detect the eluate in the column 4 on the downstream side. [Selection diagram] Fig. 1 |
