The liquid chromatograph "Lumachrom-M" provides maximum automation of the analysis. The device is controlled using specialized software, which in combination with the continuous eluent supply mode and the autosampler gives the maximum level of autonomy of operation. In addition, such a solution minimizes labor costs and the influence of the human factor. The unique design solutions of the chromatograph provide continuous pulsation-free flow of the mobile phase in both isocratic and gradient modes, as well as the ability to work with any column sizes. Thanks to the improved technical characteristics on the Lumachrom-M device, it is possible to implement a wider list of techniques and GOST compared to previous models.
