| 20110005304 | FLOW CONTROL IN HIGH PERFORMANCE LIQUID CHROMATOGRAPHY - A method for controlling the flow of liquid in a high performance liquid chromatography apparatus. The method includes operating a pump, measuring the liquid pressure downstream of the pump, measuring the liquid flow rate downstream of the pump, and controlling the operation of the pump. In the method, it is automatically determined whether the pump is controlled to achieve a desired pressure or controlled to achieve a desired flow rate. Fuzzy logic can be applied in the method to determine the switch between the control modes. | 01-13-2011 |
| 20090145203 | PLUGGED FLOW 2D CHROMATOGRAPHY - The invention provided is a split-free nano-liter flow liquid chromatography system comprising at least a first and a second chromatographic column connected in series, wherein an autosampler is provided and programmed to inject samples and eluent solutions of increasing eluent concentration for gradually eluting analytes from the first column into the second column (without adversely affecting separation in the second column), said solutions segmented from the mobile phase of the liquid chromatography system by air plugs. | 06-11-2009 |
