    摘要: A multidimensional sample separation apparatus includes a first separation dimension for separating a fluidic sample, a second separation dimension for further separating the fluidic sample, a switching mechanism, and a control unit. The first separation dimension includes a first fluid drive unit and a first sample separation unit. The second separation dimension includes a second fluid drive unit for driving the separated fluidic sample, and second and third sample separation units each configured for further separating the separated fluidic sample. The switching mechanism is configured for selectively switching an outlet of the first separation dimension in fluid communication with a selected one of the second sample separation unit and/or the third sample separation unit. The control unit is configured for controlling a pressure at inlets of the second sample separation unit and the third sample separation unit to be substantially the same at least at the time of the switching.

    摘要: A flow controller includes a channel assembly, a pressure sensor, and a pressure control valve. The channel assembly includes a laminated substrate comprised of a plurality of substrates laminated, the laminated substrate having a surface on which a gas inlet and a gas outlet are formed, and having, inside the laminated substrate, a plurality of resistance channels not communicating with one another inside the laminated substrate as internal channels. In the flow controller, the gas inlet and the gas outlet communicate to each other to form a flow rate control channel. The pressure sensor and the pressure control valve are provided on the flow rate control channel. At least one of the resistance channels which is selected to have a desired channel resistance of the flow rate control channel is connected to the flow rate control channel as part of the flow rate control channel.

    摘要: The present disclosure provides adaptive methods for gas chromatography analysis of a gas sample comprising one or more target analytes (such as a micro-gas chromatography) and adaptive gas chromatography devices for carrying out such analytical methods. Broadly, the system can regulate flow into a downstream chromatographic column by detecting one or more upstream conditions. For example, one adaptive chromatography device comprises a first column, a modulator component, and a second column. A first detector or sensor detects the presence of target analytes upstream from the second column, while a second detector detects the presence of target analytes eluted from the second column. The modulator component assembly is responsive to an output generated by the first detector and adaptively regulates fluid flow into the second column. Such adaptive chromatography (micro-GC) systems have higher separation speed, better analyte identification capability, and far greater energy savings.
