    Abstract: A micro fluid analyzer (500, 600, 610, 620) having a concentrator (523, 623) and two separators (524, 525, 624, 625, 651, 654). The analyzer may have one or two pumps(521, 522, 640, 621, 622). The analyzer (500) may have a hyper pre-concentrator (526) having a number of channels (527). There are numerous detectors (531, 532, 533, 534, 631, 632, 633, 634) positioned along the flow path of the analyzer. Also, one or more orifices (541, 542, 644, 645, 647, 648, 653, 656) and micro valves (641, 541, 661) may be positioned in the flow path. The concentrator (523, 623) may have an array of heater elements (20, 22, 24, 26) that provide a heat pulse that moves along the fluid path to provide an increasing concentration of heat in a fluid. The analyzer may be configured as a multiple fluid or gas chromatograph.

    Abstract: The method and apparatus of the invention create a dynamic Soret effect for propelling a target chemical constituent along a pathway. A moving temperature profile impressed upon the pathway produces consecutive alternating warmer and cooler zones along the path which transport components of a mixture down the path according to their respective diffusivities. In one embodiment, the invention provides a dynamic thermophoretic concentrator for separating a target chemical constituent from a mixture of components on the basis of diffusion coefficient by using alternate forward and backward motion of a temperature profile along the pathway, thereby accumulating an ultimate concentration of the target constituent greater than its initial concentration in the mixture.

    Abstract: A micro fluid analyzer that may be highly sensitive, fast and very compact. The analyzer may use sufficiently low power per analysis to be easily implemented with an equivalently small battery pack or other portable power source. There may be energy conservation features in the analyzer, such as optimal adsorber film thicknesses in the pre-concentrator, concentrator and chromatographic separators. There may be special timing of the phased heating elements in the concentrators and separators to further reduce energy consumption. Various kinds of detectors and sensors may be incorporated in the analyzer for achieving low probability for false positives and detection versatility. There may be a controller that provides data acquisition and analyses, drive signals for control, management of wireless signal transmission and reception, processing, and other operational uses of the micro analyzer.

    Abstract: A concentrator and sensor assembly are disclosed that use phased heaters to multiply the concentration levels that can be eluted, relative to operation with a single interactive element having a sorbent material to increase the concentration of desired gas constituents at a detector. This is accomplished here by providing two or more interactive concentrator elements that are selectively heated in a time phased sequence so that each of the interactive elements becomes heated and desorbs gas constituents into the sample fluid stream at substantially the same time that an upstream concentration pulse, produced by heating one or more upstream interactive elements, reaches the interactive element. This produces a multiplication effect that significantly increases the concentration of the gas constituents at the detector, thereby increasing the effective sensitivity of the detector.

    Abstract: A gas chromatograph (2) and method of chromatography are provided. Analytes (112), those compounds to be tested, are extracted from a sample by moving the sample into a column (100) which has a stationary phase (109) along column walls (110). Column (100) has two sections (101, 102) which are different in length. Longer section (101) is heated and analytes (112) move to shorter section (102). Longer section (101) is then cooled and the entire column (100) is heated. The device then functions as an analytical column and analytes (112) move out of shorter section (102) through longer section (101) and out of column (100). A detector (111) placed at the end of the column's longer section (101) detects the presence of the compounds as they exit column (100). In an alternate embodiment two separate columns are provided. One column is used as the extraction column and the other is used as the analytical column.
