摘要： A thermal conductivity detector (5) for a gas chromatograph comprises a heatable resistive detector element (8, R2) configured to be physically arranged in a flow of analytes eluting from a chromatography column (4) and electrically arranged together with resistors (R1, R3, R4) in separate arms of a measuring bridge. The detector (5) further comprises an amplifier (U1) configured to detect a differential voltage between two opposite nodes of the measuring bridge and to apply an output voltage (10) to the other opposite nodes of the measuring bridge in order to maintain the detector element (8, R2) at a constant operating temperature.
In order to compensate for uncertainties in the operating temperature due to manufacturing variations of the resistors (R1, R3, R4) and/or to allow for processing both small and large peaks of a chromatogram with highest resolution available, an additional resistor (R5) with a controllable switch (Q1) in parallel is connected in series with the detector element (8, R2) or resistor (R1, R3, R4) arranged in one arm of the measuring bridge. The switch (Q1) is periodically turned on and off with a predetermined duty cycle and/or controlled by information (12) on characteristic times-of-arrival of the analytes at the detector.

摘要： An apparatus and method is provided for detecting terrorist bombs. The apparatus is operative to detect small amounts of low volatility atmospheric vapors which are emitted into the surrounding air from the bomb. The apparatus includes a heated inlet nozzle (42) which delivers the air to a silicone membrane (54). A pair of identical capillaries (56,58) are disposed downstream from the membrane (54), with one capillary being polarized, and the other being non-polarized. The heating of the inlet nozzle is periodically increased rapidly to cause extremely low volatility explosive vapors to evaporate and diffuse through the membrane. Detectors (70,72) disposed downstream from the capillaries (56,58) detect the presence of the vapors impinging thereon. Differences in the signals generated by the two detectors is indicative of the presence of an explosive. A microprocessor (74) is provided to recalibrate the detectors after each heating cycle.

摘要： An improvement in the analytical method for determining the presence or concentration of analyte in a solution comprising detecting a dissolved detectable substance in solution with a detecting means, for example, by passing a solution containing a detectable substance through a detection means for determining the presence of concentration of detectable substance in the solution. The improvement comprises mixing the solution with one or more particulate reagents to form a suspension, the particulate reagents modifying the solution to yield a concentration of total detectable substance which correlates with the concentration of original analyte, and passing the solution through the detecting means. The particles can be used to replace an analyte with a detectable substance or an intermediate which can be reacted in solution to form a detectable substance. Alternatively, the particles can be used to suppress or remove an interfering substance. The apparatus is an improvement in systems for sample detection comprising a continuous flow sample source such as a process liquid source, carrier liquid-injected sample source sample separator column such as an ion exchange column or chromatographic column, or a capillary zone electrophoresis sample separator. It also includes a detector for detecting dissolved sample species, and connecting means including a flow passageway communicating with the sample source and detector means. The improvement comprises a particulate reagent reservoir for reagent particles having a particle size of less then 2 microns, and flow control means communicating with the particulate reagent reservoir and with the connecting means flow passageway for metering particulate reagent flow into the flow passageway. The detector should be capable of detecting dissolved sample species in the presence of a particulate reagent.
