摘要： The adaptive temperature controller includes an ambient temperature sensor, a device for measuring resistance, an electrically-conductive material, a power supply, and a device for controlling power. In operation, the controller determines the resistance of material at or near ambient temperature. Based on such determination so long as voltage and power are known, the resistance of the material, and therefore its instant temperature is known. Additionally, the adaptive temperature controller determines the responsiveness of the electrically-conductive material to determine the predicted increase in temperature and rate of increase in temperature relative to increases in voltage, current or power. As a result the voltage or power may be instantly varied to produce near infinite control over material temperature.

摘要： The adaptive temperature controller includes a device for measuring resistance, an electrically-conductive material, a power supply, and a device for controlling power. In operation, the controller determines the resistance of material at one or more temperatures and therefore determines the resistance of the material through a range of operating temperature. Based on such determination so long as voltage and power are known, the resistance of the material, and therefore its temperature, are known. As a result the voltage or power may be instantly varied to produce near infinite control over material temperature.

摘要： A pulsed discharge detector includes a device and method for modular measurement of ionization signals from a sample. The pulsed discharge detector includes a discharge source in a chamber, a collector spaced from the discharge source, a monitor connected to a discharge electrode, an electrometer connected to the collector, a calibrator and a sample and hold processor. The discharge electrodes include a source electrode centrally located in relation to the discharge chamber wall. The collector is centrally located in relation to the chamber wall. Discharge signals are monitored for time and intensity. Collected signals are adjusted based on the discharge intensity. Collected signals are collected during a time window based on the discharge occurrence time. Detector output is predicated on collected signals coordinated with pulsed discharges. The calibrator of the present invention adjusts the collected signals to reduce discharge noise. The sample and hold processor accumulates selected adjusted signal values to quantify sample concentrations.

摘要： A detection system measures very small concentrations of compounds of interest within gaseous samples. A spark discharge system induces pulsed spark discharges across a pair of electrodes within an inert gas in a gas flow chamber. Various reactions are induced by spark interaction with the flow of inert gas, and with any sample or dopant commingled with the inert gas, in the region of the pulsed spark discharge. This induces photon ionization which creates an instantaneous current flow within the gas flow chamber. Current flow is held constant for all concentrations of sample introduced into the gas flow by means of a control feedback system. The output of the control feedback system is indicative of sample concentration. The system responds linearly over approximately five orders of magnitude of sample concentration for use with the sample which will be described and low femtogram sensitivity is achieved.
