摘要： The particle separation and collection assembly uses cyclonic forces to separate and remove large particles from an airstream and concentrate small particles for sensor/detector technology. This assembly utilizes multiple mini cyclones operating in parallel to reduce the size and velocity of air through the cyclone inlets while maintaining the same fluid or flow rate as compared to one large cyclone. The multiple cyclone system can be arranged in a radial geometry or in a bipolar or uni-polar longitudinal design. The particle separator and collection assembly uses a blower or vacuum pump to draw outside gas into the cyclone particle separator assembly through radial inlets. Vacuum transfer channels, extending the entire length of the assembly, pull gas into the top of the cyclone chambers and out through the bottom apex of cyclone chamber and through the top vortex finder. Gas entering the cyclone particle separation chambers from the inlet swirls downwardly through cyclone chambers due to the tangentially aligned inlet. The gas travels in a helical pattern downwardly toward the bottom of cyclone chambers. Some of the air carrying particles smaller than the cut reverses direction and leaves the cyclone through the top vortex finder. The rest of the air exits the cyclone at the bottom. The geometry of the cyclone determines particle “cut” size. Due to centrifugal forces, the particles larger than the “cut” size flow outwardly away from the center axis of the chambers and toward the walls of the respective chambers. Liquid is pumped into chamber from a liquid reservoir through the central liquid passage tube. This liquid wets the particles in chamber and washes down the chamber walls flushing the particles into the reservoir. The liquid is continuously recirculated through the conical chambers by the peristaltic pump thereby concentrating the particles within the liquid over time. The liquid then can be pumped to an optionally integrated monitoring system comprised of detectors and/or sensors. The monitoring system then can send out a warning if toxic microorganisms are present.

摘要： An electrochemical sensor for organic molecules such as ethylene includes an electrochemical cell, gas sample inlet means and means for detecting current produced by the oxidation of the organic molecule at the anode of the cell. The sensor is capable of sensing multiple organic molecules in some embodiments. A voltage is applied to the anode of the cell to provide energy to drive the oxidation reaction and produce a corresponding current. The sensor of the invention can be made as a small, hand-held unit that is capable of real-time detection of various organic species.
