摘要： Method and device for quantifying ingredients of a plume. In one embodiment, the method includes sweepingly directing a beam of light through the plume to a surface on which the beam of light is scattered, acquiring the scattered light scattered from the surface, and processing the acquired scattered light to determine an amount of ingredients of the plume. In one embodiment, the height of the back of the vehicle is measured as the top of the plume for calculating the total mass-per-distance of the plume. In another embodiment, by comparing the absorption spectrum of the plume and the background absorption spectrum of which no plume exists, the non-methane hydrocarbons (NMHC) of the plume emitted from a vehicle can be quantified.

摘要： Chemical sensors can detect the presence of chemical species in solution based upon polymer swelling in response to the chemical species. Polymer swelling is indirectly determined by measuring electrical properties of the detector element (9), the state of an electric circuit containing the element or light reflected from a reflector (7) affixed directly (8) or indirectly to the polymer (9) such that increase or decrease in the size of the polymer (9) changes the distance between the reflector (7) and a light source. Measurements of the amount of swelling or shrinkage of the polymer reflect the presence of the chemical species.

摘要： A molecular characterization detector (8) includes a scattering cell (10) containing a sample for molecular characterization, a light source (20) for directing a light beam through the cell (10) so that the light beam is scattered by the sample, optical elements (30, 32, 50, 52) for selecting from the scattered light a measurement beam (40) comprising light that is scattered by the sample from a predetermined portion of the cell (10) in a predetermined range of angles relative to the optical axis (22), and a detector (44) for detecting the measurement beam and providing an output electrical signal representative of the measurement beam. The detector (44) typically selects light scattered from a central portion of the scattering cell at angles in the range of 14° to 16°. A single spherical lens (18) is preferably utilized. As a result, interference from stray scattered light is minimized. A beam dump (24) attenuates the light beam after it passes through the scattering cell (10). Additional detectors (62, 70, 80) detect light scattered at 90° to the light beam. The outputs of the detectors (44, 62, 70, 80) are processed to provide molecular characterization of the sample.
