An assay method enhances reliability of assay of a target material by removing interfering influence of non-target materials through controlling the concentration of the target material in a sample. A reagent kit, a microfluidic device, and a test apparatus are disclosed. The method includes capturing a target material using a capturing agent which selectively binds the target material and determining measured values of reaction products of an enzyme which is activated by the target material, wherein enzyme reactions are conducted in the presence and absence of the capturing agent.

A method and apparatus for measuring endogenous CO concentration in alveolar air, comprising: 1. proposing a method for injecting samples in small amounts, multiple times, intermittently, and establishing a CO concentration relationship between sample gas and gas in a gas chamber after completion of sample injection; 2. establishing a "concentration difference/electrical level difference" difference value fitting method, to obtain a fitted standard curve for a difference value between the sample gas and base gas; 3. establishing an apparatus capable of measuring both CO and CO 2 , for measuring a CO concentration difference and a CO 2 concentration difference between sample gas and base gas; 4. proposing a method for compensating a measurement value for endogenous CO in alveolar air. The problem that the amount of sample gas in a breath test is small, and cannot completely replace the gas originally inside the gas chamber, is solved through the adoption of the method for injecting samples in small amounts, multiple times, intermittently. The difference value fitting method effectively eliminates the effects of electrical level zero drift and residual CO of unknown concentration in cleaning gas. The compensating method can eliminate offsets caused by the temperature and pressure at the time of measurement being different from the temperature and pressure at the time of calibration or by air from the surroundings being mixed into sample gas.

Various approached to can be used to interrogate a surface such as a surface of a layered semiconductor structure on a semiconductor wafer. Certain approached employ Second Harmonic Generation and in some cases may utilize pump and probe radiation. Other approaches involve determining current flow from a sample illuminated with radiation. Decay constants can be measured to provide information regarding the sample. Additionally, electric and/or magnetic field biases can be applied to the sample to provide additional information.

Ein Verfahren zum Erkennen des Verschmutzungsgrads von PV-Modulen (2) eines Strangs (3) umfasst die folgenden Schritte: - Bestimmen der Abweichungen (33) der Strang-Leistungswerte (31) von einem berechneten Referenzwert (30) über das letzte Jahr; - Berechnen einer historischen Trendlinie (34) aus den Abweichungen (33); - Ermitteln einer maximalen Differenz (35) zwischen der Trendlinie (34) und den Abweichungen (33); - Berechnen von finalen Abweichungen (36) der Leistungswerte durch Subtraktion der maximalen Differenz (35) von der Trendlinie (34); und - Ermitteln des Verschmutzungsgrads (39) durch Subtraktion der finalen Abweichungen von den Abweichungen.
摘要:
An apparatus to detect and measure suspended particles in a molten metal where the suspended particles have an associated noise frequency range has in addition to the electrically non-conductive barrier for immersion in the molten-metal, a device to move the molten metal through an orifice in the barrier and electrodes, a time varying excitation source that generates an AC current at a predetermined range of excitation frequency that is out of the predominant noise frequency range to generate an AC signal that is representative of the measure of the suspended particles. A detector detects and quantifies from the measurement AC signal the suspended particles. The detector can be a synchronous detector.

Nuclear quadrupole resonance measurement using two or more wire loop(s) (306, 410) within a space to define a portal, and driving the wire loop(s) with a baseband digital transmitter generating a chirped or stepped signal, to create a corresponding varying electromagnetic field within the portal (300). Coherent emissions reflected thereby are detected through a directional coupler (504) feeding the transceiver. The detected coherent emissions are processed with a matched filter to determine presence of a target object within the portal.
