PCT No. PCT/SE90/00273 Sec. 371 Date Oct. 16, 1991 Sec. 102(e) Date Oct. 16, 1991 PCT Filed Apr. 24, 1990 PCT Pub. No. WO90/12890 PCT Pub. Date Nov. 1, 1990A sample of whole blood is contacted with a reagent which by chemical reaction with glucose in the sample brings about a detectable dye concentration change (10) the size of which is determined as a measure of the glucose content of the sample. The sample is initially introduced undiluted in a microcuvette having at least one cavity for receiving the sample. The cavity is internally pretreated with the reagent in dry form, and the chemical reaction takes place in the cavity. Active components of the reagent comprise at least a hemolyzing agent for exposing glucose contained in the blood cells of the sample for allowing total glucose determination, and agents taking part in the chemical reaction and ensuring that the dye concentration change (10) takes place at least in a wavelength range (14) outside the absorption range (12) of the blood hemoglobin. An absorption measurement is performed in said wavelength range directly on the sample in the cuvette. A pretreated disposable cuvette with such a reagent and a photometer are also described.
Abstract:
A device for sustaining a plasma in a torch is provided. In certain examples, the device comprises a first electrode configured to couple to a power source and constructed and arranged to provide a loop current along a radial plane of the torch. In some examples, the radial plane of the torch is substantially perpendicular to a longitudinal axis of the torch.
Abstract:
The apparatus involves a passage transparent to infrared energy for delivering a flow of the fluid through it, an infrared device for radiating infrared energy through the passage, and a detector for sensing infrared energy radiated through the passage and for generating an infrared responsive signal indicative of the detected infrared energy and a datum signal indicative of a nonradiating energy state of the infrared device. A microprocessor controller includes a light timer for generating at a predetermined interval a timing signal to the infrared device, and the infrared device radiates infrared energy in response to the received timing signal.

Abstract:
PURPOSE: A non-destructive inspection method for a post in a construction field and a recording medium are provided to inspect a depth of the post installed under the sea by striking a surface of an object using a hammer generating electric acoustic wave. CONSTITUTION: A non-destructive inspection apparatus includes a post(10), a hammer(20), a geophone(30), a body(40), and an image displaying section(50). The post(10) includes precast prestressed concrete, pre-tensioned spun high strength concrete, and a steep pipe post. The hammer(20) strikes a head section of the post(10) so that elastic acoustic wave and impedance are generated. The hammer(20) is connected to the body(40). The geophone(30) receive an impact wave and impedance after the hammer(20) strikes the head section of the post(10).
