摘要： Electrical contact members 20, 22 for supplying transverse electrical current to a tubular furnace member (22) for electrothermal atomization of samples for analysis by atomic absorption spectrophotometry, the tubular furnace member having diametrically opposite, longitudinally-extending contact ribs (84, 86). The contact members (20, 22) form, in operative assembly, a cavity 88 in which tubular furnace member (24) is accommodated and is held between V-shaped channels (44, 76) in contact members (20, 22). Cavity 88 is formed by a recess (36) in one contact member (20) and covered, except for a separating gap, by the other contact member (22). Respective inert protective gas passages (62, 82) terminate at one end in channels 44, 76.

摘要： A needle is movable by a servomotor between a position of rest and an operating position in a stationary housing. The needle includes a tip and a first lateral opening close to the tip and a second lateral opening spaced therefrom. A longitudinal passage of the housing through which the needle is guided includes a pair of seals at the lower end and a seal at the upper end. A carrier gas conduit ends in the longitudinal passage axially inwards of the seals. A port communicating with atmosphere ends axially inwards of the upper seal. The arrangement permits a sample extraction from sample vessels closed by a membrane without the sample vessels having to be lifted and pressed against the needle.

摘要： Stray light produced in a monochromator by the diffuse reflection of the incoming light beam specularly reflected from the surface of the diffraction grating is practically eliminated by interposing a black glass "absorbent-reflector" in the path of the specularly reflected beam. The small percentage of radiation that is not absorbed by the absorbing glass is reflected to an opposite blackened wall which diffuse reflects an extremely small percentage of the beam back to the absorbent-reflector where a very negligible part is returned to the grating surface and eventually to the monochromator exit slit.

摘要： Closure for a sample vial utilized to introduce sample into a gas chromatograph in accordance with the head space method. The closure includes a flexible disc for closing the opening through the neck of the vial and overlying the margin of the neck about the vial opening. A cap having a central aperture defining an annular shoulder about the aperture overlies the disc. The cap has an annular depending skirt encompassing the disc for clamping about the neck of the vial to retain the disc and the cap on the vial. A portion of the closure is deformable for venting the vial to atmosphere in response to a pressure within the vial when the closure is applied thereto in excess of a predetermined pressure.

摘要： Gaseous measuring samples like element hydrides are generated from liquid samples by reacting the same with reducing reagents in a reactor. In the reactor a countercurrent of inert gas strips the volatile reduction products from the reactor to convey the products to the measuring cell of an analytical measuring instrument. Various embodiments of the apparatus automatically controlling the supply of liquid sample and reagents to the reactor are disclosed such as mechanically or pneumatically controlled pumps. In each measuring cycle the reactor and respective components are washed to prevent contamination of succeeding samples; also, analytical determination of blank values as well as reference values can be included in each measuring cycle.

摘要： A graphite tube atomizer for flameless atomic absorption spectroscopy includes a graphite tube disposed to permit passage of a measuring beam therethrough. The graphite tube is engaged at opposite ends by annular contact pieces which are coupled to a source of electrical current. The contact pieces are supported in housing portions which serve to surround the graphite tube and provide a chamber into which cooling gasses can be admitted. The cooling gasses also serve to reduce deterioration of the graphite tube. The housing portions are selectively movable either toward or away from each under the power of a drive mechanism. The housings may be urged by the drive mechanism toward each other so the contacts mounted thereon are in selectable pressure engaging contact opposite ends of the graphite tube.

摘要： An a.c. to d.c. converter is disclosed which includes two resetable integrators each for sampling an alternate half-wave of the a.c. voltage to be converted. During each alternate half-wave, when a given integrator is not integrating the input signal, the integrator output is sampled by an analog memory circuit. After the sampling has taken place, the integrator which has been sampled is reset so that it can again operate properly during the succeeding half-wave. The difference of the output for both analog memory circuits is formed so that the d.c. component of the incoming a.c. signal is removed and the remaining residual ripple in the output results only from changes in amplitude of the a.c. signal itself from one-half wave to the next.
