摘要： An apparatus for chemical treatments has an enclosed vessel provided with lines for conveying samples and selectively openable valves in communication with sources of gases at atmospheric, increased, and reduced pressures. A plurality of such vessels may be combined, instead, in which case the pressure of the atmosphere in each vessel is made higher than that in the following vessel, so that the sample can be transferred to the following vessels. The vessel or vessels may be equipped with means for agitation, fixed-quantity sampling, liquid level detection, washing, filtration, extraction, thermostatic control, aeration, thermal concentration and distillation. An additional vessel equipped with pH-adjusting means and capable of maintaining an atmospheric pressure inside may be installed.

摘要： A system for analyzing the photometric properties of a sample of material, which comprises a means for projecting a light beam from a light source to a flame into which the sample to be analyzed and a reference material are alternately introduced, a detector for detecting the intensities of the sample beam and the reference beam which have been transmitted through the flame, and a means for comparing an electric signal indicative of the intensity of said sample beam obtained from said detector with the other electric signal indicative of the intensity of said reference beam.

摘要： A glow discharge lamp provided with an anode and a cathode which comprises a first cylindrical cup member and a second cylindrical cup member having a smaller outer diameter than that of the first cylindrical cup member and being inserted vaportightly into the first cylindrical cup member with a space therebetween for accommodating a lump of a low-melting-point metal, the hollows of the two cup members are communicated with each other by means of a through hole having a predetermined diameter such that an amount of vapor of the low-melting-point metal may be controlled in the hollow of the second cylindrical cup member, whereby the lump is heated by electron discharge caused between the anode and the cathode and effectively vaporized so that the desirable amount of the vapor flows into the second cylindrical cup member.

摘要： A liquid film type, anion-selective electrode of the present invention is suitable for measuring a chloride ion concentration of blood. A sensitive film contains a plurality of plasticizers having different dielectric constants, an anion-sensitive substance and a polymeric support material for supporting them. An appropriate content of o-nitrophenyloctylether having a high dielectric constant is 5-30% by weight, an appropriate content of n-tetradecyl alcohol having a low dielectric constant 5-40% by weight, and an appropriate content of dimethyldioctadecylammonium chloride as the anion-sensitive substance is 5-30% by weight. An electrode for measuring anions with such a sensitive film has less adverse affect by protein on measurements. The sensitive film further containing n-dodecyl alcohol has a much smaller error of measurement.

摘要： By use of excitation beam having a wavelength which is equal to, or close to, the sizes of particular particulate substances as the object of analysis, the particulate substances such as an immunoreaction product between an antigen and an antibody or between the antigen and a material supporting thereon the antibody are detected selectively. Very small particles having specific sizes such as rheumatuid factors, cancer specific antigens can be detected highly sensitively.
