摘要： A method of emission spectrochemical analysis is provided which comprises the steps of producing a predetermined number of spark discharges between an electrode and a specimen containing an element in a first and second state. The intensity of emission of light caused by each of the spark discharges is measured and a frequency distribution of the measured intensities of emission is obtained. The distribution is separated into an area of normal distribution and an area outside the area of normal distribution, and an intensity of emission value is selected. The amount of the element in the first state is determined as a function of the selected intensity of emission multiplied by the area of normal distribution and the amount of the element in the second state is determined as a function of the selected intensity of emission multiplied by the area outside the area of normal distribution.

摘要： Densitometer for quantitative determination of a sample spot on a thin-layer chromatography (TLC) plate or the like having besides the spot an area of impurities developed thereon, wherein the surface of the plate is scanned in a zigzag way by a light beam having a minute cross section. In one stroke of the zigzag scanning of the area containing impurities immediately before the spot the measured signal is integrated and stored by a first integrator and in each and every one of the succeeding strokes of the scanning of the spot the measured signal is integrated by a second integrator. The stored integrated value of the first integrator is subtracted from the integrated value of the second integrator in each and every one of the scanning strokes across the spot and the result of the subtraction is integrated for quantitative determination of the spot without errors caused by the impurities contained in the sample.

摘要： A spectrophotometer which uses as a detector a silicon photocell and a phototube sensitive to short wavelengths. The light from the sample cell is divided into a smaller and a larger portion. The smaller portion is projected onto the silicon photocell and the larger portion, to the phototube. The two outputs are combined and amplified for indication. The whole of the light transmitted through the sample cell may also be projected to the phototube while the spectrophotometer operates in the short wavelength region and alternatively to the silicon photocell while the instrument operates in the long wavelength region.

摘要： An electrophoretic measurement system for isotachophoresis includes a potential gradient detector, an impedance converter, a voltage to frequency converter, a signal transmission system composed of, for example, electromagnetic wave transmitter means and its receiver spaced therefrom, frequency to voltage converter means, in series connection. This arrangement facilitates insulation of the sensing electrodes of the detector from the ground and prevents a formation of bubbles and deposits on the electrodes, so that the electrophoresis processes are performed under stable condition and high resolution and high sensitivity are obtained. Besides a higher migration current can be used to shorten analysis time.
