Disclosed herein is a suppressor using one ion-exchange tube which has an inner diameter close to that of a tube connected to a separation column and which is constituted by an ion-exchange membrane. The ion-exchange tube is folded or wound more than once in a plane into a sheet form to provide an ion-exchange tube sheet through which an eluate from a separation column flows. The ion-exchange tube sheet is accommodated in a container. The container provides a regenerant flow channel so that a regenerant is allowed to flow on both sides of the ion-exchange tube sheet.

A sensor has an emitting device for emitting radiation pulses repeatedly and a receiving device for receiving these pulses. The receiving device includes a converter such as a photoelectric converter to convert the received radiation pulses into electrical pulses. On the basis of a known waveform characteristic or characteristics of true electrical pulse it is judged if a pulse which appears on the output line of the converter is a true electrical pulse caused by receiving the radiation pulse emitted from the emitting device or a false electrical pulse caused by noise. The result of this judgment is outputted from an output device. The emitting device may serve to emit the pulses according to a specified bit pattern and the receiving device may serve to compare the pattern of received pulses with a standard bit pattern and to thereby distinguish between true and false electrical pulses.

Sensor using radiation pulses

A light detecting IC has a single light receiving element, a first signal processing circuit for processing signals outputted from this light receiving element, a pair of input terminals for receiving signals from outside, a second signal processing circuit for processing signals received from outside through the input terminals, and a switch circuit for selecting one from these two signal processing circuits and outputting results of processing by the selected signal processing circuit. A divided photodiode with two light receiving elements may be connected to the input terminals. Alternatively, another light receiving element which has a larger light receiving surface than the single light receiving element installed on the IC may be connected to one of the pair of input terminals.

Light detector and light detecting IC therefor

A photoelectric sensor transmits pulsed light repetitively, receives light which may include noise and generates a corresponding electrical reception signal. The level of reception signal is compared with a specified threshold value at a timing which is slightly delayed from the timing of light transmission. A sensor output is generated on the basis of the result of this comparison. If periodically changing noise is present and the reception signal has an AC waveform, the level of the reception signal is compared with another threshold value proximal to an AC zero level. The timing of next light transmission is controlled on the basis of the result of the second comparison.

A device for electrophoresis includes a component formed with a pair of planar members such as glass substrates joined together one on top of the other such that a capillary is formed by a groove on the surface of at least one of these planar members. A metallic film is disposed on the inner wall of at least a portion of the capillary, and a transparent prism is provided over this metallic film. Electrodes are inserted both on the same side of the metallic film into the capillary for providing a voltage difference between them for causing migration of a liquid in the capillary for electrophoresis without subjecting the metallic film to the applied voltage. A light source is disposed to cause light to be made incident through the prism onto the metallic film at angles of incidence greater than the critical angle for total reflection and including the resonance angle for excitation of surface plasmons on the metallic film. A detector detects reflected light and a data processor receives detection signals from the detector and obtains a resonance curve for optical excitation of surface plasmons on the metallic film. Data on separation times of known components in electrophoresis are stored. As changes in the resonance curve are detected, components of a sample migrating through the capillary are analyzed.

Device for electrophoresis and component therefor

In order to irradiate a constant range of a separation passage of a microchip, light from a light source linearly extending along the separation passage is transmitted through a cylindrical lens and a bandpass filter and introduced into the separation passage. The light transmitted through the separation passage of the microchip is introduced into a photocell array through a cylindrical lens and detected. Measurement is repetitively performed and accumulated to determine migration patterns.

Microchip electrophoretic method and apparatus

At a room temperature, cleaned glass substrates 8a, 8b are suitably positioned and placed one upon another. A hydrofluoric acid solution or alkaline solution 10 is dropped into the bonding interface between the glass substrates 8a, 8b. The hydrofluoric acid solution or alkaline solution thus dropped spreads along the bonding interface. At a room temperature, a load is then applied to the upper glass substrate 8a and allowed to stand for a suitable period of time, thus bonding the glass substrates to each other.

Method of bonding substrates, detector cell produced according to this

A detector cell in which a pair of glass substrates are used, in which a groove is formed in the surface of at least one of the glass substrates, which has a sample passage formed by the bonding method above-mentioned, a sample inlet port and a sample outlet port, and in which at least a portion of the passage is used as a measuring chamber. There is also formed an optical measuring apparatus having the detector cell above-mentioned and arranged to measure light transmitted through a sample flowing in the passage. According to the arrangement above, it is possible to readily mutually bond, at room temperature, substrates made of a material of glass, quartz or the like of which at least bonding surfaces contain silicon dioxide as the primary component. Further, the optical measuring apparatus having a detector cell produced using this bonding method can achieve a highly precise analysis.

A liquid sample cell used in an optical measurement apparatus in which a liquid sample flows through a flow path of the sample cell while a measurement light travels through the liquid sample in the flow path. The liquid sample cell is composed of: a first glass plate and a second glass plate fixed to each other; a groove for constituting the flow path formed in the first glass plate by a photolithographic method; reflection layers formed on the internal surface of the groove and on the internal surface of the other glass plate; and an entrance window and an exit window formed in the reflection layers to let the measurement light into the flow path and to let the measurement light out from the flow path. The measurement light is reflected by the reflection layers many times in the flow path. Since the measurement light travels a long distance in the liquid sample, the sensitivity of the optical measurement is improved, while the capacity of the flow path is minimized preventing diffusion or mixture of components separated by a chromatographic column, for example.

Liquid sample cell for an optical measurement apparatus

In a multipole linear accelerator such as of a quadrupole type, fine positional adjustment of the tip portions of the electrodes constituting the multipole structure can be made with electric contact kept substantially unaffected between the electrodes and the cavity drum in which the electrodes are mounted. Each of the electrodes are provided with a series of contact plates on both sides of the root portion of the electrode over the whole length thereof. Each of the contact plates, which are held to the root portion of the electrode by means of an adjusting screw bolt, slantwise bridges the root portion of the electrode and the inner surface of the cavity drum with elastic contact pieces interposed. Tightening or loosing the adjusting screw bolts on both sides of the electrode displaces the electrode with electric contact kept unchanged between the electrode and the cavity drum by the elastic effect of the above contact pieces made to interpose between the contact plates and both the electrodes and the cavity drum.
