摘要:
A method for assaying an enzyme on a targeted solid body surface, including the steps of contacting an end opening of a thin tube with a targeted solid body surface to form a space between the targeted solid body surface and inner wall surface of the thin tube, supplying a substrate solution into the space to bring the substrate solution in contact with the targeted solid body surface, and determining a pH change of the substrate solution in the space by using a pH electrode; and an apparatus therefor.
摘要:
There is disclosed an apparatus for the determination of a trace amount of an analyte substance or organism. A substrate solution is brought into contact with a small diameter tube which has captured, at least on its inner surface, a trace amount of an analyte substance or organism. The trace amount has the ability to change the pH of the substrate solution. A pH change following a reaction of a substrate in the substrate solution in the small diameter tube is measured; the apparatus has a cuvette having an inlet and an outlet for the substrate solution, a pH electrode accomodated in the cuvette, a pump for supplying the substrate solution in the cuvette, a positioning structure for positioning, in the cuvette, the small diameter tube with the pH sensitive plane of the pH electrode and spacing the surface and the plane at 1 mm or below from each other, and a sealing structure for maintaining a formed by the outer surface of the small diameter tube accommodated in the cuvette and the inner surface of the cuvette at liquid tight condition.
摘要:
A method for measuring trace amounts of analyte substance(s), which utilize a pH electrode is disclosed. This method is by far simpler than conventional optical detecting systems. The apparatus for practicing the method is also disclosed. By the use of pH electrode, the apparatus is compact, inexpensive and easy to operate, and hence usable in small-size and medium-size hospitals or clinical laboratories and by patient's bedside.

Disclosed are a pH or concentration measuring device and a pH or concentration measuring method which enable measurement in the shortest possible time even in an object to be measured having low buffer capacity. Specifically disclosed are a pH or concentration measuring device and measuring method for measuring the pH or concentration of a sample solution that is an object to be measured, the device being provided with first and second sensors that each output a signal corresponding to the pH or concentration of a solution, an inspection tube that is provided with a first room in which the first sensor is disposed and a second room in which the second sensor is disposed, a feeding means that feeds a baseline solution into the inspection tube, and an injecting means which injects the sample solution into the first room of the inspection tube and brings the sample solution into contact with the first sensor, wherein a vibration means which vibrates the interface between the sample solution stored in the first room and the baseline solution is provided.
摘要:
An apparatus for measuring the quantities of chemical substances contained in a solution to be assayed by using a chemical-substance sensitive sensor consists of a potentiometric electrode which responds selectively to chemical substances, and a liquid-junction type reference electrode including a tube, a porous thread member housed in the front end opening of the tube and having a pore capacity of 0.2 cc/g or more and at least the surface of which is hydrophilic, a silver-silver chloride wire is provided and housed in the tube so that at one end of the wire is in contact with the thread member and the wire which extends along the tube. The wire is connected to a connector at the other end opening of the tube, an electrical insulating resin fills said tube, at least at the front end portion thereof, for fixing both the silver-silver chloride wire and the thread member by contact therewith and for stopping said tube. An internal solution is retained by suction in said porous thread member. This apparatus is advantageously used for monitoring the living body and may be thermally sterilized.

摘要:
A network facsimile system has a communication terminal and relaying server. The network facsimile system is configured such that the communication terminal can transmit an image, through the relaying server, to a destination terminal outside the network facsimile system, that the communication terminal transmits an image to the relaying server in accordance with a predetermined communication protocol. The relaying server transmits an image to the destination terminal in accordance with a facsimile communication protocol. The communication terminal includes a notification system that notifies a user of the communication terminal of an operation status information indicating an operation status of the network facsimile system during a relaying server side operation period.
