Provided are an AP node to which a plurality of sensors is connected; and a DB node connected to the AP node. The AP node includes: a receiving unit configured to receive measurement data including values of a plurality of measurement items output from each of the sensors; a queue that stores a most recent value in units of measurement items of each of the sensors; a determination unit configured to refer to the queue and then determine whether the value of each of the measurement items has changed, every time the measurement data is output from each of the sensors; a transmission unit configured to, in a case where there is a measurement item having a value change, generate storage data including the value of the measurement item for each of the measurement items and transmit the generated data to the DB node; and an overwriting unit configured to overwrite the most recent value in the queue with a newest value of the measurement item. The DB node includes: a plurality of tables that stores a value included in the measurement data for each of the measurement items of each of the sensors; and a storing unit configured to store the storage data transmitted from the AP node in a corresponding table.

Data management system

A thermal analysis step, a molecule ionization step and a molecular structure analysis step are executed in parallel to a temperature increasing step. In the molecule ionization step, component molecules contained in gas evolved from a sample S due to temperature increase are ionized, and in the molecular structure analysis step, any selected ion out of molecular ions obtained in the molecule ionization step is dissociated to generate fragment ions corresponding to the structural factors of the molecule, and the structure of the molecule is analyzed on the basis of the fragment ions.

Method for analysis of sample and apparatus therefor

An ionizing deviceincludes an ionization chamberhaving an ionization spacefor ionizing sample molecules A, filamentsandto have an electron impact on the sample molecules A in the ionization space, to ionize the sample molecules A, and an electric discharge tubeto irradiate the sample molecules A in the ionization spacewith ultraviolet light, to ionize the sample molecules A.

Ionizing device

A plurality of molecule components included in a gas are to be ionized at the same time by PI method. For instance, a plurality of molecule components included in a gas generated at a certain instance are accurately analyzed in real time based on PI method. A gas analyzer is provided with a gas transfer apparatus for transferring a gas generated from a sample in a sample chamber to an analyzing chamber; an ionizer for ionizing the gas; a quadruple filter for separating ions by mass/charge ratio; and an ion detector for detecting the separated ions. The ionizer is provided with an ionizing region arranged in the vicinity of a gas exhaust of the gas transfer apparatus, and a lamp for applying light on the ionizing region. Since the lamp outputs light which has light directivity lower than that of a laser beam and travels by spreading, the gas entered the ionizing region in the ionizer receives light in a wide range, and the gas components inside are ionized at the same time.

Gas analyzer

Ions obtained through EI process from a first gas are subjected to mass analysis to obtain ion intensities which are stored in a first file, and ions obtained through soft ionization process from a second gas having same concentration of components as that of the first gas are subjected to mass analysis to obtain ion intensities which stored in a second file, and molecular weights are determined based on parent ions from soft ionization measurement data. A mass spectrum corresponding to the determined molecular weight is read out based on an NIST database, and the ion intensity data stored in the first file and the read out NIST data are compared with each other, and component molecules of the first gas are determined based on the comparison results. Qualitative analysis of mixed gas can be conducted in real time with high accuracy by making effective use of the measurement data of both mass analysis based on EI process and mass analysis based on soft ionization process.

Gas analyzing method and gas analyzing apparatus

A stopper change device () includes an airtight chamber body () detachably mountable on a head of a bottle, a gas supply port () for supplying N gas to the chamber body, an air vent valve () for discharging air from the chamber body, a first supporting structure () movable upward and downward for supporting a corkscrew, and a second supporting structure () movable upward and downward for containing a substitute stopper. The first and second supporting structures are mutually position changeable, and one of them is selectively placed above an opening of the bottle. When the first supporting structure () is placed above the opening, a bottle stopper can be pulled in N gas atmosphere. On the other hand, when the second supporting structure () is placed above the opening, the substitute stopper is mountable on the head of the bottle in N gas atmosphere. By changing the bottle stopper with the substitute stopper using this device, entering of air in the bottle as a cause of deterioration in a quality can be prevented.

Device for exchanging a bottle closure

A fluid extracting device is structured to be capable of extracting only a predetermined amount of a fluid such as wine or the like while a deterioration preventive gas is being supplied to a bottle B and the fluid extracting device (), which are coupled to each other in an airtight state. Consequently, the partial extraction in a plurality of operations is made possible without causing quality deterioration of the fluid such as wine or the like even after the bottle is once opened. Further, such a structure is provided that the fluid extracting devices () having a large number of bottles of wine or the like attached thereto are mounted on a display table at a wine bar or the like.
