Abstract:
PROBLEM TO BE SOLVED: To reduce the amount of handling by the user and to improve the consistency of cleaning conditions. SOLUTION: An apparatus for bringing an array base material into contact with a fluid and a method for cleaning the array base material are disclosed. The apparatus includes a housing for demarcating a cleaning chamber, a fluid injection port communicating with the cleaning chamber to inject a fluid, a drain communicating with the cleaning chamber for draining the fluid, a gas injecting port fitted so as to turn the flow of gas to the surface of the array base material and a program controller operable in connection with the cleaning chamber. The program controller is operable so as to execute a cleaning protocol, including the automatic filling of the cleaning chamber with the fluid. In the method for cleaning the array base material, the array base material is arranged in the cleaning chamber, a first discharge and filling step is triggered, a second discharge and filling step is performed automatically, and a low-speed discharge step is performed automatically.

Abstract:
PROBLEM TO BE SOLVED: To expand a dynamic range without extending measurement or averaging time by selecting output from a discriminator/counter or an electric charge integrator or output from the linear combination of both of them based on the intensity of an output signal for recording or storing. SOLUTION: Incidence light 10 such as fluorescent light is detected by a photomultiplier(PMT) 12, and a detection signal is inputted to a discriminator/ counter 14 and an electric charge integrator 16. Then, the discriminator/counter 14 counts the number of photons regarding a signal that is less than a first selection level, covers a low-level signal within a specific range, and at the same time eliminates excessive noise. On the other hand, the integrator 16 integrates a signal within a strong range up to the saturation/breakdown limit exceeding the second selection level. A control circuit 18 reads the output of the discriminator/counter 14 and that of the integrator 16, stores both the results at a storage device 20, or selects either one of them based on the signal strength for storage.

PROBLEM TO BE SOLVED: To provide an automating process for cleaning an array base material. SOLUTION: In the array base material cleaning method, the array base material is brought into contact with a first cleaning solution and an automatic cleaning process is triggered. In the automatic cleaning process, (a) the array base material is separated from the first cleaning solution, (b) the array base material is brought into contact with a second cleaning solution, (c) the array base material is allowed to stand at a constant temperature in the second cleaning solution under a controlled condition, (d) the array base material is separated from a third cleaning solution, (e) the array base material is brought into contact with the third cleaning solution and (f) the array base material is separated from the third cleaning solution.

Abstract:
PROBLEM TO BE SOLVED: To provide a mass spectrometry using an energy variable type photoionization device (12) for ionizing and/or cleaving molecules. SOLUTION: This photoionization device cleaves molecular in a controlled mode by cutting off specific molecular binding, or selects an ionization photon wavelength from a range of a wavelength in which ionization photon energy can be adjusted in order to ionize a molecular without accompanying excessive fragmentation. The wavelength selection can be performed by selecting plasma formation gas (34) to be combined with the windowless emission of an ionization photon (38) from a plasma chamber. Also a mass spectrometry using the selected ionization photon wavelength is disclosed. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an improved fluid technology which is capable of using gradient liquid chromatography and reducing the amount of waste liquid, free of complications, has reproducibility, and shortens the delay time. SOLUTION: A fluidic device is provided with a plurality of fluid-transporting features, extending from a common inlet to a common outlet, and a means for effecting a fluid flow through the fluid-transporting features. Each feature has a differing fluid dwell time. The means for effecting a fluid flow cooperates with the fluid-transporting features, merges fluids from the fluid-transporting features, and produces an output stream from the common outlet. The output stream exhibits at least one desired characteristic generated as the result of the differing dwell times. It is thereby possible to generate a stream of a micro-volume flow rate and to obtain a smooth gradient in gradient liquid chromatography also. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
A large dynamic range light detection system includes an asymmetric beam splitter for directing a larger fraction of incident light to one photomultiplier and a smaller fraction of the incident light to another photomultiplier. Preferably the light is split in to 90% and 10 % fractions and the photomultiplier receiving the larger fraction is operated in photon counting mode and the photomultiplier receiving the smaller fraction is operated in integrating mode. The beam splitter may be uncoated glass and fast modulators attenuate incident light on the photomultipliers.
Abstract:
An aerosol is produced by flowing a liquid sample through a gas-assisted nebulizer. The liquid exits from an outlet 248 into a coaxial flow of gas 244. The outlet includes a section that tapers 272 to a sharp edge outlet 212 that inhibits or prevents accumulation of precipitates or salts from the liquid, thereby reducing or eliminating clogging, which is particularly useful for a samples containing high concentrations of dissolved particles, i.e. less cleaning is required. The aerosol may be introduced into a plasma such that molecules are broken into atoms. The atomization may be followed by an analysis such as by optical emission spectrometry or mass spectrometry.
