Abstract: A capillary electrophoresis apparatus is disclosed that does not discharge and achieves both compactness and performance even with a part configuration having insufficient spatial distance or creeping distance. This capillary electrophoresis apparatus is provided with a resistance heater for heating capillaries, an electrode holder that holds capillary electrodes and is connected to a high-voltage unit, and a conductive member that at least partially comprises metal and has been grounded to a low potential. The electrode holder and conductive member are in contact with heat-dissipating rubber disposed there between that composes a structure comprising an insulation member. As a result of this configuration, discharge risk is reduced through the reduction of the potential of parts near the high-voltage unit and the slow reduction of the high potential of the high-voltage unit.

Abstract: With a microspectroscopy device provided with an objective lens with a high numerical aperture, a defocus arises from thermal drift, etc., necessitating auto-focusing. Conventional auto-focus based on through-focus image acquisition takes time, and thus, it cannot be applied to continuous measurement over a long time wherein high-speed sampling is carried out. The present invention addresses this problem by having a defocus-sensing beam that has either defocus or astigmatism fall incident on the objective lens. Since how the image of the spot of the beam for defocus sensing blurs differs depending on the orientation of the defocus, real-time detection of the amount and orientation of defocus becomes possible, and high-speed realtime auto-focus becomes possible.
Abstract translation: 利用具有高数值孔径的物镜的显微光谱装置，由于热漂移等引起散焦，需要自动聚焦。 基于通过聚焦图像获取的常规自动对焦需要时间，因此不能将其应用于长时间进行高速采样的连续测量。 本发明通过具有散焦或像散落在物镜上的散焦感测光束来解决这个问题。 由于用于散焦感测模糊的光束的斑点的图像根据散焦的取向而不同，所以可以实现对散焦的量和取向的实时检测，并且可以实现高速实时自动对焦。

Abstract: A mass spectrometry is equipped with a liquid specimen supply part which supplies a liquid specimen sandwiched between bubbles, an ion source part ionizes the specimen, and a mass spectrometry part which detects ions separated in accordance with mass. In particular the ion source part is configured so as to include a liquid supply tube for transporting a specimen from the liquid specimen supply part, a degassing/liquid retention part in which bubbles are removed, a spraying part which ionizes the specimen, and a high-voltage power supply part which applies a high voltage to the spraying part. The device is further characterized in that after removing the bubbles, a Taylor cone is formed from the resultant pre-solution, and the specimen is ionized thereafter. Thus, the ionization of an intended specimen is stabilized, and the measurement reproducibility is improved.
