摘要:
A plasma X-ray source comprises inner and outer cylindrical electrodes disposed coaxially and with a certain distance with respect to each other, an electrical insulator disposed between end portions of the inner and outer cylindrical electrodes, and a discharge vessel disposed to envelop the inner and outer cylindrical electrodes. A pulse voltage is applied between the inner and outer cylindrical electrodes to produce plasma in the discharge vessel. An electrically conductive spherical shield is disposed to envelop a space where the plasma is pinched, and the spherical shield is maintained at a potential equal to that applied to the outer cylindrical electrode.

An apparatus for treating solid surface using a thermally excited molecular beam according to the present invention is capable of completely preventing flying of contaminant caused by a heating source to a sample. To achieve this, in the present invention, the heating source for exciting the molecules is hermetically separated from the sample. Alternatively, a container where the heating source is housed and a container where the sample is accommodated are separated such that a conductance between the two containers is sufficiently small. In this way, chemical reactions between the molecular beam of the reactive gas which is highly reactive and the heating source heated to high temperatures can be eliminated, and flying of the contaminant to the sample can thus be greatly reduced. As a result, flying of the contaminating substances caused by the heating source to the sample can be prevented, and reduction in the surface treating rate of the sample, caused by the contaminant, can be prevented.

In an analysis system for detecting amounts of components contained in samples, many samples can be measured simultaneously in the whole of the system by use of compact inexpensive photometers. An LED with low heat generation and a long life span is used as a light source. Compactness is achieved by bended optical axis instead of a straight one. Components for bending an optical axis and components for condensing light to ensure an amount of light are in common use to reduce the number of components. Compactness, reduction of the number of components, and integration achieve easy optical axis alignment and precise measurement.

The present invention provides a method for producing a high-quality capillary tube used in an electrophoresis apparatus in a safe and inexpensive manner. A polymer coating on a capillary tube is converted into gas and removed through an oxidative reaction with oxygen radicals resulting from ozone decomposition, thereby providing tapered polymer coating. The material of the polymer may be polyimide.
