Method and apparatus of fluorescence x-ray analysis
专利汇可以提供Method and apparatus of fluorescence x-ray analysis专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain an accurate measurement value eliminating the need for correction under any atomospherin condition by controlling the atomospheric pressure and temperature to remain constant in a passing space of primary X-rays and fluorescence X-rays radiated from a sample. CONSTITUTION:Air in an X-rays room 5 is circulated forcibly passing through a circulation passage 28 by operating a pump 31 and also, a part of the air is discharged outside from a ventilating pipe 41 through a throttle valve 42 passing through a sample room 8. The air circulating the passage 28 is dehumidified by a dehumidifier 30 at first and the humidity is controlled to a constant valve. Hereafter, the pressure is controlled by a pressure control valve 32 and moreover the temperature is controlled by a temperature control device 33. On one hand, X-rays are irradiated to a sample 11 from an X-ray generator 22 and the intensity of fluorescent X-rays radiated from said sample 11 is measured by a counter 23. Hereby, the accurate measuring value is obtained even under any atmospheric condition without correcting the factor giving the influence to a dose of the X-rays.，下面是Method and apparatus of fluorescence x-ray analysis专利的具体信息内容。
