以人体体液中微量元素的含量来评估人体的健康程度和分析疾病的成因已经引起医学界人士的极大兴趣。我们曾经就人体全血中微量元素的X-射线荧光光谱测定做过有益的尝试。在进一步的试验过程中发现:对于日本理学3080E。型X荧光光谱仪(入射角ф=63°),X射线在照射薄试样时,会激发出样品盒内壁某些金属元素的谱线,不同程度地影响了分析结果的精密度和准确性。即使采用中空测量,这种干扰也仍然存在。例如,铜含量在临床病因分析中一向受到人们的重视,但由于样品盒的原因无法定量检出。为了消除这种干扰,我们经过反复试验,选用高纯铅应按样品盒内径加工制成铅杯,使其嵌入样品盒内,采用这种方法进行测量,有效地消除了样品盒因受X射线激发而对分析产生的干扰。用X-射线荧光光谱滤纸片法成功地分析了人体体液(全血、血清、脑脊液)中Cu、Zn、Fe、
To assess the human body’s health level and analyze the cause of the disease by the trace elements in human body fluids has drawn great interest from the medical profession. We have done some useful experiments on the determination of trace elements in human whole blood by X-ray fluorescence spectrometry. In the course of further testing found: For Japanese Neo-Confucianism 3080E. X-ray fluorescence spectrometer (angle of incidence ф = 63 °), X-ray irradiation in the thin sample will stimulate the inner wall of the sample box some of the metal elements of the spectrum, to varying degrees, the accuracy and accuracy of the analysis results. This interference is still present even with hollow measurements. For example, the copper content has always been valued in clinical etiology, but not quantitatively due to the sample box. In order to eliminate this interference, we have repeatedly tested, selection of high-purity lead should be processed according to the sample box diameter made of lead cup, embedded in the sample box, the use of this method to measure, effectively eliminating the sample box due to X-ray Excite and interfere with the analysis. X-ray fluorescence spectroscopy filter paper successfully analyzed the human body fluids (whole blood, serum, cerebrospinal fluid) Cu, Zn, Fe,
