为了提高灵敏度,改进了Korkisch和Steffan测定尿铀的分离程序,以便用10毫升尿测定0.1~100微克铀/升水平的铀。为了进一步提高灵敏度,同时对2600型Jarrell Ash荧光计作了改进;用读数为毫伏的电压表作为荧光强度的读数;使用稳定性为0.005%的电源;使用了10、100和1000毫微克
In order to increase the sensitivity, the Korkisch and Steffan procedures for the determination of uranium uranium have been improved in order to determine levels of uranium from 0.1 to 100 micrograms uranium per liter with 10 milliliters of urine. To further increase sensitivity, the Model 2600 Jarrell Ash fluorometer was also improved; a voltmeter reading of millivolts was used as a reading for fluorescence intensity; a power supply of 0.005% stability was used; and 10, 100 and 1000 nanograms
