                          激光测铀仪性能指标



                               由于工作曲线法分析铀样品,虽然分析速度较快,但分析结果受样品成份等因素影响,所以要对其校正,否则影响准确度。WGJ-III型微量铀分析仪,适于应用标?#25216;?#20837;法分析微量铀。适用于核工业,?#32321;#?#21355;生防疫等部门使用。  

                          激光测铀仪性能指标如下: 

                          1.测量对象:直接测量液体样品,对于固体样品,转化为水溶液后,不要分离、富集,适当稀释就可快速测量。 
                          2.检出下限:以标?#35745;?#24046;的三倍定义?#20445;?#19981;大于0.03 10-9g/ml. 
                          3.测量精度:(1)在铀浓度为0.1至2 10-9g/ml范围?#20445;?#19981;大于 8% 
                          (2)在铀浓度为2至20 10-9g/ml范围?#20445;?#19981;大于 5% 
                          4.量程范围:20 10-9g/ml。如果改变灵敏度,可扩展到106g/ml量ji。 
                          5.测量线性:相关系数大于0.998。 
                          6.稳定性:调灵敏度,使铀浓度为2 10-9g/ml的样品读数为850左右样品结果:可由单片机计算及打印、并可通过RS232串口将数据传入普通计算机保存
