| Abstract: | The accuracy, stability and continuity of online monitoring instruments have closely related with the reliability of online monitoring system. Seven different online cadmium monitoring instruments were chosen to comprehensively evaluate their monitoring performances. The results indicated that the linear error, relative deviation, repeatability error, zero drift and span drift of five online monitoring instruments were less than 10%, 10%, 5%, 5% and 10%, respectively. |
