【摘要】 |
|
The feeding-sample system used by microwave plasma torch atomic emission spectroscopy (MPT-AES) is the pneumatic nebulization system; its efficiency, however, is not good. A newly built injector pump–ultrasonic nebulizer combination feeding-sample system has been designed. Its performance was tested and compared with that of the pneumatic nebulization system. It can be concluded that the newly built feeding-sample system can increase the spectral line intensity by about two to three times and decrease the detection limit by about 2 to 10 times. Moreover, this newly built system can reduce the time taken washing the sample cell from 30 min or so to about 10 min. |
