摘　　要：Further advancement of ICP-AES analytical technique is hindered by complex spec-tral interferences.The correction algorithms recently proposed need too much computation andtime to run in real time on general microcomputers.In this paper,a new kind of spectral interfer-ence fast correcting system(SIFCS)was developed,in which the hardware is a TMS32020 digitalsignal processing board in IBM-PC I/O channel and the software is composed of a correctingprogram based on a new effective algorithm and a master program on IBM-PC.Experimentsshow that the processing speed on SIFCS is 50-100 times faster than that on IBM-PC/AT.Thismakes real-time correction of spectral interferences feasible.Further advancement of ICP-AES analytical technique is hindered by complex spec- tral interferences.The correction algorithms recently proposed need too much computation and time to run in real time on general microcomputers.In this paper,a new kind of spectral interfer- ence fast correcting system(SIFCS)was developed,in which the hardware is a TMS32020 digital signal processing board in IBM-PC I/O channel and the software is composed of a correcting program based on a new effective algorithm and a master program on IBM-PC.Experiments show that the processing speed on SIFCS is 50-100 times faster than that on IBM-PC/AT.This makes real-time correction of spectral interferences feasible.
