Line selection expert system for control of scanning inductively coupled plasma atomic emission spectrometers

Abstract

An expert system for control of a rapid scanning spectrometer t o perform atomic emission spectrometry ha been developed using the PROLOG language. The expert system can be "taught" the elemental composition c a given sample type. It uses this information (when available) t o generate a line-search strategy whicl minimises the number of lines that need to be measured. The rules used by the system can be observec during system operation to allow a trace of the logic. Reading of the initial database takes no more than 6 s anc then decisions are made in less than 1 s per line.

Green chemistry in analytical atomic spectrometry: a review

“…ESs have been included in FAAS spectrometers for full automation (in particular for error detection and correction). 301 In ICP-OES, ESs are used for prediction and correction of spectral interferences, 302,303 spectral line simulation and selection, 304,305 system diagnosis 306 or as a hybrid expert-database system for sample preparation by microwaveassisted dissolution. 307,308 ES has been also used in ICP-MS for controlling the spectrometer, 309,310 the whole sample pre-treatment process 311 and developing a simple diagnostic procedure to automatically ensure the quality of results.…”

Use of multiple emission lines and principal component regression for quantitative analysis in inductively coupled plasma atomic emission spectrometry with charge coupled device detection

“…An expert system, which is capable of 'learni g' the elemental composition of a sample type, and using this information to generate a line selection strategy, has also been described. 13 All of these procedures for line selection determine a priori the optimum spectral line to be used for quantitative analysis as a consequence of the effect of a given sample matrix. In many situations this information may not be available, as the sample matrix is either unknown or may change from sample to sample.…”

“…Chemistry literature abounds with descriptions of expert systems that reflect the power of knowledge-based systems. Applications include areas such as chemical synthesis (12), process control (13), atomic line selection (14) or line analysis (15), spectral interpretation (16)(17)(18), and chemometrics (19). The trend toward increased laboratory automation is reflected in attempts to manage instrument control and operation (20) and in robotics (21).…”
