Laser Fluorescence Detection in Microcolumn Liquid Chromatography: Application to Derivatized Carboxylic Acids*

eter of similar concept to the software slew-scanning system presented in Ref. 7. A more exciting concept is a mul t ichannel direct-reading type processor which would incorporate several pairs of MACs and thus would allow parallel processing of an interferogram for several elements. Such a "di rec t reader" could be instant ly reconfigured under firmware control, as the "channels" of direct reader are simply de termined by the masks sent to the MACs. Such a system could be based on a modes t number of channels, say ten. Based on this concept a versatile and inexpensive real-t ime correlat ion-based data processor could emerge for inductively coupled plasma/Fourier t ransform spectroscopy. 1.
