About This Issue: HPLC John W. Moore, Edlfor Eastern Michigan University Ypsilanti, MI 48197 The single program in this issue, "HPLC", is one of only a few instrument simulator programs currently e ~ t a n t . ~AsJ a flight simulator provides an introduction to the situations a pilot will encounter, so an instrument simulator provides a very realistic introduction to the operation of a scientific instrument. Studentsr~neasilyandquickly prartire making the decisions that will need to be made amhen they operate a real instrument, and a much broader range of chromatographic separations becomes available to them than would he possible with a real instrument. The pedagogic advantages of using the simulator both before and after students operate the real instrument are enormous. Even if onlv afew cimputers are a\.ailable, the much greater speed withwhich simulated separations can be c ~ r r i e dout ailours much more learning to occur. This program is a much expanded version of one that has already appeared in the Project SERAPHIM Catalogue.5 In particular, the computer data system is much improved-so much so that it compares favorably with most of the commercial instruments available. Also, the detector has been
enhanced to include a diode-arrav mode, which permits the complete spectrum of any of thechromatographic peaks to he recorded and displayed. Hardware Requirements "HPLC" runs under MS-DOS or IBM PC DOS and is suppliedon a5.25-in. disk. I t can be used on a computer with either a single 5.25-in. or a single 3.5-in. floppy disk drive, or on a computer with a hard (fixed) disk. At least 512K of RAM is required as is a graphics adapter (color graphics adapter-CGA, enhanced graphics adapter-EGA, or video graphics array-VGA). In some cases one may wish to have a graphics printer to print copies of the chromatograms, hut the program will run without a printer. HPLC requires a mouse, since most choices are made by moving a mouse cursor to one or another screen graphic that represents one or another module of the instrument. The mouse must have mouse-driver software that is compatible with the Microsoft Mouse. Such software is supplied with most mice; it is not included with the HPLC disk. Schatz, P. F.
