that would be helpful. Chemical struc- tures of the molecules are not included, however. In addition, the analytical chem- ist will find the lack of methods for analy- sis a limitation. To obtain this information, users might want to investigate Instant EPA's Pesticide Methods, a software pack- age just released by Instant Reference Sources. It provides almost 300 pesticide method summaries and offers the same seamless hyperlinks to the other soft- ware in the series. Overall, this software package/data- base is a convenient compilation of the in- formation on pesticides that has been published by the EPA. For those who need only a limited amount of information, or information on only a few compounds, ob- taining the original publications from the EPA would be less expensive, though also less convenient. Likewise, although most of the information included is available in book form in the Farm Chemicals Hand- book (Meister Publishing: Willoughby, OH), the software's search facility and ref- erence listings make it easy to find infor- mation of interest. The analytical chemist may find the program interesting, even though it doesn't contain methods or spe- cific analytical data. Reviewed by Lawrence R.

Its spreadsheet holds up to 32,765 columns and more than 2 billion rows, and an innovative formula calculator provides more than 150 functions for dynamic trans- formation and manipulation of data. Com- prehensive descriptive, comparative, and multivariate statistics methods are avail- able, as well as browsers that speed the analysis process. Users can take advan- tage of 40 templates for frequently used analyses and graphs or create templates for tasks ranging from basic formatting to complex analyses. No command lan- guage is needed because the templates are graphically created. StatView 4.1 runs un- der System 7 or later on any Macintosh (LC or better recommended). It requires 2 MB RAM for 680*0 Macs or 4.5 MB RAM for Power Macs and a hard disk drive. Un-Scan-It Silk Scientific P.O. Box 533 Orem, UT 84059 801-377-6978; 801-378-5474 (fax) Version 3.0; $350 Un-Scan-It 3.0 for Windows turns a PC and any scanner into an automatic (x,y) digi- tizing tablet. It allows users to automati- cally digitize scanned images such as graphs, strip chart output, and old graphs into the computer in (x,y) ASCII format at full scanner resolution. The program can also integrate peak areas, smooth data, take derivatives, enhance data resolution, edit and append data, rescale graphs, and store data in ASCII, JCAMP, or HPGL format for use in other software packages. Un-Scan-It requires an IBM PC 386/486/PS2 or com- patible with at least 1 MB RAM, 1 MB free hard disk space, Windows 3.1 or higher, and any scanner. Chemical Inventory System Window Chem Software 420-F Executive Court North Fairfield, CA 94585 707-864-0845; 707-864-2815 (fax) Version 2.0; $249 Chemical Inventory System, designed spe- cifically for tracking chemicals and other necessary supplies in the laboratory, main- tains information about chemical names, CAS registry numbers, and chemical for- mulas, as well as vendor and catalog num- bers, storage locations, and quantities of two defined container sizes (e.g., bottles and cases). Chemicals and other sup- plies can be sorted by name, CAS registry number, description, vendor, location, or chemical formula. Simple listings or de- tailed reports for any given chemical, supply, or group of items can be gener- ated, including all relevant vendor informa- tion and on-hand quantities. The program runs on PC compatibles and requires a minimum of a 386 CPU, 4 MB RAM, 6 MB hard disk space, and Windows 3.1 or higher. A multiuser version that offers full network support is also available. Kinetics for Windows ARSoftware 8201 Corporate Dr., Suite 1110 Landover, MD 20785 301-459-3773; 301-459-3776 (fax) Version 1.0; $595, commercial; $495, aca- demic Kinetics for Windows is designed to model complex chemical reactions and reaction mechanisms. Its Windows interface allows users to input complex chemical systems by typing the reaction equations and asso- ciated rate constants. The program auto- matically formulates the differential equa- tions that are necessary to describe the kinetics of the chemical system under study. The rate equations are then numeri- cally integrated using a modified GEAR algorithm. Chemical systems containing up to 100 reversible reactions can be evalu- ated, mechanisms with individual reac- tions as high asfifthorder can be exam- ined, computations on systems containing up to 50 chemical species are possible, and a plotting routine is included for view- ing the results of the program. Mini- mum system requirements include an 80386 PC running DOS 5.0 (or later) and Windows 3.1,2 MB RAM, and VGA dis- play. A math coprocessor is recommended but not required.
