Four-circle automatic X-ray diffrac-tometer uses a tangentially mounted detector to increase reciprocal space sampling. The KUMA KM-4 has posi­tioning accuracy to 0.00125° for ω and 2Θ and 0.0025° for κ and φ, and con­tains easily removable collimators and slits. Automatic peak-hunting and cell reduction algorithms are included in the PC-controlled system. Advanced Diffraction Systems 412

Standards. Database on CD-ROM contains all standards published by the American National S tandards Insti tute, as well as international standards information that includes U.S., ISO, and IEC standards. Texts are searched by keywords, and an in­dex/cross reference feature allows the user to access related standards information. Updates are available every 60 days.

P r o c e s s c h e m i s t r y . BatchCAD batch reaction simulation software models laboratory processes for opti­mization of production scaleup, haz­ardous operations, and accelerated process design. The software runs on a PC with a 286 or higher processor, a math coprocessor, and 1 MB RAM. Its menu-driven interface allows the user to predict batch reaction compo­sition for up to 26 species and 20 concurrent reactions, with options for degree of polymerization and iso­thermal or adiabatic operation. Reac­tor design with vessel specifications from a user-defined library can be optimized through thermal safety, pressure, and quench calculations, and distillation dynamics and calori-metric processes can be simulated.

HPLC. "Troubleshooting HPLC" is an interactive computer-based train­ing program with animated color graphics. Topics include baseline, peak shape, and retention problems; ghost and negative peaks; plugs and leaks; instrument cleaning, preven­tive maintenance, and repair; and performance tests. Program runs on

a PC with a 286 or higher processor, 1 MB RAM, 2 MB free space on hard disk, Windows 3.0 or higher, and a mouse. Phenomenex 415

Regulatory compliance. Audit-PC Version 1.52 software for hazard analys is s tudies conta ins an en­hanced range of regulatory checklists that can be used as is or customized for safety compliance audits and re­views.
