Introducing the NEW CS-2000! This advanced computercontrolled electroanalytical | system allows you to: • • Product line for isocratic and gradient micro-HPLC includes microflow rate pump, microbore and capillary packed columns, 250-nL and 1.2-μΙ. microflow cell detectors, injectors, integrator, autosamplers, and data acquisition and analysis software. Three readily interchangeable flow rate ranges and four independently controlled solvents are featured in the systems. Target applications include microLC/MS, trace analysis, sample-limited analysis, chiral separations, and solvent saving. Micro-Tech Scientific 422
ber to perform automated tests with optional stirring. Multiple testing programs, including Pensky Mar tens, TAG, COC, 140 °F flash/no flash, and other tests, can be entered and stored, and test d a t a can be stored or transferred to a printer or computer via an interface port. Con ditions and results may be expressed in °C or °F. Petrolab " 419 ICP. ICP optical emission spectrom eter substitutes a CCD array detec tor for conventional photomultiplier tube detectors. The spectrometer fits on a benchtop and has no moving op tical parts. Baird Analytical 420 Mercury analysis. High-speed cold-vapor mercury analyzer fea tures on-line sample digestion and follows EPA Method 254.3. The sys tem can run 40 samples per hour and has a detection limit of 40 pptr. A DOS-controlled 76-position autosampler and data acquisition soft ware are included. Columbia Analyt ical Instruments 421
use with MDL databases, MACCS, and REACS. SoftShell 423 AAS. PC/Absorb is an i n t e g r a t e d hardware/software package for re porting AAS data from a recorder an alog signal. The program collects data during both flame and transient modes, t r a c k s individual samples and standards, calculates concentra tions of unknowns, and converts data files to ASCII format for postrun processing with the user's plotting, word processing, and s p r e a d s h e e t programs. A demonstration disk is available. Hamilton & Associates 424

P h a r m a c o l o g y . United States Phar macopeia and the National Formulary have been compiled as a computer database t h a t presents standards of strength, quality, purity, packaging, a n d labeling for more t h a n 3200 drugs, medical devices, and diagnos tic products, as well as standards for 300 pharmaceutic inactive ingredi ents. The database includes USP-NF Supplements and is updated annually. United States Pharmacopeial Con vention 425
D r a w i n g p r o g r a m s . Chemlntosh and ChemWindow Version 2.1 chem istry drawing programs have a new file format t h a t supports chemical structure data and graphic informa tion. The programs are designed to provide cross-compatibility between Macintosh and Windows formats as well as with other companies' draw ing programs. Chemlntosh can ex port to Aldus PageMaker and Quark XPress, and ChemWindow creates WordPerfect Graphic files. Both pro grams import and export Molfile for
Distillation. SimDis Expert simu lated distillation software version for PC Windows, designed to analyze crude and lubricant oils as well as o t h e r h y d r o c a r b o n m i x t u r e s , can read chromatograms from Windowsbased GC data acquisition systems. The software p r e s e n t s o n - s c r e e n peak identification for retention time calibration and allows peak identifi cation changes in cases of low con centration or impurities by clicking and dragging with the mouse.
