• Software 301 REACT for Windows provides researchers and students with the ability to simulate chemical mechanisms. The software includes a mechanism editor and an efficient differential equation integrator. The calculated results can be displayed in tabular and graphic formats. The software can be used to predict species concentrations in a mechanism as a function of time and to model a reaction mechanism under investigation. It can also be used in teaching chemical kinetics. The software is compatible with all Windows operating systems. Alchemy 302 Atlas 2000 is a chromatography data system designed for multiple users and multiple instruments in fully networked, secure, and regulated environments. Features include Report Manager 2000 for more sophisticated reporting capability, including statistical and summary reports;
with a Windows search engine. The data fields that can be searched include inventory name, other submitted names, Chemical Abstracts Service Registry number, molecular formula, and definitions. The software's string search feature is useful when the CAS number is not known. The user creates a pick list of names by entering up to four fragments of names of chemical groups or elements that would be common in the substance's name. A double click on a name brings up a full screen of data for the substance without destroying the list. Softrak
