Software LIS d e m o n s t r a t i o n . Demonstra tion software package based on the full-function version of Lab VIEW for Windows graphic programming soft ware provides an overview of the sys tem, basic concepts, and hands-on examples. The user can explore or build a virtual instrument program for instrument driving, data aquisition, and data processing. National Instruments 412 Size e x c l u s i o n chromatography. Turbochrom 3 SEC software package features automatic generation of
user-selected SEC reports and plots and has five curve-fitting options for molecular weight calibration, includ ing point-to-point; first-, second-, and third-order; and cubic spline. The software uses either narrow or broad molecular weight standards to generate the calibrations and pro vides a universal calibration option, automatic u p d a t i n g of calibration curves, and retention time correction based on internal reference peaks. Perkin Elmer 414 P o l y m e r m o d e l i n g . ChemPolymer i n t e g r a t e s polymer b u i l d i n g a n d property calculation by using inter active analysis and display functions, including spectral displays of poly mer properties. Building functions include branching, kinetic control for mixed copolymers, stereochemical control, a n d c r y s t a l l i n e packing. Physical and bulk property calcula tions are displayed as 2D spectra t h a t can be viewed alongside the polymer model and stored in data bases. Chemical Design 415
