greatly applications

Least squares, polynomial, and logarithmic curve fitting integrate with other ASYST

simplifies like EPR

exponential, routines fully capabilities.

Sophisticated graphics integrate theoretical analysis. On-screen and presentation-quality output

with ASYST labeling are easy.

With ASYST, data acquisition and analysis routines can be combined in powerful chemical applications, such as Raman spectra.

ASYST Scientific Software. Acquisition, analysis and graphics capabilities turn your IBM PC into a powerful workstation. ASYST a n d y o u r IBM PC, XT," AT, or c o m patible put you in direct c o n t r o l . You can create a p p l i c a t i o n s as specific as y o u need, using the built-in p o w e r of ASYST routines to pull i n f o r m a t i o n t h r o u g h the analytical process. N o w , f o r the first time, you have c o m p l e t e i n t e g r a t i o n on y o u r d e s k t o p .
