Software Structure
To reduce complexity of operation the software is divided into specific
applications, called modes. In addition levels of operation are available and
support for data evaluation sessions without spectrophotometer control.
Agilent ChemStation Sessions
Your Agilent ChemStation belongs to the Agilent's ChemStation family of
instrument control software. An installation of Agilent ChemStation software
can control up to four different UV-vis instruments based on a single PC. Each
of these instruments has its own session
If you start a session, its name is indicated in the main application's window
title bar, for example, Agilent 845x UV-visible System[1].
Each instrument session is available for data analysis only and for instrument
control. An instrument control session has the appendix (Online) and can be
started as the first instance only on your PC. In addition a data analysis
sessions, which has the appendix (Offline), can be launched. The offline
session allow recalculations based on stored data and is useful in the
