Introduction
ReactIR™ 45m is an FTIR-based, high performance, in situ reaction analysis system
designed specifically for the chemist and chemical engineer who require the highest level of
precision for kinetic studies and quantitative analysis. It provides real-time information on the
effect of changing reaction conditions such as solvent, catalyst, temperature, and reagent
addition rate, saving valuable resources. Based on the information provided by ReactIR 45m,
scientists are able to correlate, in real time, the impact of varying reaction conditions to
reaction performance—dramatically reducing development time.
This document contains a pre-installation checklist for site preparation, technical
specifications, system configurations, instrument installation and system readiness testing,
routine operation, safety information, as well as care and maintenance information,
troubleshooting tips, and a glossary.

Pre-Installation Checklist
This chapter outlines the end-user’s responsibility to ensure a successful installation of the
ReactIR™ 45m system and provides information about physical and utility requirements. The
Field Service Engineer (FSE) responsible for performing system installation will send the link
to this document upon initial shipment of system to allow adequate time for site
preparation.The document is on the AutoChem Customer Community website.
Use this chapter of the document as a checklist to verify that all prerequisite steps have been
completed before a scheduled ReactIR 45m system installation. Items on this checklist must
be completed prior to scheduling a date for system installation with a METTLER TOLEDO Field
Service Engineer.
If you have any questions or need assistance please contact AutoChem Customer Care using
the information on page 9. Refer to Chapter 5 on page 29 for detailed system specifications.
[ ] Site Preparation
Complete the following sections to prepare your site for safe, fully functional use of the ReactIR
45m.
[ ] Space and Weight Requirements
A ReactIR 45m system can be installed on a bench top or inside a fume hood. Allow space
for the base unit with power supply as well as room to maneuver the sampling technology
for reaction analysis. Also, allow adequate space for the control computer.
*Overall system dimensions will vary depending on the selected sampling technology and
do not include the footprint of the control computer.
Note:
Access to the site requires a password that you can request from the home
page, https://community.autochem.mt.com. Setting up access during pre-
installation will facilitate software license activation, which is also done
through the AutoChem Customer Community site.

[ ] Area of Intended Use
The area of intended use requires compliance with the following statements:
The ReactIR 45m system is designed for use in a non-hazardous area in accordance
with governmental bodies in the country of use (see Chapter 4, “Safety”).
System must have adequate benchtop space for conduit and probe
• Fiber probe should not bend beyond 30 centimeters (approximately one foot).
• Probe conduit should not be put into an “S” shape.
System should be:
• Convenient for access at eye level
• Readily accessible for service
If your Standard Operating Procedure (SOP) includes a fume hood, ensure it is installed
prior to the scheduled instrument installation.
The ReactIR 45m should not be placed directly under an air duct or vent which would
expose the system to direct airflow and extreme temperature ramps.
The ReactIR 45m should be placed in a location with minimal vibration present (that is,
no large pumps with heavy vibration on the same bench top).
[ ] Environmental Conditions
Exceeding the maximum allowable ambient temperature and humidity will negatively impact
the instrument performance and reaction monitoring data. For proper system stability and
functionality, adhere to the environmental specifications.
[ ] Utilities
ReactIR 45m systems require AC power, instrument air/gas, and communication utilities as
described below.
Note:
The ReactIR 45m base unit should not be placed directly under an air duct
or vent which would expose the system to direct airflow and extreme
temperature ramps. In addition, the ReactIR 45m should be placed in a
location with minimal vibration present (that is, no large pumps with heavy
vibration on the same bench top).

A ReactIR 45m system uses METTLER TOLEDO proprietary software, iC IR, to assure infrared
data collection and analysis possible without the need for an expert. iC IR is the result of many
years of evolution through valuable customer feedback that offers powerful reaction analysis
functions with an easy-to-use user interface. As a wizard-based application, iC IR guides you
through the experience of collecting, analyzing, and visualizing data for real time insight into
your chemistry. In essence, iC IR allows chemists to focus on solving chemistry problems
instead of instrumentation and analysis procedures.
See Chapter 4, “Safety” for safety-related information.
Definition of Terms
Refer to Appendix B on page 103 for the terms used throughout this manual and in the control
software for a ReactIR 45m system.
ReactIR 45m System Diagram
The diagram below identifies the components necessary to build up a ReactIR 45m system,
essentially what hardware the customer purchases from METTLER TOLEDO according to
specifications to install and implement the system. Components include the base unit,
computer, communication cable, power cable, and sampling technology.
Figure 3-1 ReactIR 45m system diagram
Note:
This manual uses DS to refer to either DS or DST sampling technology.
DS is an abbreviation for D Sub-miniature, which describes the D-shaped
connector at the end of the sampling technology that connects to the
ReactIR 45m base unit. The DS or DST designation refers to the design
of the probe tip.

METTLER TOLEDO
The Table 3-1 describes the internal components of a ReactIR 45m base unit: We include the
definitions for an understanding of the components that METTLER TOLEDO representatives
discuss with you during initial training, follow-up service or preventive maintenance. By
design, the ReactIR 45m will not require the user to know the location for alignment or
replacement of these components.
ReactIR 45m Sampling Technology Configurations
This section describes the sampling technology options available with ReactIR 45m.
"DS FiberConduit Probe"
