FT-IR/Raman Training Course
Overview
Description:
The FT-IR/Raman Training Course is designed for those users new to data acquisition and sample preparation. Laboratory teaching emphasizes measurement using various sampling accessories and spectral manipulations with the OPUS software. Three optional special topics are given on Thursday on specific advanced techniques.
The course will consist of lectures, laboratories sessions, and demonstrations which emphasize basic principles of FT-IR instrumentation, data processing, sampling techniques, the OPUS/IR PC software, and introductory instrument maintenance and troubleshooting.
Topics:
- Overview of NIR
- Introduction to Matrix-F, process probes and accessories
- Best practices for installation and operation of inline equipment
- CMET process software
- Sampling theory
- Process (I/O) communications
- Instrument diagnostics and maintenance
- OPUS/CMET Software
- Basic maintenance procedures
- Discussion with service personnel
Prerequisite:
一个working knowledge of the Windows XP or Windows 7 operating system and a familiarity with your Bruker FT-IR and FT-Raman instrument. The basics aspects of the operating system (e.g. copying files, formatting disks, installing printers) can be practiced in the tutorials provided with the operating system.
Please bring your laptop with OPUS software installed if available.
