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.
Prerequisite:
A working knowledge of the windows 10 operating system 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.
Costs:
$ 2,100
(includes course materials)
If your Bruker FT-IR or FT-Raman spectrometer has been installed within the last 12 months, one tuition is normally included as part of your purchase (please refer to your system quotation).
