Overview

The Bruker Fourier Transform InfraRed (FTIR) Spectrometer allows for chemical mapping and chemical identification of particles and small molecules. This technique uses an IR beam to vibrationally excite molecules within the sample, which can then be identified based on their characteristic vibrations.

The main bench is a Vertex 70 is capable of Transmission, Attenuated Total Reflectance (ATR; diamond crystal) or Grazing Angle work.

The FTIR is also equipped with a Bruker Hyperion 3000 Microscope that is fully automated, with modern focal plane array detector technology. The microscope is equipped with 4 objectives (15x Reflectance, 15x Visible, 20x ATR and 15x Grazing Angle), which can be used to collect single spectra or image.

An High-Throughput Screening (HTS) well-plate accessory is also available for high volume readings of samples within reflectance or transmission mode. For analysis, approximately 1-20 µl of a liquid sample are placed on a single sampling position of the microplate and dried. The sample volume prepared depends on sample form, measurement mode and sample plate design. For solid samples, they should be dried and ground when filling into a microplate well.

All elements and analysis are performed by the Bruker OPUS software.
