FTIR (fourier transform infrared spectroscopy)
Large or small pulp and paper contaminants, process deposits
and unknown material can be identified by using FTIR techniques.
Once identified, the contaminant and its source may be eliminated.
The
infrared region of the electromagnetic spectrum is useful
in identifying unknown samples of interest. Usually an infrared
spectrum reveals the nature of unknown sample and serves
as
an excellent tool for sample identification. The FTIR spectrometer
and the FTIR-microscope are available in Econotech for identifying
macro and micro amounts of unknown samples. A few of the
applications of these techniques are now available at Econotech.

FTIR SPECTROMETER
The following techniques are available:
- KBr disc
- Pyrolysis
- NaCl salt plate
Solids, powders, liquid, plastics, rubber and extractives can
be identified using one or more of the above techniques. Samples
such as pulp and paper
process deposits,
contaminants, plastics, unknown materials, material comparison and unknown
coating material are frequently analyzed.
FTIR MICROSCOPE
A small size of sample is handled and prepared under a stereo
microscope, and subsequently transferred on to an FTIR-microscope
slide for final
infrared identification. The following techniques are available:
- Microtransmission
- Microreflectance
Micro amounts of unknown pulp and paper contaminants, paper
holes, streaks, process deposits, paper coatings, printing defects,
tape pull, fly
ash, etc. can be identified
using these techniques.
FTIR SPECTRA LIBRARIES
These libraries are available for fast and reliable
spectra identification.
