Flexible FTIR spectrometers, such as the Thermo Scientific Nicolet line of FTIR spectrometers, can be configured to cover a wide range of performance. A part of this is spectral range as shown in this chart...
What types of sampling cells and detectors are used for protein analysis? Using the Beer-Lambert law in FTIR ATR for quantitative analysis of a time-sensitive, migrating substance (e.g., erucamide) in a polymer is difficult....
FTIR is part of the SMART chart series and is shown above with Raman, which is a complementary technique FTIR Technical Specifications Signal Detected: Infrared absorption Elements Detected: Molecular functional groups (NOT elements) Detection Limits: 1-10 wt% (quantification of known components); 5...
Note from our chart that a molecule behaves differently when exposed to these different energy levels. For example when exposed to x-ray energy a molecule will undergo nuclear transitions (i.e.. lose a neutron) or when exposed to ultraviolet energy it may undergo an electronic transition (i....
The FTIR spectrum is displayed as a chart. The vertical axis shows how much infrared light the substance absorbs. The horizontal axis represents the frequency, or wavelength, of the light. Unknown materials are identified by searching the IR spectrum against a database that has a wide range of...

Infrared spectrum chart peak positions were basically the same, and the chemical composition were roughly the same. They were composed of carbohydrate, protein, lipid and other biological molecular vibration spectrum band. From 1 800 to 1 000 cm-1 for second derivative conduction, the difference ...

Since every functional group is composed of different atoms and bond strengths, vibrations are unique to functional groups, and classes of functional groups (e.g. O-H and C-H stretches appear around 3200 cm-1and 2900 cm-1, respectively). A correlation chart with various functional group vibr...
