FAQs

What is the use of FTIR spectrometer? ›

FTIR spectra reveal the composition of solids, liquids, and gases. The most common use is in the identification of unknown materials and confirmation of production materials (incoming or outgoing). The information content is very specific in most cases, permitting fine discrimination between like materials.

An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time.

TEO-200 Benchtop FTIR spectrometer 1cm-1 Resolution

The Model TEO200 benchtop FTIR spectrometer is a low cost Fourier transform infrared spectrometer that employs a number of unique features to achieve high performance from such a compact size.

The Components of FTIR Spectrometers

A common FTIR spectrometer consists of a source, interferometer, sample compartment, detector, amplifier, A/D convertor, and a computer. The source generates radiation which passes the sample through the interferometer and reaches the detector.

Fourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties.

Typically, routine FTIR analyses for simple samples can be completed within a few hours to a day, including sample preparation and data acquisition. More complex analyses, especially those involving extensive sample preparation or advanced data processing, may take several days or even longer.

For well resolved peaks that are not saturated, instrument variation results in a wavenumber accuracy within 1.1 cm⁻¹ for spectral resolutions of 4 cm⁻¹ or higher and within 2.2 cm⁻¹ for spectral resolutions of 8 cm⁻¹.

FTIR detectors observe interferograms as analog signals, but in order to perform a Fourier transform, the analog signals first need to be converted to digital signals.

FTIR analysis is one analytical technique that can be used to identify toxins and contaminants in inorganic samples. For example, a company wanted to make sure that a recent shipment of beach balls was free of polyvinyl chloride (PVC) and phthalates before sending them off to be sold.

Is FTIR an imaging technique? ›

FT-IR imaging is an exceptionally useful technique to analyze the distribution of compounds in a sample or to help understand the structure of a sample. This technique has broad ranging applications whether that is in research, medicine, quality control, or failure analysis.

OMNIC Paradigm Software for desktop and touchscreen is an advanced software package for FTIR spectroscopy, designed to simplify how you acquire, process, and interpret data, and to help you work remotely and collaborate with colleagues around the globe.

FTIR is sometimes confused or blinded by water. Like Raman, it cannot see elements, simple ionic compounds, and purely ionic acids in water.

The FTIR spectrometer essentially uses an interferometer to measure the energy that is being transmitted to the sample. The infrared radiation emitted from the black body reaches the interferometer where the spectral encoding of signals happens.

FTIR basically works on the principle of absorption of an infrared light source on the sample. An intense wavelength of infrared light is passed through the sample. The FTIR instrument measures the absorption wavelengths.

Fourier Transform Infrared spectroscopy (FTIR) is a widely used technique to study a wide range of substances ranging from simple molecules to complex systems, and it is possible to analyze samples in amorphous or crystalline solid state, aqueous solutions, solvents films, potassium bromide tablets (KBr), and membranes ...

In summary, while infrared spectroscopy is a general term encompassing various methods of measuring infrared light absorption, emission, or reflection, FTIR specifically refers to a technique that uses interferometry and Fourier transformation for data collection and analysis.

Fourier transform infrared spectroscopy (FTIR) spectroscopy detects functional groups such as vibrational bands like N-H, O-H, C-H, C = O (ester, amine, ketone, aldehyde), C = C, C = N (vibrational modes of a tetrapyrrole ring) and simply C = N.
