Fourier transform infrared (FTIR) spectroscopy combined with chemometrics of partial least square (PLS) and discriminant analysis (DA) has been developed for simple analysis of lard in the mixtures with body fats of lamb (LBF), cow (Cow-BF), and chicken (Ch-BF). The spectral bands correlated with lard, LBF, CowBF and Ch-BF as well as their lard blends were scanned, interpreted, and identified. ...

Shen F., Wu Q., Su A., Tang P., Shao X., Liu B. (2016): Detection of adulteration in freshly squeezed orange juice by electronic nose and infrared spectroscopy. Czech J. Food Sci., 34: 224–232. The use of electronic nose and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) as rapid tools for detection of orange juice adulteration has been preliminarily investigate...

Fourier transform infra red (FTIR) and energy band gap of potassium lithium borate glasses of different composition have been studied using Fourier FTIR and UV-VIS spectroscopy techniques. The glasses were melted in the alumina crucible in an electric furnace at 1100°C for 30 min until homogenous melt was obtained. The X-ray diffraction analysis was adopted for confirming the amorphous nature o...

Like other optical spectroscopy methods, FTIR can provide accurate quantitative analysis for many analytes. With the proper calibration, FTIR spectra can yield both sensitive and selective determination. Although it was once common to post process data after collection, innovative software packages, such as Agilent MicroLab PC and Agilent MicroLab Mobile, provide direct reporting of quantitativ...

Cereal-based and sucrose-coated infant cereals were ground, and the sucrose, glucose, and fructose concentrations were determined with the Agilent Cary 630 Fourier transform mid-infrared, FTIR, instrument and compared to values measured by HPLC. The results indicate that use of the portable FTIR instrument was in line with the HPLC measurements, and that the Cary 630 is suitable for real-time a...

ATR-FTIR (Attenuated Total Reflectance Fourier Transform Infrared) spectra of prehardened epoxies with varying amounts of hardener and resin (mix ratio) have been acquired on a Midac FTIR spectrometer. The spectra form a set of training spectra for partial least-squares (PLS) analysis which was then used to analyze a series of epoxies of unknown mix ratio. The PLS model predicted the unknown mi...

Fourier transform infrared (FTIR) spectroscopy has long been a powerful tool for structural analysis of membrane proteins. However, because of difficulties in resolving contributions from individual residues, most of the derived measurements tend to yield average properties for the system under study. Isotope editing, through its ability to resolve individual vibrations, establishes FTIR as a m...

The determination of toxic components from fire gases is difficult because the environment is hot, reactions are often temperature dependent, and a lot of soot may be produced. Due to the different properties of the gas components, a different timeconsuming procedure for each species has traditionally been used. The use of FTIR (Fourier Transform InfraRed) spectrometers as a continuous monitori...

BACKGROUND Sentinel lymph node (SLN) biopsy is a routine surgical staging procedure in clinically lymph node-negative breast cancer. Fourier transform infrared (FTIR) spectroscopy, a technique based on the biochemical composition of the tissue, has previously been found to be capable of differentiating between normal and malignant tissue. The aim of the present study was to explore the intraope...
