Pseudo-continuous flow ftir system for glucose, fructose and sucrose identification in mid-ir range
Micromachines, 2018•mdpi.com
In this paper, we present a new FTIR-based microfluidic system for Glucose, Fructose and
Sucrose detection. The proposed microfluidic system is based on a pseudo-continuous flow
coupled to a microscope-FTIR instrument. The detection and characterization of sugar
samples were performed by recording their absorption spectrum in the wavelength range
700–1000 cm− 1 of the Mid-IR region. The proposed pseudo-continuous flow system is
designed to improve the uniformity of the sample distribution in the analyzed area versus …

In this paper, we present a new FTIR-based microfluidic system for Glucose, Fructose and Sucrose detection. The proposed microfluidic system is based on a pseudo-continuous flow coupled to a microscope-FTIR instrument. The detection and characterization of sugar samples were performed by recording their absorption spectrum in the wavelength range 700–1000 cm−1 of the Mid-IR region. The proposed pseudo-continuous flow system is designed to improve the uniformity of the sample distribution in the analyzed area versus conventional systems. The obtained results for different sugars concentrations, show a very low measurement error of 4.35% in the absorption peak intensity, which is ten times lower than the error obtained using the conventional measurements.
