Although the near-infrared (NIR) was the first non-visible region discovered in the absorption
spectrum (by Herschel in 1800) 1–3 analytical chemists made little use of it until the 1950s …

In the near-infrared region the absorption process is associated with the overtone and
combination bands of vibrational transitions. This region can be studied with the same …

Near-infrared spectroscopy is evaluated as an on-line technique for monitoring the
homogeneity of a pharmaceutical blend during the blending process. Blends containing …

This work was aimed at the investigation of the use of near-infrared spectroscopy (NIRS) for
the identification of counterfeit drugs. The identification is based on the comparison of the …

Near-infrared (near-IR) spectroscopy was used in the determination of three parameters of
theophylline tablets film-coated with ethylcellulose. Spectra of individual intact tablets were …

Near Infrared (NIR) spectroscopy is seen as a very powerful tool in a variety of applications
involving powder characterisation. Here we deal with a typical pharmaceutical application of …

Near-infrared (near-IR) spectroscopy was used to qualitatively assess the homogeneity of a
typical direct compression pharmaceutical powder blend consisting of hydrochlorothiazide …

Purpose. The purpose of this study was to investigate the potential of near-infrared (near-IR)
spectroscopy for non-destructive at-line determination of the amount of polymer coat applied …

A rapid, noninvasive, and nondestructive method for determining moisture in sealed freeze-
drying vials is described. The method, based on near-infrared spectrometry, used a novel …

Near infrared transmittance spectroscopy was used to determine the analgesic paracetamol
in a pharmaceutical preparation commercially available as tablets. Spectra were recorded …
