“…The fast and non-destructive nature of the NIR technique has led to numerous applications in several industries (Williams & Norris 1987;Osborne et al 1993;Workman 1993Blanco et al 1998). There have been a number of NIR applications in the food (Osborne et al 1993;Reeves & Zapf 1999), forest (Schimleck et al 2004), textile (Cleve et al 2000), biomedical (Sowa et al 1999;Sasic & Ozaki 2001), petroleum (Parisi et al 1990) and chemical industries (Armenta et al 2005). Later, the pharmaceutical industry has become one of the main application areas for NIR spectroscopy.…”

The use of near infrared (NIR) spectroscopy has rapidly grown partly due to demands of process analytical applications in the pharmaceutical industry. Furthermore, newest regulatory guidelines have advanced the increase of the use of NIR technologies. The non-destructive and non-invasive nature of measurements makes NIR a powerful tool in characterization of pharmaceutical solids. These benefits among others often make NIR advantageous over traditional analytical methods. However, in addition to NIR, a wide variety of other tools are naturally also available for analysis in pharmaceutical development and manufacturing, and those can often be more suitable for a given application. The versatility and rapidness of NIR will ensure its contribution to increased process understanding, better process control and improved quality of drug products. This review concentrates on the use of NIR spectroscopy from a process research perspective and highlights recent applications in the field.

“…Near-infrared (NIR) spectroscopy has proved to be quite suitable for such applications, providing the basis for predicting several chemical and physical properties from a single sample's spectrum [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. By means of powerful multivariate techniques like partial least-squares regression (PLS), each property of interest can be regressed on the NIR absorption spectra, resulting in a calibration model that can be used to predict that property's value for a given test sample.…”

“…The feasability of using near infrared spectroscopy (NIR) [1] combined with multivariate calibration [2,3] to predict simultaneously several chemical and physical properties of petroleum products has already been widely demonstrated [4][5][6][7][8] and makes the incorporation of this technology into real-time process control systems very attractive [9][10][11]. This technique is now well known to be able to provide rapid, low cost and on-site analyses of very important worldwide commodities such as gasoline [12,13] and diesel fuel [14] and is as precise as the ASTM (American Society for Testing and Materials) methods.…”

However, moving this analytical technology from the laboratory to the factory or to the process line, has indicated the need to guarantee the performance and reliability of the analyser to avoid a possible expensive misapplication.…”

Résumé -Suivi de procédés de raffinage sur distillats moyens par spectrométrie proche infrarouge -L'objet de cet article est de démontrer la précision des déterminations physicochimiques réalisées à partir d'équations construites par analyse multivariée de spectres proche infrarouge d'une base dite de calibration. Ce type d'approche permet d'accéder simultanément à différentes propriétés à partir de la mesure d'un seul spectre enregistré en ligne ou de façon ex situ. Les 8 propriétés suivantes sont prédites dans un temps beaucoup plus court que par les méthodes conventionnelles pour des échantillons issus de l'hydrotraitement de charge de distillation directe, i.e l'indice de réfraction à 20°C, la masse volumique à 15°C, le % poids d'hydrogène, le % de carbone aromatique, les % poids en mono-, di-et total aromatiques et l'indice de cétane. L'efficacité de cette technique a été démontrée pour le suivi détaillé de l'hydrotraitement de gazole.Mots-clés : spectrométrie proche infrarouge, distillats moyens, analyse multivariée, analyse pétrochimique. Abstract -Control of Refining Processes on Mid-Distillates by Near Infrared Spectroscopy -The purpose of this paper is to demonstrate the accuracy of physicochemical determinations based on equations calculated by multivariate analysis of near infrared spectra which gives access to simultaneous analyses both on-line and off-line. Detailed results concerning the determination of the refractive index at 20°C, the density, the weight% of hydrogen, the % of aromatic carbon, the weight% of mono-, di-and total aromatics and the cetane number on mid-distillates are given in a shorter time than using the conventional approach by standardized methods. It is shown that near infrared spectroscopy combined with chemometrics should allow detailed and precise comparisons of the hydrotreatment process efficiencies.
