NIR prediction of fruit moisture, free acidity and oil content in intact olives

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Determination of moisture content in lyophilized mannitol through intact glass vials using NIR micro-spectrometers

Determination of moisture content in lyophilized solids is fundamental to predict quality and stability of freeze-dried products, but conventional methods are time-consuming, invasive and destructive. The aim of this study was to develop and optimize a fast, inexpensive, noninvasive and nondestructive method for determination of moisture content in lyophilized mannitol, based on an NIR micro-sp...

Rapid Prediction of Moisture Content in Intact Green Coffee Beans Using Near Infrared Spectroscopy

Moisture content (MC) is one of the most important quality parameters of green coffee beans. Therefore, its fast and reliable measurement is necessary. This study evaluated the feasibility of near infrared (NIR) spectroscopy and chemometrics for rapid and non-destructive prediction of MC in intact green coffee beans of both Coffeaarabica (Arabica) and Coffeacanephora (Robusta) species. Diffuse ...

Optical path length and wavelength selection using Vis / NIR 1 spectroscopy for olive oil ’ s free acidity determination

Four different optical path lengths, namely 0.5, 1, 5 and 10 mm, were assayed for 8 olive oil’s free acidity determination using Vis/NIR spectroscopy. Results illustrated 9 that the use of higher path length during spectra acquisition resulted in more accurate 10 PLS models, especially when using solely the NIR region. The PLS model obtained 11 with the NIR spectrum using the 10 mm cuvette was ...
