AbstractPoor-quality medicines are a major problem for health-care systems in resource-poor settings as identifying falsified medicines requires a complex laboratory infrastructure such as a Medicines Quality Control Laboratory. We report here an evaluation of a low-cost, handheld near-infrared spectrometer (NIRS) device by analyzing a library of artemisinin-based combination therapy (ACT) medi...

Near infrared (NIR) spectroscopy is now a widely-used technique in the field of forest products, especially for physical and mechanical property determinations. This technique is also ideal for the chemical analysis of wood. There has been a growing need to find a rapid, inexpensive and reliable method to distinguish between preservative-treated and untreated waste wood. It has been demonstrate...

Abstract Visible and near infrared (VIS-NIR) spectroscopy is a non-destructive, fast, practical reliable technique to determine maturity quality attributes in apple fruit. However, the effects of cultivar growing conditions on predictive performance equipment must be determined before its commercial application industry. This study was carried out evaluate efficiency VIS-NIR portable spectromet...

This study focused on the use of Near InfraRed (NIR) Spectroscopy to address lack tools and skills for wood identification Dalbergia species from Madagascar. Two sample sets 41 blocks cores belonging four (D. abrahamii, D. chlorocarpa, D.greveana, pervillei) were collected in northern western regions Sapwood heartwood NIR spectra measured onwood at 12% moisture content by using a portable VIAVI ...

Both the increasing volume and diversity of drugs-of-abuse encountered by investigation services necessitates need for fast on-scene detectors to detect identify a broad range substances. Near-Infrared (NIR) spectroscopy is suitable presumptive drugs testing miniaturized sensors implemented in portable devices. Currently, myriad different NIR spectrometers available that utilize wavelength rang...

Abstract. Mining can cause severe disturbances to the soil, which underpins viability of terrestrial ecosystems. Post-mining rehabilitation relies on measuring soil properties that are critical indicators health. Soil visible–near-infrared (vis–NIR) spectroscopy is rapid, accurate, and cost-effective for estimating a range properties. Recent advances in infrared detectors microelectromechanical...
