the nondestructive techniques are applied to identify important data from the internal process of distillation towers, process towers, pressure vessels and etc. in recent, the gamma-ray scanning techniques as diagnostic tools for scanning of tray columns, packed columns, storage tanks, level measurement and density measurement of containing materials has been used widely. this paper has tried t...

Introduction: Rapid identification of cocoa bean varieties is vital for the authentication in cocoa trade. This paper examines the use of Near Infrared (NIR) Spectroscopy for nondestructive identification of cocoa bean cultivars. Methods: In this study, five cocoa bean cultivars (IMC85 x IMC47, PA7 x PA150, PA150 x Pound7, Pd10 x Pd15 and T63/967 x T65/238) were scanned in the NIR range of 1000...

The contents of hemicellulose, cellulose and lignin are important for moso bamboo processing in biomass energy industry. The feasibility of using near infrared (NIR) spectroscopy for rapid determination of hemicellulose, cellulose and lignin was investigated in this study. Initially, the linear relationship between bamboo components and their NIR spectroscopy was established. Subsequently, succ...

oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...

Near-infrared (NIR) spectroscopy and imaging are fast and nondestructive analytical techniques that provide chemical and physical information of virtually any matrix. In combination with multivariate data analysis these two methods open many interesting perspectives for both qualitative and quantitative analysis. This review focuses on recent pharmaceutical NIR applications and covers (1) basic...

Automatic control of a fluidized-bed drying process depends on the availability of an inline sensor to provide accurate measurements of product moisture content. Nearinfrared (NIR) spectroscopy technology provides a potentially noninvasive and nondestructive analytical method that could serve as a sensor option for a wide range of applications. The purpose of this research was to investigate th...

For several years, near-infrared spectroscopy (NIRS) has become an analytical technique of great interest for the pharmaceutical industry, particularly for the non-destructive analysis of dosage forms. The goal of this study is to show the capacity of this new technique to assay the active ingredient in low-dosage tablets. NIR spectroscopy is a rapid, non-destructive technique and does not need...
