Ph. Eur. 2.2.48 Raman Spectroscopy: How Raman instruments from Metrohm comply with the 2022 update
The European Pharmacopoeia (Ph. Eur.) is a single reference work for the quality control of medicines. Ph. Eur. contains norms, suggests analytical methods, and lists many properties that define quality control (QC) during the production of medicines, the raw materials used, and the instruments required to perform such tests. These official standards are legally binding in several countries ...

Ultrasonic Characterization of Porosity In Powder Metals
Abstract We present preliminary results of a project aimed at investigating ultrasonic techniques to measure the bulk density, pore size, and spatial variation of porosity in powder metal specimens. Specific techniques considered are ultrasonic wavespeed, attenuation and wave dispersion measurements, and the identification of spectral features in the amplitude spectra. Also discussed is the ...

Firmness evaluation of melon using its vibration characteristic and finite element analysis
Analysis of the vibration responses of a fruit has been suggested as a non-destructive measure of its elastic properties (firmness). In this study, 'Huang gua' melons were excited using three types of balls (wooden, steel and rubber) and the vibration was detected by an accelerometer. The modulus of elasticity of the inner, middle and outer portions of melon flesh were determined using flat plate ...

Near-infrared spectroscopic assessment of contamination level of sewage
We examined the use of near infrared (NIR) spectroscopy as a rapid technique for the evaluation of sewage quality. Influent water samples, primary sedimentation tank water samples, and final effluent water samples were collected from sewage treatment facilities in Nagoya, Japan and their NIR spectra obtained. Partial least squares (PLS) models for total phosphate (TP), total nitrogen (TN), ...

Fluorescence imaging of nanobiomaterials: Thioflavin T in electrospun poly(vinyl alcohol) fibres
Nanoindentation has been widely used to characterise the mechanical properties of various materials. As an alternative, we recently explored a new technique with which the Young's modulus of soft materials can be obtained using environment–sensitive fluorescent dyes. The fluorescence technique has an advantage over nanoindentation in that it can non–destructively measure the physical property of ...

New Advances in XRF Technology Allow for Measurement of Electroless Nickel Plating
Electroless nickel (EN) plating was introduced over 50 years ago as a means to provide lightweight materials for improved fuel efficiencies, greater corrosion performance and durability. Quickly implemented into the automotive, aerospace and transportation industries, it was also seen as an alternative to plating with chrome, because of its ability to meet engineering requirements for ...

Present Status and Future of Advanced Scientific Instrument using X-ray
X-rays have attracted a lot of attention as a form of electromagnetic radiation that enable us to see objects through materials. And they are also a great contributor to clacification of physical phenomena. In the field of analysis, X-rays have drawn attention from their initial stage as a method of non-destructive simultaneous anaysis. Scientific measurement using X-rays is supported by three ...

Application of the standard porosimetry method for nanomaterials
A new method of Standard Porosimetry (MSP) for investigation of any type of porous materials, including soft, frail, amalgamated materials, films and powders has been developed. The method is relatively simple and non-destructive and can be used for measurements in a wide range of pore sizes from 0.3 nm to 3×106 nm. The method is currently being used to study porous materials such as carbon ...

Effects of maturity on chlorophyll-related absorption in nectarines, measured by non-destructive time-resolved reflectance spectroscopy
The ripening of fruits like nectarines and peaches is characterised by the decrease in chlorophyll content or colour of the fruit flesh. However, measuring the colour of fruit flesh is usually not conducted, as there is a lack of suitable techniques. Time-Resolved Reflectance Spectroscopy (TRS) is a novel technique that can measure the light absorbed by the fruit flesh. Using a laser light beam ...

Case study - Washington Suburban Sanitary Commission
After WSSC began experiencing major PCCP failures in the 1970s, it developed a strong commitment to infrastructure management technology in favor of large capital replacements. Beginning in 2007, WSSC and Pure Technologies began a partnership to create a comprehensive PCCP management program. The Washington Suburban Sanitary Commission (WSSC) is the 8th largest water and wastewater utility in ...
