Direct Mercury Analysis Simplified for Academic Teaching and Research
This industry report offers examples of how universities successfully incorporated DMA-80 evo as a safe, green, effective technology for mercury determination in teaching and research programs.
FT-IR gas analysis of coal-to-ethylene glycol process
October 31st 2024Coal-to-ethylene glycol is the process by which ethylene glycol is synthesized from coal instead of traditional methods using petroleum as the raw material. This study demonstrates that Fourier Transform Infrared Spectroscopy (FT-IR) can be a reliable alternative to simultaneously measure methyl nitrite and other process gases (such as CO and NO) using a single ABB analyzer.
Sensi+, fast, accurate and reliable monitoring of H₂S, H₂O and CO₂ in natural gas
October 31st 2024Sensi+ is a compact natural gas contaminants analyzer based on a unique tunable diode laser (TDL) technology called Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS™). The technology accurately, reliably, and simultaneously measures corrosive substances such as hydrogen sulfide, carbon dioxide and water in real-time within complex and time-varying natural gas streams. Mitigating the risks and effects of contaminants in natural gas can be challenging for pipeline operators, process industries, and natural gas utilities. These companies must manage various technologies and devices to achieve a comprehensive analysis, which can be complex, prone to failure, and costly. ABB's revolutionary Sensi+™ analyzer answers these issues.
Fiber-based FT-NIR analyzer configuration for crude oil analysis
October 31st 2024This paper encompasses the FT-NIR optical configuration. The optical configuration depends on the ideal spectral range for gathering spectroscopic information about crude properties (i.e., combination vs overtone region), as well as careful selection of optical hardware to minimize residual absorption and light loss, which could be detrimental.
Polyvinyl alcohol (PVA) analysis using FT-NIR analyzer
October 31st 2024Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer used in manufacturing synthetic fabrics. It is also used as a suspension polymerization agent, as a base material in a variety of medical device applications due to its biocompatibility, and as a base polymer for additive manufacturing (e.g., 3D printing). Learn how FT-NIR spectroscopy offers a fast and non-destructive technique to determine transesterification degree during polyvinyl alcohol synthesis.
