MB3600 FT-NIR Laboratory Analyzer for QA/QC

Wet-chemical conventional laboratory reference methods for acrylic acid esters are tedious, time-consuming, and expensive.

In this application note, explore how FT-NIR spectroscopy can be used successfully to determine OHv, Av, and Visco in acrylic acid esters. This methodology requires no sample preparation thus providing a quicker, cheaper, and simpler alternative for QA/QC product lots certification and release.

This application note from ABB Analytical Measurements discusses and demonstrates how ABB near-infrared spectroscopy (FT-NIR) is designed to provide a fast and efficient online crude oil characterization solution, enabling planners to optimize their processes based on accurate real-time knowledge of a given crude oil input.

In this application note, ABB Analytical Measurements demonstrates that NIR spectroscopy is nondestructive, easy to operate without sample preparation, and a fast technique to measure organic peroxides. In the study, two organic peroxides (dicumylperoxide and 2,5-bis(tert-butylperoxy)-2,5-dimethyl-hexane) were measured for three final products.

Blending powders to obtain a homogeneous product is a common procedure in the chemical and pharmaceutical industries. In this application note, ABB Analytical Measurements demonstrates how FT-NIR spectroscopy can be used to monitor blending processes and to establish when blends become homogeneous.

Acrylic acid esters are formed by the reaction of acrylic acid with alcohols. Hydroxyl value (OHv), acid value (Av) and viscosity (Visco) are commonly used to characterize and certify final acrylic acid ester products. OHv and Av provide an indication on synthesis completion, while Visco allows estimation of the molar mass of the produced monomers. In this application note, ABB Analytical Measurements performs the quantitative analysis of acrylic acid esters by FT-NIR spectroscopy by evaluating the OHv, Av and Visco.

Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic. ACH process consists of three different stages called reactor, crude, and pure product. In this application note, ABB Analytical Measurements assesses the feasibility of determination following chemical properties in the three different process stages by FT-NIR to provide real-time feedback and optimize the process. Those properties are ACH, free HCN, and diethyl amine (DEA) in reactor, water and SO₂ in crude, and acetone, acidity, water and phenothiazine (PTZ) in pure product.

Citric acid is an important organic acid used extensively in food and pharmaceutical industries. It is produced mainly by submerged fermentation and the progress of the reaction can be followed by pH titration. However, wet-chemical conventional laboratory reference methods for titration are tedious and time consuming. In this application note, ABB Analytical Measurements demonstrates the use of FT-NIR spectroscopy as a quicker, cheaper and simpler alternative for reaction monitoring.

Agar is a mixture of polysaccharides widely used in food, chemical and pharmaceutical industries for its jelly-like structure. As it is obtained from different species of red algae, its quality can vary from lot to lot. In this application note, ABB Analytical Measurements determines if NIR spectroscopy can be used to identify optimal and sub-optimal lots of powdered gelatin agar.
