Recent Advances in Oligo Purity and Sequence Determination by LCMS

With demand for chemicals growing at a much faster rate than the demand for transportation fuels, companies are exploring opportunities to configure their complex refineries into COTC plants. In lieu of producing transportation fuels, these COTC plants can convert crude oil directly to chemical feedstocks.

Combustible dust poses a hazard to numerous industries, such as food, wood, chemical, plastics, and metals. Dust fires and explosions are relatively rare, but when they occur, they can be catastrophic. The first step to ensure safe operations involving combustible dust is to conduct a dust hazard analysis. This webinar will provide viewers with a guide to identifying combustible dust hazards in manufacturing facilities. The topics will include developing a dust sampling plan, principles of dust clouds and ignitable atmospheres, and mechanics of dust flash fires and explosions. The webinar will then cover how to analyze processes and buildings to determine where dust fire and explosion hazards exists by evaluating normal and abnormal operating conditions, potential ignition sources, and existing safeguards in place.

Nanocellulose is an interesting material with unique properties and chemistry. Cellulose, the structural component of the primary cell wall of green plants, is the most abundant organic material on the planet and because of its useful materials properties it is one of the most widely used substances.

Minor, trace and ultratrace elemental analyses in a variety of geological and petrochemical materials are characterized by difficulties, due to the complexity of their compositions, in obtaining a complete digestion. Traditionally, academic researchers have used a variety of analytical instruments and sample preparation techniques, including open vessel digestions, Parr Bombs, flux fusion, and combustion and closed-vessel microwave digestion to prepare samples for ICP or AA analysis. While these techniques have been somewhat effective, they do pose several limitations for multi-element analysis—temperature and pressure limitations, incomplete digestions, contamination, and time consumption.
