Biofuel production requires monitoring of feedstocks, fermentation processes, and finished products to assure yield and final quality of alternative fuels.
Biofuel production requires monitoring of feedstocks, fermentation processes, and finished products to assure yield and final quality of alternative fuels. The Thermo Scientific Dionex ICS-5000 ion chromatography (IC) system is ideal for measuring carbohydrate contents of feedstocks like corn stover, alcohol and glycol levels of fermentation solutions, and anionic contaminants such as chloride and sulfate in alcohols and biodiesel.
While ethanol has many benefits as an alternative to petroleum, it has higher vapor pressure, higher affinity for water, and lower energy content than gasoline. High blending ratios of ethanol with gasoline require modified engines, and the lower energy content reduces vehicle gas mileage. In addition, ethanol production places greater demand on the food and feed commodity markets.
Biobutanol overcomes many of these drawbacks. It can be created from cellulosic biomass as well as annual grain crops. It has lower vapor pressure, lower water solubility, and higher energy density than ethanol. It can be blended at any point in the supply chain, and increases vehicle gas mileage.

The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
Using Chromatography to Explore Fluorescent Bioactive Compounds in the Coelomic Fluid of Earthworms
February 6th 2025A study aiming to identify fluorescent bioactive compounds in the coelomic fluid of earthworms, as well as to investigate their structural and functional characteristics for possible use in biomedical applications, utilized a variety of chromatographic techniques.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
