Piccaro, Inc. announced an ultra-trace gas analyzer for precisely measuring isotopic CO2, a marker of the type of CO2, and its origin. The instrument is based upon cavity ring down spectroscopy (CRDS) technology, exclusively licensed from Stanford University, Stanford, California and further enhanced at Piccaro.
The CRDS analyzers deliver parts-per-billion to parts-per-trillion gas sensitivity at high speed and without interference. The isotopic CO2 application was developed for the Los Alamos National Laboratory, Los Alamos, New Mexico, where the instruments were used to study CO2 ratios and concentrations in plants and the atmosphere.
Isotopic CO2 applications also can include the monitoring of carbon sequestration and measuring mud-gas samples collected during the natural gas exploration process. Carbon sequestration is a process of capturing carbon emissions from power plants, compressing them, and putting them underground instead of into the atmosphere. Mud-gas analysis is done to help energy service providers pinpoint the quality and potential quantity of natural gases.
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.
