Associate Professor Christer S. Ejsing at the University of Southern Denmark uses the TriVersa NanoMate, as an essential laboratory instrument, for the development and applications of Lipidomic technology.
New publication: Direct analysis of intact proteins from Escherichia coli colonies by LESA mass spectrometry
Researchers in the UK have demonstrated the use of Liquid Extraction Surface Analysis (LESA) on the TriVersa NanoMate for top-down identification of proteins directly from living bacterial colonies grown in Petri dishes, without sample preparation. The method offers “improved sampling precision and could be useful for spatial profiling of bacterial colonies or analysis of contaminated surfaces.”
New Video: Direct Analysis of Liquids and Solids
Direct sample analysis of liquids, solids and powders without chromatography is as easy as it sounds, and provides mass spectral information within seconds. Our new video demonstrates analysis of a reaction mixture.
Environmental Analysis: Quantitation of Perchlorate by Ion Chromatography with Supressed Conductivity on the expression CMS
The expression Compact Mass Spectrometer (CMS) provides lower detection limits and greater selectivity for Perchlorate compared to a conductivity detector (CD).
“Anyone interested in volatiles will find the CMS is an excellent instrument for targeted analysis.”
Dr. James Reynolds’s group at the University of Loughborough conducts analysis of volatiles by direct breath analysis. The expression CMS allows for highly sensitive dermination of volatile species in breath with no preconcentration.
Reaction Monitoring by Direct Analysis Probe on a Compact Mass Spectrometer
The expression CMS provides essential compound information quickly and improves the chemist’s workflow. The Atmospheric Solids Analysis Probe (ASAP) permits fast analysis of solid and liquid samples and is a simple, faster and lower cost alternative to LC/MS methods. This direct analysis probe method has been shown to be useful for the analysis of volatile and semivolatile compounds. ASAP is available as a combined ASAP-APCI source, or existing APCI sources can be easily modified to become dual APCI-ASAP capable.
“Everyone can use it, including students.”
Dr. Frédéric Schmidt’s group at the Institut Curie in Paris had previously given their samples to outside MS services for analysis and had to wait for the results. Incorporating Advion’s expression CMS into their lab allowed them to have a self-service option that everyone could use. And the new workflow sped up their process significantly.
Peptide/Protein Analysis in Less than One Minute
The expression CMS is a high performance, easy-to-use single quadrupole mass spectrometer with a small footprint to fit in space restricted labs. Priced substantially lower than other available systems, the CMS brings the analytical benefits of FIA/CMS and LC/CMS within the reach of more scientists than ever before.
Direct Mass Analysis from Solid & Liquid Samples
The expression CMS improves the chemist’s workflow by using a direct analysis probe, otherwise known as ASAP® (Atomospheric Solids Analysis Probe), to permit chemists affordable and reliable sample analysis of solid and liquid samples such as reaction mixtures, food samples, natural products and tablets.
“The CMS is a very helpful instrument that has shorten product detection times.”
Professor Meng of the Beijing Institute of Technology uses mass spectrometry as a tool for synthetic intermediates. With a large number of products to run, Meng and his team needed to shorten product detection times.
