Thermo Fisher Scientific (TMO) Releases New Whitepaper: Optimizing Mobile Phase Solvent Purity for LC/MS


7/23/2012 12:13:46 PM

LOUGHBOROUGH, England (23rd July, 2012) – Thermo Fisher Scientific Inc., the world leader in serving science, has published a white paper entitled “Optimizing mobile phase solvent purity for LC/MS.” Enhanced sensitivity and mass accuracy in liquid chromatography/mass spectroscopy (LC/MS) is essential when analytes are found in trace amounts. Purity is a crucial consideration when selecting appropriate solvents for use in such analyses, where background noise must be minimal. Optimizing the quality of mobile phase solvents can contribute to improving the chromatographic or mass spectroscopic properties of the analyte, as well as the overall detection limits of the instrument system. The whitepaper highlights the low mass background, metal ion content, contamination and LC/UV response, using diode array detection, that is possible when using the Fisher Chemical Optima LC/MS solvent range instead of other solvent brands.

Examining LC/MS solvents offered by seven companies, including Thermo Fisher, the white paper presents comparative chromatographic data from four different advanced LC/MS instruments. Data collected includes mass baseline, signal intensity, contamination by PEG and plasticizers, and metal ion content, all of which impact on the ease of MS interpretation. This data suggests that the Optima LC/MS solvent range is best for mobile phase purity.

Optima LC/MS solvents are manufactured and packaged using proprietary techniques to ensure exceptionally low metal ion content and minimal MS background noise. They also offer lot-to-lot consistency and extended column life due to low residue levels, setting the standard of excellence for consistent, reproducible performance in the mobile phase of advanced LC/MS systems.

The white paper can be downloaded at: http://www.thermo.com/eThermo/CMA/PDFs/Various/File_52953.pdf.

For more information on the Optima LC/MS reagents and other Fisher Chemical products, please visit www.acros.com or contact a local Fisher Chemical distributor.
