Longer sensitivity in high-throughput LC-MS

Restek Corp.

Rugged long-life ESI electrodes provide equivalent LC-MS/MS performance to OEM electrodes over significantly longer lifetimes

Product news

The harsh environment inside an MS source takes its toll on ESI electrodes, and once they corrode, sensitivity drops, runs fail, and productivity halts while the instrument is offline for maintenance.

To help labs overcome this obstacle, Restek has developed the Long-Life ESI electrode for Sciex Turbo V sources, which is more rugged than original equipment manufacturer (OEM) electrodes. Testing shows that Long-Life ESI electrodes provide equivalent LC-MS/MS performance to OEM electrodes over significantly longer lifetimes. Because they perform the same and are less susceptible to corrosive conditions in the MS source, Restek Long-Life ESI electrodes ensure more instrument uptime for sample analysis and are a particularly good choice for high-throughput laboratories.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.

Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.
