Rugged Long-Life ESI Electrodes Provide OEM-Equivalent Results and Longer Lifetimes

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.

Restek to Present “Gas Chromatography: Foundation Theory, Column Selection, and Troubleshooting” at GC-MS Seminar

Chromatographers from Restek will be presenting at Waters’s upcoming seminar on October 23, 2019, in Wood Dale, IL. This educational opportunity is aimed at scientists looking to learn more about GC-MS capabilities in all areas, particularly in food and environmental applications. Topics include the technology behind GC-MS instruments, QuEChERS sample preparation, identification of extractable and leachable compounds from electronic cigarettes, and multiresidue pesticide analysis. Register today and join us for an outstanding technical training event.

Restek Presentation
Gas Chromatography: Foundation Theory, Column Selection, and Troubleshooting
This course is a solid initiation into the fundamentals and best practices of this widely used technique. You will gain practical knowledge of the principals of gas chromatography, and GC column selection, as well as maintenance and troubleshooting.

Abstract: Three types of polyethylene glycol (PEG) columns from different vendors were evaluated to determine which performed best for the analysis of glycols in water. The columns were first challenged with exposure to 600 aqueous injections and then linearity, lifetime, and bleed were assessed. Rtx-Wax columns performed well throughout the test and were the only columns that passed all tests.

Abstract: Dietary supplements, which are consumed worldwide, are made from various botanical ingredients. To be safe from pesticides exposure, residual pesticides must be monitored by chromatographic instrumentation. Issues arise, however, due to the fact these botanical samples are dried and cause large interferences in the chromatography. This study shows that the modified QuEChERS method combined with GC-MS/MS achieves consistent pesticides monitoring in botanical ingredients.
