High temperatures, voltage, acidic mobile phases, and elements (such as salts) in a sample can create a corrosive environment in the MS source that can eat away at the capillary electrode. This can cause the instrument to lose sensitivity. Long-Life ESI Electrode has been developed by Restek to prolong sensitivity of the electrode.
Long-Life ESI electrodes ensure more instrument uptime for sample analysis and are a particularly good choice for high-throughput laboratories.
