How to clean the Focus Electrodes for an ESI and DUIS Unit on a LCMS-8060NX

In this how-to video, we'll walk you through the essential steps for cleaning the focus electrodes on your LCMS-8060NX system, specifically for Electrospray Ionization (ESI) and Dual Ionization Source (DUIS) units. Overtime the focus electrodes can become soiled showing a decrease in transport efficiency and detection sensitivity. When this is observed, cleaning of the focus electrodes will be needed with the addition of the corona needle if it is a DUIS unit.
Join us as we demonstrate a detailed, step-by-step process for safely and effectively cleaning the focus electrodes. We'll provide practical tips and best practices to ensure thorough cleaning without damaging sensitive components. Whether you're a seasoned LCMS operator or new to mass spectrometry maintenance, our comprehensive guide will empower you to perform this critical task with confidence.
Keep your LCMS-8060NX system operating at its best by following our maintenance tutorials. Subscribe to our channel and hit the notification bell to stay updated on the latest tips and tricks for optimizing your mass spectrometry workflow.
