Agilent 500 Ion Trap LC/MS System Fast Polarity Switching Technical Overview

About this manual

This document provides a technical overview of the fast ion polarity switching feature available on the Agilent 500 Ion Trap LC/MS System. The system is capable of changing polarity every 200 milliseconds, which allows for the observation of both positive and negative ions in real time. This speed is significantly faster than many competitive systems that require over one second to switch, making them less effective for real-time dual-polarity detection.
