This article introduces ways to improve the throughput of ICP-MS analysis of environmental samples, including using the 7500ce ICP-MS to optimize sample uptake and rinse time through various techniques, as well as using new rinse modes to improve productivity.
High throughput in Inductively Coupled Plasma Mass Spectrometry (ICP-MS) depends on rapid sample wash-in/wash-out and fast data acquisition. This document focuses on maximizing productivity for the Agilent 7500 Series ICP-MS by optimizing the conventional sample introduction system, minimizing acquisition time, and utilizing intelligent software functions.
The text details methods to reduce run-to-run times, such as optimizing plumbing volume, using Pre-emptive Rinse to eliminate probe waiting time, and employing Intelligent Rinse to terminate washing based on background levels rather than fixed timers. These techniques allow for the analysis of complex environmental samples in approximately 4.5 minutes.

By combining optimized plumbing and intelligent rinse functions, typical average run-to-run times for complex environmental samples can be reduced by almost 50%.
Intelligent Rinse monitors the background level of selected elements and terminates rinsing once sufficient washing has occurred, rather than using a fixed time.
