Ultra Low Noise Multiple Isotopx Ion Counting (IIC) and Faraday Detectors on Phoenix TIMS

Posted on 23rd July, 2021

When measuring very small ion signals (<10,000cps), in sub picogram samples of actinides, ion counting detectors are necessary due to their low noise compared to that of a Faraday detector. Ion counters however, still have a non-zero noise associated with them, known as the dark noise, which is typically several...
