Methods and apparatuses dynamic range enhancement of fluorescence detectors are described herein. In one aspect, a method can include collecting, from a sample during a sample event, an emission spectrum that comprises a plurality of emission signals; based on reception times associated with emission signals of the plurality of emission signals, determining a lifetime estimation for the sample; determining, based at least on the lifetime estimation, a pileup factor affecting receiving emissions from the sample; and based on the determined pileup factor, adjusting a number of emission signals measured during the sample event to generate an estimated number of emissions for the sample event.

This paper provides a method for detecting low concentrations of amphoteric compounds in a sample, comprising: (a) preparing an analytical sample mixture for capillary isoelectric focusing (CIEF) detection using the sample; and (b) detecting the analytical sample mixture using a fluorescence detector via a CIEF system; wherein the concentration of the low concentration amphoteric compound in the analytical sample mixture is less than 0.5 μg / μL. This method is more resistant to background noise interference and can sensitively detect and accurately quantify low concentrations of amphoteric compounds present in the sample.
