The present disclosure relates to methods for high throughput analysis of analytes such as polypeptides in a cyclic manner (e.g., using NGPA or NGPS described herein) that allow adjustment of the dynamic range and sensitivity of analyte detection, for instance, based on the abundances of different polypeptides present in a sample to be analyzed. The approaches proposed herein can be used to adjust the dynamic range of abundant analytes (e.g., polypeptides present in high concentrations) in biological samples, such as plasma samples, and to increase proteome coverage achieved by high throughput protein analysis methods, for instance, by improving the sensitivity of detecting less abundant analytes.
