METHODS, SYSTEMS AND DEVICES FOR PERFORMING ANALYTICAL PROTOCOLS

摘要

Methods, systems and device for performing analytical protocols are provided. Embodiments of the subject methods include sequentially contacting a sample with at least a first stationary phase and a second stationary phase under chromatographic conditions to at least determine the binding identity of the at least one constituent, where the specificity of the first stationary phase for at least one constituent present in the sample is at least uncertain and the specificity of the second stationary phase for the at least one constituent is certain. Also provided are systems and devices that include at least the first and second stationary phases. Kits for use in practicing the subject methods are also provided.
