A robotic system for handling components during chromatographic analysis of a sample includes a holder for positioning a sample within a separation pathway, the holder including a first opening having an internally tapered shape and a second opening having an externally tapered shape. An interior of the holder, between the first and second openings, defines the separation pathway. A hollow rigid member has an externally tapered shape, and a receiving portion has an internally tapered shape. The holder is positioned between the hollow rigid member and the receiving portion, wherein the externally tapered hollow rigid member engages the internally tapered first opening and the internally tapered receiving portion receives the externally tapered second opening to provide a sealed separation pathway extending from the hollow rigid member to the receiving portion.

System useful for holding a sample and in subjecting the sample to chromatographic analysis

The present invention relates generally to the field of analyzing proteins and more specifically to the reduction and alkylation of protein samples during protein analysis. A novel composition and method for reducing and alkylating proteins is disclosed. A novel reagent including a combination of a volatile reducing agent, a volatile alkylating agent, and a volatile solvent is used for a one-step reduction and alkylation of proteins allowing the protein sample to remain in the same container during the reduction and alkylation processes.
