Abstract
The present disclosure is directed to an auto-sampling system with syringe, valve configurations, and control logic that allow automatic, inline preparation of concentrated sulfuric acid and concentrated phosphoric acid for analytic analyses. In implementations, the auto-sampling system includes independent syringe pumps connected to a valve system to dynamically introduce carrier, diluent, buffer, and eluent flows according to one or more modes of operation.
