Abstract: Disclosed are methods, apparatuses, and systems, for (1) providing reliable identification of analytes from an HPLC or other analytical instrument, (2) ensuring data integrity during transfer of analytical data from the instrument to, for example, a control application or other destination, and (3) near-immediate transfer of the data after analysis. Embodiments include methods, apparatuses, and systems that automatically identify a subset of analytes from a plurality of analytes able to be analyzed by a liquid chromatograph (or similar instrument) and that automatically extract a subset of result data from the instrument, where the result data relates to a liquid mixture sample from a reactor (or other source) and where the subset of data corresponds to the subset of analytes. The subset of data may then be used to control a reactor process, or other process, by, for example, transferring the subset of data to a control application.
