Data processor for use in chromatographic analysis
First Claim
1. A data processor for use in chromatographic analysis in which a sample is injected into a separation column and is detected by a detector, comprising:
- a first data collecting section which, for each sample injection, collects and records a detector output at every data sampling pitch T1; and
a second data collecting section which collects and records the detector output and a monitor output indicating an analysis-associated condition at every data sampling pitch T2 over a period from the start to the end of the chromatographic analysis, wherein the data sampling pitch T1 is shorter than the data sampling pitch T2.

Abstract
The present invention provides a data processor that not only makes it possible to analyze chromatograms in detail but can also collect analysis-associated information necessary for verification of data validity throughout the entire analysis process, even in cases where many samples are successively injected into a chromatography apparatus over a long period of time. The data processor comprises: a first data collecting section which, for each sample injection, collects and records a detector output at every data sampling pitch T1; and a second data collecting section which collects and records the detector output and a monitor output indicating an analysis-associated condition at every data sampling pitch T2 over a period from the start to the end of the chromatographic analysis, wherein the data sampling pitch T1 is shorter than the data sampling pitch T2. The second data collecting section further collects and records analysis history and/or optional comments; this is effective in verifying the validity of analysis results.
