Tosoh Chromatocorder 21 Chromatogram Data Processor for HPLC (Used)

From the baseline, you can verify whether the state of the system—such as the solvent, pump, column, and detector—is normal by checking for pump pulsation, detector noise, drift, and so on.
The presence of minute peaks or small shoulders that are often overlooked is also important.
You can confirm the status of the column by the peak shape and separation state. These subtle changes can only be captured by a pen recorder.

A chromatogram drawn by a pen recorder. Originally, a wealth of insightful information should have been extracted from these chromatograms.
Recent chromatogram data processors, driven by manufacturers (perhaps due to the forced use of character-based dot matrix printers), seem to favor techniques like chromatogram processing over the importance of faithfully recording the chromatogram itself.
The SIC Chromatocorder 21 inherits the advantages of the pen recorder while incorporating excellent integration and report generation functions.
