Description

Digitize and analyze chromatography peaks directly from your browser. Calculate Area, Height, and Efficiency (N). ChromOverlay is the essential utility for analytical chemists who review literature, legacy reports, or vendor applications. It allows you to obtain quantitative data from static images of chromatograms. How it works: 1. Calibrate: Draw a box around the graph to define the Time and Intensity axes. 2. Trace: Use the highlighter to digitize the peak or use the "Quick Triangle" tool for an instant estimate. 3. Analyze: The tool calculates Area, Height, and Efficiency (N). 4. Export: Save your results to CSV. Includes advanced features like manual apex correction and adjustable baselines for precise integration. Works locally—no data leaves your browser.
