About / Help

Chroma to Gogh 0.3.0 — the art of chromatogram overlays.

Chromatogram Overlay, Analysis & Figure Export 2Go.

Chroma to Gogh is a client-side chromatogram overlay and analysis tool.

Drop one or more UNICORN 3.10 .res files (or supported exported CSV/TXT/TSV/ASC tables) directly onto the Runs list, select the runs you want, then choose Load selected.

All parsing and analysis run locally in this browser tab. Your chromatogram files are not uploaded to the web server.

Use renamed legend names, selectable injection alignment, UV autozero/normalization, peak analysis, comparison/CSV export, annotations, X zoom, and SVG/PNG/JPEG export as needed.

Move over the plot to read coordinates. Click to pin values from all visible traces.

Peak analysis

Choose “Select peak range”, then drag across a peak. Statistics use a linear baseline between the selected endpoints.

Trace	Run	Peak V [ml]	ΔV vs ref [ml]	Height	Area	FWHM [ml]
No peak range selected.

Peak comparison

Add one or more analysed peak ranges. Each range uses its first visible UV trace as the ΔV reference.

Peak	Range [ml]	Trace	Run	Inj	Peak V [ml]	ΔV [ml]	Height	Area	FWHM [ml]
No peak ranges added yet.

Loaded run styles
