M|Chroma

An open-source software for the analysis of chromatograms.

Getting Started

Installation

Either clone the repository or download the .zip file and extract.

Requirements

You will need to install Python >=3.8.0 to use this software. MChroma is not compatible with Python 3.7, which does not support an extended Unicode charset. M|Chroma is developed with Python 3.8.8, so that is the safest version to use. Download Python 3.8.8 from: https://www.python.org/downloads/.

Once Python is installed, run requirements.py to install the required packages.

Running the Program

Start the software by running mchroma.py. Tutorial coming soon!

Current Features

Implemented Features

Peak picking (from bounding points or from single point in peak)
Automatic calculation of retention time, theoretical plate count, peak width peak area, and more
Baseline correction
Peak summary table exporting to .csv file
Signal scaling

Unimplemented/In-development Features

For a more detailed description of planned features, check out agenda.txt.

Modified area calculations (base-valley, valley-base, and valley-valley)
Time scale shifting/peak referencing
Normalization
Automatic peak picking by threshold

Challenges, Bugs, and Other Complications

Currently, this program only supports .asc files exported from Shimadzu CLASS-VP analysis software.
Peak summary table is cut off. This can be manually fixed to some extent by adjusting the "bottom" parameter in the "Configure subplots" context of the plot menu.
Edit>Undo/Redo feature is very buggy
