Estimation of retention parameters for the interaction of analytes with a stationary phase in Gas Chromatography (GC).

The retention parameters are estimated from a set of temperature programmed GC runs. The GC simulation 'GasChromatographySimulator.jl' is used to compute the retention times with several sets of estimated retention parameters and compare these computed retention times with the measured retention times. An optimization process is used to minimize the difference between computed and measured retention times. The retention parameters resulting in this minimized difference are the final result. In addition it is also possible to estimate the column diameter d.


To install the package type:

julia> ] add RetentionParameterEstimator

To use the package type:

julia> using RetentionParameterEstimator


Please read the documentation page for more information.


In the folder notebooks notebooks, using Pluto.jl, for the estimation of retention parameters from temperature programmed GC measurements are available.

To use these notebooks Julia, v1.6 or above, must be installed and Pluto must be added:

julia> ]
(v1.7) pkg> add Pluto

To run Pluto, use the following commands:

julia> using Pluto

Pluto will open your browser. In the field Open from file the URL of a notebook or the path to a locally downloaded notebook can be insert and the notebook will open and load the necessary packages.
