HPLC-UV data of two chemical mixtures
Two chemical mixtures of three compounds have been measured using HPLC-UV. Two of the compounds are known: diazinon and parthion-ethyl, both organophosphorus pesticides. Each data matrix consists of 73 wavelengths and 40 time points. The challenge is to infer the pure spectra of the individual compounds, as well as their time profiles.
A list of four elements. The first two,
are the mixture matrices of the two analytes and one unknown
interferent. The last two,
sp2, contain the pure
spectra of the two analytes.
