Morphology
The meaning 'a method of chromatography using paper as the medium' is directly and compositionally derivable from 'paper' (the support material) + 'chromatography' (a separation technique). This is a literal, productive noun-noun compound and is cross-linguistically regular, so a B1 learner who knows both constituents would readily understand it.
Etymology
Paper chromatography comes from a simple lab trick: a strip of paper is touched with a liquid that moves up and carries different colors at different speeds, and chromatography means 'separating by movement'. So, paper chromatography is a 'method to separate parts of a mixture' by letting them travel along paper.
