*Thesis Abstract:*

*High Performance Liquid Chromatography (HPLC) systems are valuable to
various laboratories around the world for their ease of use, speed, and
high resolution in separating components of non-volatile complex mixtures.
HPLCs however have special components and high prices. The high cost of an
HPLC poses a problem to many academic institutions required to train
students with a limited budget.*

*A Medium Pressure Liquid Chromatography (MPLC) system is presented as a
low-cost alternative for the HPLC for use in training in the academic
setting. The system built uses components and materials easily sourced in
the Philippines. The instrument designed is isothermal and isocratic. Its
detector is a simplified spectrometer assembled using basic circuit
components and an Arduino compatible microcontroller board. The detector is
capable of in-line data acquisition as well as stand-alone runs. A
cross-platform graphic user interface was also built using Processing
software to display and save resulting data. The produced prototype system
costs less than Php100,000.*
