Aaron McGaw eagerly anticipates his HPLC results.
High Pressure Liquid Chromatography (HPLC) is an important separation technique for compounds of low or no volatility thus it makes a nice complimentary procedure to GC. Like GC and all other chromatographic techniques, in HPLC the separation is based on a partitioning of the sample components on a stationary phase and a mobile phase. The liquid mobile phase is the variable. Both the polarity and pH of the mobile phase can be varied. We possess a Waters 510 HPLC equipped with a Waters 991 UV-VIS photodiode array detector. This equipment was obtained with the aid of a 1995 National Science Foundation Grant written by Dr. Franz.
