A high-pressure liquid chromatography method based on
reported literature was developed for the quantitative
analysis of chlorpheniramine, pseudoephedrine,
phenylpropanolamine and acetaminophen in dissolution
fluids and urine. The effects of buffer, pH and different
concentrations of organic solvent in the mobile phase on
chromatographic separation are described in Chapter I.

In designing a solubility based separation process
for solvent recovery of an organosolv pulping process, the
phase behavior of polymeric lignin molecules in alcohol -
water mixed solvent should be known. In this study,
sodium lignin sulfonates (NaLS) samples were fractionated
into three different molecular weight fractions using a
partial...
