HPLC is widely used for the analysis of constituents of a pharmaceutical actives, drug products, pesticides, and countless other substances. In UPLC, or ultra-high performance liquid chromatography, column particle size of less than 2um can be used. This allows for better separation than the typical particle size of 5um that are used in HPLC.

Drug release was performed by a high performance liquid chromatography (HPLC). Stably coated gelatin and poly(L-lactide- co-epsilon-caprolactone) (PLCL) nanofibers were observed by SEM.
Samples were then dissolved in HPLC-grade tetrahydrofuran (THF), filtered through 0.2 μm filter, and loaded into vials with a septum for GPC. Molecular weight was measured by GPC (THF, 20°C, 1.0 mL/min) against polystyrene standards on a Hewlett-Packard instrument (series HPLC) equipped with Polymer Laboratories 5 μm mixed-C columns and
