Both UHPLC and UPLC enable scientists to grapple with smaller particles more quickly than was previously possible, however, key differences exist between the two systems shows the comparison of UPLC and UHPLC for the separation of some common small molecule drugs. The UPLC separation results in about a 54% increase in peak capacity over the UHPLC separation. In addition, the UPLC separation appears to have 3- to 4-fold higher signal intensity. The reasons for these differences in performance are numerous UHPLC, while powerful, is far less forgiving than HPLC in this regard. Beside robustness, capital cost and operating cost for HPLC are lower. Instrument cost for HPLC are approximately 20% lower than the UHPLC. The reduced operating cost include utilizing HPLC grade solvents instead of higher cost UHPLC or LCMS grade solvents

UHPLC is presently defined as the use of sub-2 μm particles with a low dispersion HPLC system, optionally with a pump capable of > 600 bars pressure. UHPLC is still HPLC. Nothing changed except it implies you will use sub 2-micron particles in the column (in other words, just the particle size is highlighted) UPLC vs HPLC. UPLC, or UHPLC (Ultra High Performance Liquid Chromatography) and HPLC are both liquid chromatography techniques to separate the components of a compound or mixture. The table below highlights some of the differences between these two separation techniques The technique used is HPLC. LC is NOT HPLC. LC is a very generic term for liquid chromatography. UHPLC and UPLC were developed as marketing terms only Can I improve lab efficiency by purchasing modern columns, but using them on older HPLC equipment? Will using smaller particle columns on older systems get u.. High performance liquid chromatography (HPLC) and ultra-high-performance liquid chromatography (UHPLC) are two types of commonly used separation methods using liquid chromatography.
