Pyroxene Group - an overview | ScienceDirect Topics

The principal members of pyroxene and amphibole groups are listed in Table 4. Three series of pyroxenes – the enstatite-hypersthene, diopside-jadeite, and augite series – occur in igneous rocks. In nature, pyroxenes are often mixtures. Among the three series of pyroxenes, the augite series is geochemically more important than the others.

Factors Affecting Resolution in HPLC - Sigma-Aldrich

USP tailing factor T. A tailing peak has a front of greater than 1.0, while a fronting peak has a front of less than 1.0. The U.S. Pharmacopeia (USP) has also recommended measuring tailing factor (T) as the back-to-front ratio of a bisected peak measured at 5% of height. The ratio is made by dividing the total width by twice the front width.
