From the comparison, the conclusion is drawn that water jacket method is better than direct expansion method.

A study of the application of high performance capillary electrophoresis and direct ultraviolet detection——The separation and determination of organic acids in fruits and vegetables;

5, 3, 6, 12, 24, 36, 48, 60, and 72 h after the oral administration to determine the plasma reboxetine concentrations by high-performance liquid chromatography with ultraviolet detection at 210 nm.

999 5) shows that ultraviolet detection as a simple and convenient method can be used to rapidly measure CLA content in the complexes.

Methods Captopril was stabilized by forming an adduct with p bromophenacyl bromide and this adduct in plasma was measured by high performance liquid chromatography with UV detection following a single oral dose 50 mg of captopril test and reference preparations respectively given to 18 healthy volunteers.

This paper introduced a new technique to measure the water resistance of sunscreens—in vitro technique.

To determine the phase difference of phase center and geometry center, we proposed a combination of indoor measurement and outdoor measurement, and described the principles, methods, procedures and features of these two measurement methods.
