Sentence examples for mobile phase system from inspiring English sources

In the later stage of HPLC development, widespread activities have been initiated in the design of phase systems and synthesis of highly selective stationary phases because of the fact that resolution in HPLC is much more dominated by the selectivity of the mobile phase system than by the column efficacy.

Binary isocratic mobile phase system was used for separation of VNT and IS.

However, the test mobile phase system had little influence on the retention time.
