H1099 - Online Sample Cleanup using columns switching and TrioVS
From LEAP
A setup of four valves (1 injection valve and 1 TrioVS 3-valve system) is used to accomplish solid phase sample extraction by one (1) pre-column followed by chromatography on two (2) analytical columns. The goal is an increase in throughput by simultaneously executing sample preparation tasks and one of the two gradient runs. Gradient runs themselves will not occur in a staggered fashion.
