Functional Description

Divert/Inject Valve

Figure 6.
Divert/Inject Valve
The Rheodyne
switches between two positions: Load and Inject. The divert/inject valve is located on the front of
the TSQ mass spectrometer above the API source. See
divert/inject valve as a loop injector (for flow injection analysis) or as a divert valve. See
The divert valve enables switching the solvent front, gradient endpoint, or any portion of the LC
run to waste. TSQ Series Getting Started provides procedures for plumbing the valve in the loop
injector or divert valve configuration.
You can control the divert/inject valve from the data system. You specify the parameters of the
divert/inject valve on the Divert Valve page, accessible from the Instrument Setup window. For
instructions on operating the divert/inject valve from the data system, refer to the Help.
You can also use the divert/inject valve button to divert the LC flow between the mass spectrometer
and waste when the valve is in the divert valve configuration, or switch between load and inject
modes when the valve is in the loop injector configuration.
