NanoFlow gas supply

The sample sprayer nebulizer gas supply pressure is electronically controlled
from 0 to 2 bar. The optimum pressure is sprayer-dependent, but usually lies
between 0.3 and 1.0 bar.

Purge gas

Purge gas typically flows at 100 L/h. It provides a positive pressure in the
source enclosure that reduces the chemical background interference caused by
contaminants in the laboratory air. You can adjust this flow via the Tune
window's Source tab, see the mass spectrometer's online Help for further
details.

Sprayer platform adjuster assembly

The sprayer platform adjuster assembly allows precise X-, Y-, and
Z-positioning of the sprayer tip. You can also withdraw the sprayer from the
source to allow access to the sprayer tip.
Using the two thumbscrews on the base of the adjuster assembly, you can
move the platform in and out of the source (see
platform adjuster assembly" on page
