The cost of purchasing a one-piece torch is slightly lower. It is cleaned as a whole, mak-
ing disassembly and subsequent assembly unnecessary. On the other hand, this torch
has to be completely replaced when worn.

The PlasmaQuant PQ 9000 includes a special V Shuttle Torch design. The up-right ar-
rangement of the torch reduces clogging and soot formation.
The torch is mounted with the holder (shuttle) onto the rail guide. Doing so automati-
cally connects the internal gas inlets for the plasma and auxiliary gas. The torch is then
moved by hand along the rail guide to the plasma compartment where it locks in the ad-
justed operating position.

The analyte emission in plasma is observed from two directions, axial and radial
(DualView PLUS). The emission radiation is selectively coupled via the transfer optics
from one of the two directions to the monochromator. The working range is increased
by attenuating both directions of observation.
A double monochromator comprising of a prism and an echelle grating is used for spec-
tral analysis. A grating with high blaze angle (76°) achieves the high spectral resolution
of 0.002 nm at 200 nm of the PlasmaQuant PQ 9000 Elite (High-Resolution Optics).
The PlasmaQuant PQ 9000 has a spectral resolution of 0.006 nm at 200 nm.
