Which ICP-OES Optical Technology Offers Superior Performance: Echelle or ORCA?
Schematic of a typical echelle system
Plasma, radial view
ORCA captures the entire spectrum
ORCA-based systems display a constant resolution over a wide wavelength range
The heart of any ICP-OES instrument is the optical system. So it’s important
that scientists, lab managers, and other users understand some salient facts
about a very critical component of these instruments. This knowledge will help
users choose the best spectrometer for their laboratory.
This paper explains the fundamental differences between the two leading optical
designs and discusses how each technology deals with technical challenges such
as light loss, stray light, spectral order overlaps, and others.
The paper also explains how each can potentially affect the outcome of various
analyses. Application examples and analytical results are included.
