Leeman Labs Said the following about this unit;
"DRE (direct reading echelle) is over three times faster than traditional sequential ICP's which means greater throughput, less sample and argon consumption, less waste disposal, and lower analytical cost-per-sample.
Because of the DRE design you always analyze the correct spectral line just like a simultaneous ICP system.
The DRE uses simple to operate macro-driven software that automates routine calibrations, runs control samples and lets you know if a sample is out of spec -- leaving you more time for other tasks at a hand."

My impression is that the Echelle optics disperse the spectrum produced in the plasma source, widely separating the wave-lengths and thereby minimizing interference and the need for inter-element corrections.
This process also improves resolution without a reduction in light intensity and thus increases sensitivity. The software/hardware combination in this unit permits you to move the detector "on peak" to a chosen wavelength when detecting a target analyte, similar to SIM scanning in a mass spectrometer.
This improves resolution and detection limits to superior levels.
An axial view of the plasma for the detector also enhances detection limits. Axial view imits are typically ten times better than for radial systems alone.
This unit, has a dual view system which combines the axial and radial views thereby permitting ultra-trace, trace, and major element detection without the need for multiple sample dilutions.
