Leeman Labs DRE
Inductively Coupled Plasma-Optical Emission Spectrometer
This photo shows the Leeman
Labs DRE ICP-OES system. Why after all these years with ICPMS would
WCAS buy an ICPOES? Because someone finally made an ICPOES which really
minimizes interferences. A LEEMAN LABS Direct Reading Echelle ICPOES, or DRE instrument has been added to the arsenal at WCAS. Designed to
handle sub-ppm to percent level metal concentrations, this new instrument will help provide accuracy, sensitivity and productivity.
At the heart of the DRE is the 2 dimensional, high resolution Echelle
grating. With a 2-dimensional dispersion the spectrum produced is dispersed not only by wavelength but also by order. This results in the
ability to quickly, precisely and reliably locate any peak in the ICP spectrum. This is especially critical when the signal to be measured is
close to the background level (or detection limit). The patented Precise Wavelength Selection System utilizes the dispersion of the 2-dimensional grating/optical system to lock ON-PEAK thereby nearly
eliminating inter-element interferences and the associated inaccuracies. Combined with a signal detection system based on time proven PMT’s
having the widest dynamic range of response, greatest sensitivity, and fastest measurement times, the DRE from LEEMAN LABS will be a
welcome addition.
WCAS has added this new instrument to the inorganics group to
compliment the several ICPMS systems and GFAA already on-line. The ability to handle
sample matrices with percent level analytes without having to dilute the sample a million-fold for ICPMS testing will improve the
measurements and reduce ICPMS downtime.
