Second generation CCD-based spectrometer is newly configured to permit ultimate accuracy in cobalt and titanium alloy analysis, plus cost effective and fast analysis of small steel and iron samples
Thermo Electron says its ARL Quantris is the first instrument of its type to achieve the performance of traditional photomultiplier tube instruments.
The state-of-the-art, second generation charge coupled device (CCD)-based spectrometer is newly configured to permit ultimate accuracy in cobalt and titanium alloy analysis, plus cost effective and fast analysis of small steel and iron samples.
Cobalt and titanium alloys are increasingly becoming the materials of choice for use in highly-stressed and heavy duty applications, such as nuclear power plants and food processing plants.
Thus their analysis requires the highest levels of accuracy in a high-pressured environment.
The ARL Quantris's simple architecture allows for high accuracy, stability and reliability especially in demanding applications.
The spectrometer can be configured with up to three spectrographs in order to cover wavelengths from 130 to 780nm, enabling the analysis of all major elements in alloys and resulting in major savings on alloying elements.
The ARL Quantris features Thermo Electron's patented current controlled source (CCS).
This is the first time that such a high performance source is available on a CCD based instrument, says the company, offering significant advantages over other spark generators currently used for OES.
The CCS enables the simplification of small-sample preparation for example small samples of iron and steel, affording fast analysis times and consequently, drastic reductions in analysis costs.
Using a dedicated sample table, sample adaptors and a specific sparking condition, Thermo Electron says the spectrometer can quantitatively determine up to 22 elements in small steel and iron samples in less than two minutes.
The ARL Quantris provides highly accurate analytical results while also featuring excellent stability and autonomy.
Drift corrections and instrument stand maintenance are required only once a week, thereby leading to lower operation costs.
Customers report that the analytical results achieved with the ARL Quantris exceed their expectations, says Thermo.
In addition, the company says no instruments have incurred any operational defaults since their installation, and many of them have already been in use for more than 18 months.
