Thermo Fisher Scientific Inc., the world leader in serving science, will demonstrate its recently announced Thermo Scientific Niton XL3t Series with geometrically optimized large area drift detector (GOLDD) technology at the ISRI 2009 Convention and Exposition, April 27-29, Mandalay Bay Convention Center, Las Vegas, Nevada, Booth #732. Thermo Fisher Scientific is the world’s leading manufacturer of handheld x-ray fluorescence (XRF) analyzers.

Groundbreaking GOLDD technology delivers improvements in light element detection, overall sensitivity and measurement times – as much as 10 times faster than conventional Si-PIN detectors, and up to 3 times more precise than conventional smaller, silicon drift detectors.

Thermo Fisher was able to surpass the performance of conventional Si-PIN and SDD detectors by combining the award-winning Niton® XL3t’s 50kV, 2-watt x-ray tube, closely optimized geometry and patented signal processing hardware and software with our proprietary large area drift detector. The end result is GOLDD technology, delivering superior performance in the form of faster analysis, lower detection limits and unparalleled analytical precision. Further, this innovation allows analysis of light elements such as magnesium (Mg), aluminum (Al), silicon (Si), phosphorus (P) and sulfur (S) without helium or vacuum purging.
