Readily couples with all matrixes, resulting in long, steady signals and a uniform response throughout the periodic table - all while minimising fractionation
New Wave Research introduces the UP193 Solid-State, an all-solid-state 193nm laser ablation system designed specifically for ICP-MS solid-sampling analysis.
Featuring deep-UV absorption and short pulse-length performance, the system is said to readily couple with all matrixes, resulting in long, steady signals and a uniform response throughout the periodic table - all while minimising fractionation.
Applications include bulk and micro-feature analysis of metals; analysis of biological tissues, tree rings and gels; sulphate and sulphite analysis; and forensic analysis of plastics, ceramics, paint, glass and quartz.
The UP193 Solid-State is the latest addition to New Wave Research's Universal Platform series.
"The UP193 Solid-State is truly a flexible, fit-for-purpose laser-ablation system," said John Roy, vice president of New Wave Research.
"The system's high-absorbance, deep-UV wavelength enables total ablations on all materials, while its short pulse width prevents heating of the sample - a major contributor to fractionation.
"Users can now analyse all types of materials - opaque through highly transparent, conductive and non-conductive - without the need for other wavelengths.
"Moreover, the system's unmatched irradiance yields consistently smaller particles from all materials for maximum ionisation".
The UP193 Solid-State also features 13 pre-calibrated spot sizes ranging from 2um upwards; fluence and irradiance does not change with spot size says New Wave Research.
In addition, the system produces flat, uniform craters via a proprietary laser design and beam conditioning optics.
Further, the UP193 Solid-State incorporates an optical attenuator that adjusts the energy level for delicate through high-energy ablations without varying voltage or destabilising the laser.
This unique design generates more output from less input using the fewest components for higher reliability and a low cost of ownership.
The system is pumped by the same field-proven, dependable and stable laser used in the New Wave Research UP213 - said to be the most popular LA-ICP-MS system in the industry.
Compatible with all makes and models of ICP mass spectrometers, the UP193 Solid-State includes the same software platform found on all New Wave Research laser ablation systems.
This provides a wide variety of ablation functions such as depth profiling, sample mapping and auto-sampling.
