New ESI Instrument First to Support Sub-Cellular Elemental Imaging
Designed for Specific Research Applications, NWRimage™ System Offers Breakthrough Sub-micron Spatial Resolution, Fast Signal Response
Laser ablation (LA) systems such as NWRimage™ are used in conjunction with Inductively Coupled Plasma Mass Spectrometry (ICP-MS) systems to detect and analyze tiny amounts of material. As ICP-MS systems have become more sensitive, a need has emerged for LA imaging tools with < 1 micron spatial resolution - a capability not previously available on the market. Instead, researchers have had to use general-purpose LA systems that fail to provide the correct beam characteristics or signal response and lack long-term reliability.
To address these shortcomings, the NWRimage™ was designed from the ground-up specifically as an advanced elemental imaging solution. It uses a proprietary laser beam delivery system to yield sub-micron spatial resolution providing analysts with the tools they need to distinguish features at the sub-cellular level. It incorporates an ESI-manufactured Diode Pumped Solid State laser source for unmatched long-term stability and reliability over the course of millions of laser shots.
"The NWRimage™ is an outstanding example of the level of advanced
engineering capability ESI has on tap in order to help solve some of our
customers' most difficult challenges," said
In addition to its spatial resolution, the speed of the signal response is vitally important since it directly determines the available sample throughput or analysis time. The NWRimage™ is provided with a carefully designed aerosol path from point of ablation to injection into the ICP itself. This aerosol path combined with a novel Dual Concentric Injector (DCi) ICP torch, yields < 50ms signal response to accelerate the speed of analysis and enabling enhanced sample throughput.
Initial NWRimage™ units have been delivered to BAM (Bundesanstalt für
Materialforschung und -prüfung) in
"For this application we needed increased sensitivity and significantly
shortened analysis time for extended thin sections of tissues or biopsy
samples," said Dr.
ESI is taking advance orders for the NWRimage™ system for delivery in the Fall of 2015. To learn more or to participate in a trial, see us at www.esi.com/Products/AskAnExpert.aspx?=NWRimage or contact your local ESI representative.
