Description
Enviroesca – chemical surface analysis under environmental conditions
The SPECS EnviroESCA is a novel and smart analysis tool, that overcomes the barriers of standard XPS systems by enabling analyses at pressures far above UHV. EnviroESCA is designed for high-throughput analysis and opens up new applications in the fields of medical technology, biotechnology and the life sciences. It offers the shortest loading-to-measurement time on samples of all types including liquids, tissue, plastics and foils, powders, soil, zeolites, rocks, minerals and ceramics.
EnviroESCA features a unique modular approach to the system design, combining the advantages of several specialized ESCA systems in a single entity. It is adaptable to suit different experimental conditions through the use of dedicated interchangeable sample environment modules. As in any conventional ESCA instrument the electron energy analyzer and the X-ray source are the key components of EnviroESCA. But combined with SPECS advanced, automated vacuum and gashandling systems, reliable working conditions in pressure ranges from ultra-high vacuum to hundreds of mbar are now possible. This combination enables the user to investigate even the most challenging samples of a class that was incompatible with traditional ESCA equipment. Furthermore the ionized gas atmosphere provides low energy ions and electrons, that lead to a selfcompensating process named environmental charge compensation. Thus nearly every insulating sample can be characterized without additional components
The unique sample environment in EnviroESCA makes it ideally suited for characterization of materials that may not be UHV compatible: The stringent UHV requirement of conventional XPS is dispensed with in EnviroESCA. Dedicated sample environment modules are provided as smart units for different classes of samples and applications. The modules are equipped with all relevant components such as sample stage, plasma cleaning and gas handling. Their exchange can be readily accomplished in just a few minutes.
