ESCALAB QXi X-ray Photoelectron Spectrometer Microprobe
Meet your demands for increased analytical performance and flexibility with the Thermo Scientific™ ESCALAB™ QXi X-ray Photoelectron Spectrometer (XPS) Microprobe, which combines high spectral sensitivity and resolution with quantitative imaging and multi-technique capabilities.
The ESCALAB QXi XPS Microprobe is an expandable and optimized multi-technique instrument with unparalleled flexibility and configurability. It is extremely sensitive, producing high-quality spectra in seconds. System control, data acquisition, processing, and reporting are seamlessly integrated in the powerful Thermo Scientific Avantage Data System. The cutting-edge technology, driven by intuitive software, guarantees world-class results and productivity. The ESCALAB QXi XPS Microprobe, with its unique dual detector system, also delivers superb XPS imaging with excellent spatial resolution
Monochromated XPS
The twin-crystal, micro-focusing monochromator has a 500 mm Rowland circle, uses an Al anode (or a dual Al and Ag anode with the dual monochromator option), and allows you to select any sample spot size ranging from 200 µm to 900 µm.
Flood electron source
An electron source, co-axial with the analyzer input lens, is used for charge compensation when analyzing non-conducting samples with the monochromatic X-ray source, while a second flood source produces both low-energy ions to assist in providing effective charge compensation and low-energy electrons when the magnetic lens is not in use.
Lens and analyzer
The lens and analyzer system on the ESCALAB QXi XPS Microprobe is optimized for both spectroscopy and for parallel imaging; the single analyzer path means that the same instrument parameters (e.g., pass energy) can be used for both spectroscopy and imaging.
Detectors
The ESCALAB QXi XPS Microprobe is fitted with two detector systems: one optimized for spectroscopy, consisting of an array of six-channel electron multipliers, and one for parallel imaging, consisting of a pair of channel plates and a continuous position-sensitive detector.
Ion gun
The ESCALAB QXi XPS Microprobe has two options for rapid, high-resolution depth profiling: the standard EX06 ion gun, which is optimized for monatomic ion sputtering and ion scattering spectroscopy; and the optional monatomic and gas cluster ion source, MAGCIS, which is capable of monatomic ion profiling, cluster ion profiling, and ion scattering spectroscopy.
