The PHI Quantes Equipped with Dual Scanning Monochromatic X-ray Source
The PHI Quantes is equipped with a dual scanning X-ray source composed of a hard X-ray source (Cr Kα) and a conventional soft X-ray source (Al Kα), which have different energy values. This state-of-the-art XPS instrument has a capability to analyze the very small area where the user is interested in and a large area of the uniform sample surface.

What is Parallel Imaging MS/MS Option ?
The parallel imaging MS/MS option available for TOF-SIMS achieves high-speed and high- sensitive tandem mass spectrometry of the outermost surface of a material, thereby enabling high-speed measurement of both MS1 and MS2 at the same time under static-SIMS conditions.

What is Hard X-ray Photoelectron Spectroscopy?
The basic principle of hard x-ray photoelectron spectroscopy is similar to that of general XPS, which irradiates excitation light on the sample surface and measures the kinetic energy of the photoelectrons emitted. While the photon energy of the monochromatic AlKα x-ray source most commonly used in traditional XPS instruments is 1486.6 eV, the photon energy of the excitation source used in hard x-ray photoelectron spectroscopy is 5 to 8 keV, more than triple.
