Procurement of 2051-254111020629 Shanghai Normal University X-ray Photoelectron Spectrometer(1)
| NO. | Product Name | Quantity | Main Technical Data | Remarks |
| 1 | X-ray photoelectron spectrometer | 1 | 1. Monochromatic Dual-Anode X-ray Source (Al anode and high-energy X-ray anode): Type: Water-cooled dual-anode with a single target surface, capable of replacing at least eight Al and four high-energy X-ray targets, with software-controlled target replacement and calibration. *Power: Accelerating voltage 15 kV, emission current adjustable from 0 to 25 mA (or greater) at any beam spot, achieving varying power levels, up to a maximum of no less than 375 W. At maximum power and maximum beam spot, the X-ray power per unit area must not exceed 0.4 mW/μm2 to prevent damage to organic polymer samples. 2. Electron Spectrometer Energy Analyzer: Type: 180° hemispherical sector analyzer; Average radius: *no less than 160 mm. 3. Charge Neutralizer: An ultra-low-energy single electron source coaxial with the electrostatic transmission lens, without dual-beam neutralization (electron and ion sources). 4. Single Ar ion energy: 0.5-5 keV; *Cluster Ar ion energy: 2-10 keV; Cluster Ar ion energy: 500-3,000 Ar 5. *Injection chamber sample control, observation, and adjustment: The chamber must be equipped with a horizontal multi-sample docking station capable of loading and storing three sample strips at a time, and must include software-controlled automated injection and sample exchange capabilities. | Bidding limit price: $623180 (US dollars) |
