ICP7800 Inductively Coupled Plasma Optical Emission Spectrometer

【Application】

The ICP7800 is a full-spectrum direct-reading inductively coupled plasma optical emission spectrometer with outstanding anti-interference and analytical detection capabilities. It is used in high-end analysis requirements for research and testing, enabling easy qualitative, semi-quantitative, and precise quantitative analysis. It is an ideal instrument for simultaneous analysis of constant, trace, and ultra-trace inorganic elements.

【Specification】

² Plasma RF Source:

· Low Power Mode: Provides 400W ultra-low power standby with a small flow torch, argon gas consumption ≤5L/min during standby.

· Plasma Observation Modes: Configurable for axial, radial, and dual-observation modes. The vertical torch adapter is resistant to high salt in radial observation mode. In axial observation mode, an air compressor is required to use an air knife to remove the tail flame. The plasma observation position for dual-observation mode is adjustable, offering interference resistance for different elements.

² Sample Application System:

· Quartz Torch: Removable three concentric tubes, the outer tube with a diameter of 22mm and the inner tube with a diameter of 18mm, with a central tube inner diameter of 2mm, resistant to hydrofluoric acid.

· Nebulizer: Universal high-salt resistant nebulizer with an outer diameter of 6.2mm.

· Spray Chamber: Double-tube/tangential spray chamber, resistant to hydrofluoric acid.

· Gas Control: Plasma gas, auxiliary gas, and carrier gas controlled by mass flow controllers (MFCs).

² Optical System:

· Optical Chamber: Precisely temperature-controlled at 35°C±0.1°C, with a vacuum system.

· Wavelength Range: 160nm to 900nm, with independent dual optical paths and dual gratings.

· Optical Resolution: 0.006nm@200nm, 0.012nm@400nm, 0.019nm@600nm.

² Detector:

· Photoelectric Conversion Detection Unit.

· Intelligent Integration with Signal and Background Synchronization Acquisition.

Software: Supports Chinese/English/Russian, compliant with 3Q c
