Sample Introduction System:
Includes a 12-roller 3-channel, computer-controlled peristaltic pump with automatically adjustable speed 0-125 rpm. The ICP-5000 is supplied with a standard glass concentric nebulizer and a glass cyclonic spray chamber, while HF-resistant nebulizer and spray chamber are supplied for high HF/salt content analytes.ICP System:
The ICP system comprises of a free-running solid- state RF generator, a load coil, a demountable quartz torch and automatically controlled gas flow. The RF generator is continuously adjustable from 750 to 1350 watts (Dual), maximum up to 1600 watts (Radial). The coupling efficiency is greater than 80% with ≤ 0.1% variation in output power stability and ≤0.01% variation in output frequency stability. The RF generator produces an oscillating electromagnetic field at a frequency of 27.12 MHz. This radiation is directed to the load coil through which delivered to the torch. The argon gas flowing through the torch will form a plasma in the RF field. Plasma argon, auxiliary argon and nebulizer argon are regulated in a fully integrated gas flow and automatically controlled by MFC in 0.01 ml/min increments.Spectrometer
Polychromator : 2D Echelle Grating, 52.91 lines per mm and a blaze angle of 63.4 degrees. Thermostatted optics: The entire optical system is encapsulated in a thermostatted enclosure 36℃±0.5℃ and purged with argon or nitrogen gas (UV region). Recalibration: Spectra of Carbon, Nitrogen and argon elements are used for automatic wavelength calibration during ever y ignition of the plasma. Do not require either calibration solution or mercury /neon lamp that is free from calibration consumables or preheating of the lamp.Detector:
The ICP-5000 features a megapixel Cryogenic area-array Charge-coupled Device (CCD) detector with unique back-illuminated technique results in average quantum efficiency greater than 75% in UV region. Three-level Thermo Electric Coolers (TEC) are equipped that can drive the cryogenic temperature down to -45℃, cooling time 3 min. Anti-blooming of the detector is functioned in pixel level.Software:
Qualitative, Semi-quantitative and quantitative analysis using full spectrum acquisition of all the detected elements and enhanced with a powerful SQL Server database ensuring integrity of raw data and traceability of operations. A spectra base of over 50,000 lines, out of each line at least 30 pixels can be selected for detection. Multi-method interference correction includes standard comparison method, internal standard method, interference element correlation (IEC) and standard additions. Instrument calibration supporting plasma torch collimation, light source optimizing, etc. Operation procedure & status can be visually supervised in real time through a dynamic simulation display. Integrated functions for the operation of autosampler.Plasma Viewing:
In a dual view type of ICP-5000, viewing of the plasma is accomplished by computer control of a mirror located in the optical path and allows selection of axial, radial or mixed viewing modes and adjustment of the plasma viewing in both the vertical and horizontal planes.
