The full-spectrum direct-reading inductively coupled plasma optical emission spectrometer (ICP-OES) has outstanding anti-interference and analytical detection performance. It is used in high-end analysis needs such as R&D and testing, and can conveniently perform qualitative, semi-quantitative and precise quantitative analysis. It is an ideal instrument for simultaneous analysis of major, minor and trace inorganic elements.
Excellent analysis performance: enables fast and precise element analysis, covering simultaneous analysis of inorganic elements from major to trace levels, with a high dynamic range and outstanding stability.
Advanced RF power technology: adopts a fully digitally controlled dual power supply design with a wide power adjustment range (500 W-1600 W) and supports a low-power standby mode, reducing argon consumption and adapting to the analysis requirements of a variety of complex samples.
Multi-functional observation modes: provides four observation modes: axial, radial, bidirectional and simultaneous bidirectional; the intelligent attenuation function makes direct analysis of high-concentration samples possible without repeated sample dilution, simplifying the pretreatment process.
Leading optical system design: equipped with a thermostatic three-dimensional optical system and an echelle grating, with a wide wavelength coverage (165-900 nm) and high resolution, ensuring long-term stability and accuracy.
User-friendly software interface: has an intuitive graphical operation interface that is easy to use, supports remote diagnostic services, complies with electronic signature management regulations, and facilitates the generation of test reports and data management.
Optimized sample introduction system: precisely controls multi-channel gas flow through mass flow controllers; a variety of sample introduction systems (such as high-salt-resistant or HF-resistant) are optional, able to cope with various complex sample conditions and ensuring injection precision and stability.
| Voltage | 220 V AC ±10% |
| Room temperature | Ambient temperature (10-30) ℃ |
| Relative humidity | (20-80)% RH |
| Plasma RF source | Fully digitally controlled dual power supply RF design, wider power range 500-1600 W, adjustable power, with stronger sample adaptability. |
| RF generator | Self-excited RF generator: fast power matching, strong power load capacity, able to directly analyze 100% toluene samples; automatic tuning; water-cooled heat dissipation; adapts to power switching for complex sample analysis; no moving parts; shock-resistant, interference-resistant and more reliable. |
| Low-power mode | LOW mode: provides 500 W ultra-low power standby, reducing argon consumption by more than 50%; argon consumption in standby ≤5 L/min. |
| Plasma observation | Configurable in four observation modes: axial, radial, bidirectional and simultaneous bidirectional. The vertical torch avoids high-salt deposition. Axial observation uses a metal cold cone to remove the tail flame for higher sensitivity. The radial observation plasma position is adjustable, with stronger anti-interference capability. |
| Intelligent attenuation | With axial and radial attenuation functions, able to attenuate samples within 100-fold concentration, so that high-content elements in a sample can be analyzed in a single run without repeated dilution, reducing sample pretreatment difficulty and supporting simplified analysis. |
| RF frequency | 27.12 MHz, coupling efficiency greater than 80%. |
| RF power / frequency stability | RF power stability ≤0.1%; RF frequency stability ≤0.01%. |
| Optical system | Thermostatic three-dimensional optical system with few reflections and low light energy loss. All optical elements are sealed in a thermally balanced light chamber; the main unit and light chamber are thermally isolated, better resisting external ambient temperature changes. Light chamber: precisely thermostatically controlled at 36 ℃ ±0.1 ℃, argon purging. |
| Grating spectroscopy | Stable and efficient fully fixed echelle grating spectroscopy system, no moving parts, strong shock resistance, stable and reliable. |
| Wavelength range | 165-900 nm, full-wavelength coverage. |
| Monochromator | Focal length 400 mm, all-reflective imaging optical path, quartz prism two-dimensional dispersion system. |
| Grating type | Echelle grating: 53.6 L/mm, 63.5° blaze; the more lines, the higher the resolution. |
| Spectral calibration | Full-spectrum real-time calibration technology (TARC): uses interference-free neon characteristic lines for real-time correction of slight spectral shifts, achieving optimal spectral integration, ensuring long-term stability and effectively eliminating the influence of spectral drift on measurement. |
| Purged light chamber | For the determination of wavelengths below 189 nm, argon is selected for optical path purging; no vacuum pump is required, avoiding vacuum oil backflow and contamination of the light chamber. |
| Optical resolution (FWHM) | ≤7 pm @ 200 nm (resolution and detection limit must be obtained under the same conditions). |
| Extendable deep-ultraviolet Cl/Br analysis | Dual-grating design brings the lower limit of spectral analysis down to the 130 nm deep-ultraviolet region. |
| Detector | Pixel-level cooled proprietary large-format ECCD detector. |
| Detection unit | 1024×1024-pixel large-format CCD detector, single exposure. |
| Imaging size | 25.4 mm × 25.4 mm large-format photosensitive unit, using 24×24 µm large pixels, delivering high-sensitivity response, with a large overall frame area enabling a wider spectral range at high resolution. |
| Pixel-level cooling | TEC cooling encapsulated inside the sensor, acting directly on the pixels, with a cooling temperature greater than -10 ℃, effectively preventing condensation on the CCD surface with no gas purging protection required. |
| Anti-saturation overflow | Back-illuminated anti-overflow protection design for each pixel, completely eliminating the spectral-line saturation overflow problem, with no need to worry about the influence of spectral-line saturation on adjacent lines. |
| Intelligent integration | Synchronous signal-background acquisition, with exposure time depending on the light intensity of the spectral line, automatically calculating the optimal exposure time, obtaining both high-intensity and weak signals at the best signal-to-noise ratio, broadening the dynamic range so that high- and low-content elements can be detected simultaneously, avoiding repeated sample dilution. |
| Detector surface | No light-conversion chemical coating on the detector surface, so detector replacement due to coating aging will not occur. |
| Sample introduction system | Standard quartz concentric nebulizer, quartz cyclone spray chamber, detachable torch. |
| Peristaltic pump | 12-roller, 4-channel peristaltic pump, pump speed 0-125 rpm continuously and automatically adjustable. While ensuring stable sample introduction, it supports simultaneous operation of the sample tube, internal standard tube, waste liquid tube and auxiliary reagent tube (hydride generator), facilitating the analysis of complex samples. |
| Gas path control | Precisely controls multi-channel gas flow through mass flow controllers, controlling up to five channels, including nebulizer gas, auxiliary gas, cooling gas and expandable additional gases (O₂ and Ar), with an accuracy of 0.01 L/min. |
| Software | Graphical operation interface, convenient and intuitive, with qualitative, semi-quantitative and quantitative analysis functions; a classification- and version-based method library management software facilitating method management, maintenance and inheritance, with some standard methods built in to help improve analysis efficiency. |
| Analysis speed | Approx. 200 spectral lines per minute. |
| Sample consumption | Only 2 mL required. |
| Preheating time | From standby to plasma ignition less than 5 minutes. |
| Automation interfaces | Can be coupled with an automated sample digestion workstation (the digestion system uses a graphite digestion electric heating mode, realizing automated digestion, constant volume and injection, supporting simultaneous processing of 48 or more samples); an organic sample direct injection analysis system interface (with sample refrigeration, temperature below -15 ℃); an online digestion module interface; an online hydride generation analysis system interface; can be connected to an ion exchange workstation for speciation analysis or low-concentration enrichment and high-matrix removal analysis; can be connected to an autosampler (240 or more sample positions configurable). |
