Product Overview
The MIC Full Spectrum Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) is an upgraded, premium-tier analytical instrument engineered for the most demanding elemental analysis. Designed to deliver exceptional sensitivity, massive throughput, and robust long-term stability, the MIC is ideal for research and routine analysis across environmental, metallurgical, chemical, and food safety laboratories.
By integrating a multi-million-pixel CCD detector with a rigorously (constant temperature) Echelle optical system, the MIC ensures that every photon is captured with maximum fidelity and minimal noise.
Core Advantages & Design Features
1. Advanced 3-Million Pixel CCD Detector
The heart of the MIC is its high-efficiency, solid-state CCD detector featuring over 3,000,000 detection units. With a rapid reading speed of ≥2MHz and continuous pixels across the wavelength range, it allows arbitrary wavelength selection. The inherent anti-blooming design prevents signal overflow from intense emission lines, ensuring accurate measurement of both trace and major elements simultaneously.
2. Ultra-Fast 3-Stage Thermoelectric Cooling
To achieve the absolute lowest detector dark current and maximize signal-to-noise ratio, the CCD is equipped with a highly efficient 3-stage thermoelectric cooling system. It rapidly reaches an operating temperature of ≤-45℃ in under 3 minutes, ensuring pristine baseline stability right from startup.
3. Rigid, Constant-Temperature Optical System
Utilizing an Echelle grating and prism 2D dispersion system, the MIC achieves high optical energy throughput. To guarantee ultimate stability, all internal optical components (grating, prism) are fixed permanently in place—zero moving parts. The optical chamber is precision-thermostatted at 38℃ ± 0.1℃ and can be purged with Argon or Nitrogen (consuming <3L/min for <200nm lines), providing a rock-solid foundation for reproducible results.
4. Ultra-Wide Wavelength Range & Outstanding Resolution
Covering a massive 167nm to 1000nm full wavelength range, the MIC effortlessly handles the most challenging spectral lines. It delivers exceptional optical resolution (FWHM):
- As 189.042nm: < 0.007nm
- Ca 393.366nm: < 0.017nm
- Ba 614.172nm: < 0.024nm
- K 766.490nm: < 0.035nm
5. High-Performance RF Generator & Plasma
Powered by a solid-state RF generator at 27.12MHz with output power ≥1300W. The plasma coil features a PTFE protective layer for superior corrosion resistance and zero-maintenance operation. The vertical torch placement ensures optimized plasma viewing.
6. Incredible Analysis Speed & Efficiency
Capable of analyzing ≥50 elements or spectral lines per minute, with each line integrating for ≥10 seconds. Remarkably, it consumes <2ml of sample to measure over 70 elements, making it highly efficient for precious or limited-volume samples.
7. Superior Analytical Precision & Stability
- Wide Linear Dynamic Range: ≥10^6 (verified with Mn 257.6nm, correlation coefficient ≥0.9996).
- Precision: RSD ≤ 0.5% for 10 repeated measurements of 1ppm/10ppm multi-element standards.
- Long-term Stability: RSD < 1.0% over a continuous 4-hour test without internal standard correction.
- Simultaneous Internal Standardization: Internal standards and measured elements are exposed simultaneously, ensuring real-time matrix correction.
