Description
Drawell DW-W4 Optical Emission Spectrometers (Arc/Spark-OES) Economical and Easy Metal Analyzer
Product overview
DW-W4 Optical Emission Spectrometer is the most suitable instrument for the determination of various elements in different matrices (Fe, Cu, Al, Ni, Co, Mg, Ti, Zn, Pb, Sn, Ag, etc). It is an economical and easy solution for quick analysis near the furnace, metal material quality analysis, research laboratories, and metal grade identification.
The Drawell DW-W4 Optical Emission Spectrometers (Arc/Spark-OES) Economical and Easy Metal Analyzer supports research, pharmaceutical, environmental, food, industrial, and quality-control laboratories. Scientific China provides model selection, configuration review, export coordination, and formal quotations.
Key features
- Notes: The Buyer knows and agrees that the Seller may adjust the supply when the production of the above-mentioned instruments, spare parts and other suppliers change due to technological progress, product upgrading, market changes, etc.
- The instrument is calibrated with limited standard samples which Chongqing Drawell Instrument Co., Ltd. have for general purpose. For special alloy and special elements, the instrument must be calibrated by customer themselves. Or if customer is willing to provide sample collaboration for program development, the customer must provide accurate sample element content tables and ensure sample uniformity, but such curves are not used as acceptance indicators of the instrument.
- The DW-W4 optical emission spectrometer has a number of patented technologies that enable rapid determination of elements in metallic materials. The optical system uses a CMOS detector with a spectral range covering all typical materials. It is accurate and reliable for analysis from low-level elements to high-level elements. For different materials and different requirements, the cost-effective full-spectrum direct reading spectrometer can meet the requirements of metal manufacturing, processing industry and…
- 1. Optical system with superior performance
- The Paschen-Longge structure concave grating, full spectrum coverage, meets the customer’s need for full element detection.
- Direct optical technology and use optics made with MgF materials ensure optimum performance in the UV region.
- High resolution multi-CMOS readout system, lower dark current, better detection limit, higher stability, stronger sensitivity, meet N analysis requirements.
- 2. Large energy digital spark light source
- Fully digital intelligent composite light source DDD technology brings superior analytical performance.
- The compact design and semiconductor control technology make the light source more stable and more reliable.
- High-energy pre-combustion technology(HEPS), spark parameter adjustment, fully meet the excitation requirements of different substrates, different samples and different analytical elements.
- 3. Humanized sample spark stand design
- The spark stand directly introduces the spark light into the optical system
- Open sample stage for large sample testing requirements.
Applications
- Quantitative or qualitative laboratory analysis
- Research, method development, and routine quality control
- Application-specific testing with suitable accessories and methods
