- Wavelength range: 140-700mm
- Light chamber: constant temperature integrated light chamber, automatic constant temperature 35 ℃, accuracy ± 0.1 ℃.
Analysis Mode
The sample be quickly identified by pre-installed metal grades. You can freely choose the analysis mode, configure the analysis curve, and optimize the parameters according to the application requirements.
Vacuum System
- Vacuum degree: vacuum control is less than 2pa.
- Vacuum timing control, integral vacuum body patent, short working time.
- Vacuum pump; with anti-oil device to ensure that the light chamber is not polluted by oil.
- Intermittent vacuum control device: pump air for 3-5 mins, and can keep for > 5 hours.
Spark Excitation System
WL15A adopts full-frequency digital double-pulse excitation light source, variable frequency(200-800Hz) excitation technology, and double spark combined discharge to ensure the stability of the light source in the spark excitation system.
CCD Detector
Japanese Hamamatsu, research-level CCD, high sensitivity, wide linear range, good reproducibility, good stability and fast response.1 6-channel, high-precision CCD (CMOS optional), 3648px,total pixels > 50,000, high-resolution full-spectrum acquisition.
Excitation Platform
Excitation Light Source
Digital double pulse excitation light source, excitation frequency 200-800Hz；Dual-channel excitation device; the sample excitation adopts dual-channel and the data stability is higher; There are no resistive parts in the excitation circuit, no heat is generated during detection, and thermal stability is improved.
Open excitation platform
adaptable to larger sample analysis. The sample excitation adopts horizontal and vertical dual-gas path to make provoking more stable. Intelligent air pressure protection device for the excitation of argon gas make provoking safer.
