Product Description

ATOMIC ABSORPTION SPECTROPHOTOMETER DW-180B

FEATURES

1. The core optical platform of the instrument adopts an integral casting structure, with a thickness of 20mm cast aluminum molding and a suspended platform design. The deformation of the casting under high/low temperature thermal effects is within 0.2mm, so the stability is comprehensively improved.
2. Aiming at the requirements of multi-element detection tasks, the uniquely designed 8-light position lamp holder is compatible with the light position element memory function of conventional lights, and easily supports 1~4 lights to be preheated at the same time, so that the light source of the instrument is on standby at any time. Ease of use further enhancement
3. The flame-fog chamber system adapts polyphenylene sulfide, the internal material of the aero-engine, and the overall molding design, which has good material properties such as good flame retardancy, corrosion resistance, high temperature resistance, and high strength, ensuring long-term service life.
4. The industrial TA2 grade high-purity titanium integral casting flame combustion head has excellent corrosion resistance, and the seam surface finish is quasi-mirror by using the slow wire-moving process. At the same time, it supports the expansion of various wide-slit combustion heads, and the analysis of high-salt samples is more convenient.
5. A new generation of flame control system: continuously adjustable and reliable gas circuit control, real-time status breathing light and other designs, equipped with active/passive dual safety interlocking and protection, automatic ignition, and other functions, so that the instrument can work safely and stably in complex environments.
6. The new oxygen-enriched flame technology can be upgraded, and the flame temperature rises to above 2700°C, realizing a high-temperature flame without dangerous chemical laughing gas, and ensuring the determination of high-temperature elements Ca, Al, Ba, Mo, Ti, V, etc.                 Parameters
