Single Beam 185nm-910nm Atomic Absorption Flame AAS Instrument
Feature
1.Total reflection optical system, monochromator Auto wavelength scan and position.
2. Equipped with d2 lamp correction and self-absorption correction functions.
3. Unique designed titanium atomizer. Smooth combustion and fast thermal balance.
4. Auto-adjust negative power supply, HCL current and position to maximum the energy. Leak detection and auto switch off.
5. Eight slot HCL bases, auto select and auto Optimize the HCL position. One HCL works while other two warm up.
6. User could set the temperature raising curve for the graphite oven freely. Advanced graphite oven power controlled temperature setting. The temperature in the graphite tube is consistent to ensure the analysis accuracy.
