Flame Atomic Absorption Spectrophotometer
Features
1. Highly automated functions to meet the needs of users best
2. Built-in optimal parameters for users to grasp quickly and easily
3. Wavelength automatic scanning, automatic peak finding, automatic switching of spectral bandwidth, automatic adjustment of negative high pressure, lamp current, etc., systematic setting or single setting, flexible operation
4. Acetylene gas leakage alarm, real-time flame monitoring, automatic flameout protection, automatic power-off protection in case of other abnormalities, to ensure the safety of operators and instruments
5. Excellent scalability, which can easily meet the diversification and complexity of analytical samples, and easily meet a variety of analytical needs
6,Using a transflective device, the energy of the sample beam and the background beam are automatically balanced when the background of the xenon lamp is buckled
7. Using the classic design of the atomizer and the all-titanium burner, stable combustion and high atomization efficiency, all ensures the analysis accuracy.
