The fully automatic 6 lamp holder is equipped with six independent lamp power supplies, which can be preheated separately;
Polymer spray chamber
Anti-corrosion spray chamber for polymer materials, resistant to acids and alkalis, including hydrofluoric acid, the highest sensitivity and stability in both organic and inorganic solutions;
Titanium burner
Titanium burner, optional 50mm and 100mm burner, air-cooled pre-mixing type, corrosion-resistant, high salt resistance, greatly improve flame efficiency and flame analysis accuracy;
Fully automated analysis
Safe ignition, extinguishing and switching can be completed automatically, the structure is reliable, and the failure rate is low, thus ensuring the sensitivity and reproducibility of the flame method.
The six-lamp position of the light source system is automatically converted, and the high-performance hollow cathode lamp can be directly used to improve the sensitivity of the flame analysis, automatically adjust the power supply parameters and the beam position, and automatically scan the wavelength and find the peak;
Software function
Highly intelligent software, powerful and friendly English operation interface. Fully automatic instrument and additional control, flame, graphite furnace working mode can be automatically switched, automatic optimization, automatic dilution; mouse operation, automatic setting menu data and calibration method;
Graphite furnace analysis system
Graphite furnace temperature control
Double temperature control of internal and external gas, 20-step linear or nonlinear temperature rise, ensuring the highest sensitivity of the element to be tested; enrichment in the furnace for 20 times, longitudinal light control to monitor the inner wall temperature of the graphite tube, up to 3000 °C.
High-tech indicators
The sensitivity of elemental test of TP-1800 atomic absorption spectrometer reaches the international best level, the sensitivity is ≤0.015μg/mL/1%; the baseline drift is less than 0.003Abs/30m, and the stability is better than 0.005Abs/4h;
Background correction system
The background correction is carried out by using the advanced hollow hollow cathode lamp and self-absorption buckle background to eliminate the interference of molecular absorption during low-level measurement, reduce the emission noise of the xenon lamp, prolong the service life and have excellent stability. When the background signal of the xenon lamp is 1A, the background capacity is deducted by >50 times;
