Advanced horizontal heating graphite furnace design
The domestic use of transverse heating graphite furnace for atomic absorption has achieved uniform temperature distribution of graphite tubes, reducing chemical interference and memory effects. This not only ensures improved atomization efficiency but also extends the service life of graphite tubes, ensuring analysis accuracy.
Highly automated products have extraordinary performance: coupled with the powerful analysis assistant AAWin2.0 software, the operation is more accurate and simple.
Adopting an eight lamp automatic switching turret and pre-set optimized working conditions for hollow cathode lamps, it can facilitate multi-element detection;
Automatic flow setting, automatic ignition, automatic shutdown protection;
Automatically adjust negative high voltage and lamp current, and balance the two paths of light energy automatically;
Automatically set flame height and atomizer position, select analysis conditions to ensure reliable analysis results;
Automatic conversion of spectral bandwidth, available in five levels: 0.1nm, 0.2nm, 0.4nm, 1.0nm, and 2.0nm;
Automatic wavelength scanning and peak searching;
Automatically set gas flow rate, select element analysis * fuel assist ratio;
When using the deuterium lamp to fasten the background, it automatically switches to the semi transparent and semi reflective mirror device, and can also make angle adjustments to ensure the coincidence of the two light spots and the effect of fastening the background;
Expandable flame automatic sampler, graphite furnace automatic sampler, hydride generator, laughing gas control box, cooling circulating water device.
Reliable security protection system: adopting multiple security protection measures to ensure the safety of operators.
Reliable position recognition: equipped with combustion head installation detection and drainage level detection, ensuring * protection for operators during flame combustion.
Comprehensive graphite furnace protection measures: Simultaneously detect the pressure of the protective gas and the flow rate of the cooling water. In case of abnormal fluctuations, immediately stop heating and sound an alarm.
Cooling water flow monitor: Ensure sufficient cold water flow to cool the furnace body before heating the graphite furnace.
Real time flame monitoring: The flame monitor monitors changes in the flame at any time. When an unexpected power outage or incorrect operation causes the flame to extinguish, the acetylene gas circuit will immediately shut down automatically and prompt an alarm.
Acetylene leakage protection system: 24-hour monitoring of the acetylene concentration inside the instrument and in the working environment. Once the acetylene exceeds the warning concentration, the acetylene gas path will automatically close and an alarm will be prompted. (Acetylene leakage cannot start the machine)
Real time monitoring of abnormal pressure: When using air acetylene flame analysis, the air pressure monitor constantly monitors changes in air pressure. When an abnormal situation occurs, the acetylene gas circuit will immediately shut down automatically and prompt an alarm.
Excellent scalability: It can easily and quickly respond to diverse and complex sample analysis systems, easily meeting your various analysis needs.
