CATEGORY:
• Flame and graphite furnace integrated series
PRODUCT FEATURES:
• Flame and graphite furnace integrated machine; double atomizer series integrated design; no switching; users do not need to frequently adjust the position of graphite furnace injector;
• Dual light source design; flame and graphite furnace have independent light sources respectively, which overcomes the disadvantages of long optical path and large energy loss of traditional series all-in-one machine, and ensures that both analysis modes can have better optical design;
• Deuterium lamp background correction technology is adopted for flame and graphite furnace; specially imported deuterium lamp ensures its stable operation in modulation mode; strong energy and stable luminescence;
• With flame emission function, it can measure easily-ionized metal elements by emission method;
• Flame and graphite furnace atomization modes are automatically switched by software; relevant configuration and instrument conditions are automatically matched;
• Two sets of 8-Lamp slip ring rotating lighthouses can realize the simultaneous preheating of eight lights;
• It has the functions of power on self-test, automatic slit switching, automatic peak setting, automatic lamp position, automatic recommendation for analysis conditions, etc.
• Automatic energy balance technology, with D2 energy automatic attenuator, ensures that the cathode lamp is
matched within the scope of use, and ensures D2′ s service life and instrument’ s working condition;
• The graphite furnace has built-in power supply, longitudinal heating, light-controlled temperature rise and temperature calibration functions, and is designed with over temperature alarm of furnace body, low gas pressure alarm, broken or unclamped graphite tube alarm, etc;
• Equipped with 64 position graphite furnace automatic sampler; double syringe pump; vertical injection; visible injection process;
• The system of the flame part is stable and reliable with the design of integrated automatic water seal, automatic ignition, flame monitoring, gas leakage alarm, etc.;
• Equipped with gas shutdown button in case of accident;
• Can be equipped with hydride generator.
