Key features

• Stable and reliable with the functions of integral holding, peak height and area, auto zero adjusting, deuterium lamp background correction, multi-linear and nonlinear curves fitting, various parameters and working curves displayed in screen and report printing, etc. It is equipped with interface for externally linking PC.
• Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration.
• Double-beam system can automatically compensate the light source drift and wavelength drift caused by the variation of temperature and electronic circuit drift so as to reach a good basic line stability.
• The burner is made of new type titanium alloys, anti-corrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling.
• The gas circuit is equipped with pressure indication, high-precision pressure and flow regulation, gas cut-off, power failure, backfire prevention functions, and logic interlock protection devices.
• For methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation.
• It can be used to analyze various types of samples, including environmental samples such as water, soil, and air, as well as food samples, biological samples, and industrial materials. This instrument is mainly used to determine major and trace metal elements in various samples.
• This instrument supports multiple analytical modes, including flame spectroscopy, graphite furnace spectroscopy, and hydride generation.
• The instrument should be operated under the following environmental conditions:
• Ambient temperature: 10℃ to 30℃
• Relative humidity: Not exceeding 85%Other requirements: Avoid vibration, magnetic field interference, corrosive gases, and heat sources.
• The instrument needs to be connected to an acetylene cylinder and an air compressor. Be sure to use a dedicated pressure reducing valve and ensure good ventilation.
• The problem might be a faulty lamp power supply, a broken lamp holder wiring, or poor contact between the lamp holder and the socket. Check the lamp power supply, connecting wires, and related connectors in sequence.
• This is caused by oxides or impurities on the cathode surface. Try increasing the lamp current to a few milliamps until the sparking stops. If this doesn’t work, replace the lamp.

Applications

• Quantitative or qualitative laboratory analysis
• Research, method development, and routine quality control
• Application-specific testing with suitable accessories and methods
