Advanced Graphite Furnace Temperature Controlling Technology

The bringing in of PTD technology can effectively overcome the influence on the temperature rising process caused by the voltage fluctuation and the resistance change to make a more accurate controlling process. The combination of the 3ms/time fast sampling technique can make more accurate and reliable testing data
The fast heating capacity can improve the flexibility of the elements further
Use the ordinary power source of 220V without the need of dynamic power of 380V
The maximum procedure heating capacity setting of 20 levels can make a more convenient and easier test of different samples Three grades of adjustable gas flow can accustom to more application needs
Can timely alarm when the gas and water are stopped and insufficient gas and water, can avoid equipment damage and measuring error

Safe, Reliable, and Convenient Flame System

EPC can control the flow of Acetylene (C2H2) more accurately and it is a kind of system that also can operate easily
Efficient a Tomi zati on s ys tern enables a higher Sensitivity. The whole operating system has high security as the fire safety system can alarm whenever the electricity is cut off, abnormal flame occurs, a lack of pressure happens or the burner does not match well. And it will automatically turn off the gas, prohibiting tempering. Thus it keeps the operation people and equipment from harm and damage.

FAQ

Ignition failure is usually related to the following factors, which can be checked in the following order:

1. Water Seal Check:Ensure there is sufficient water in the waste liquid line to form a water seal. This is an important safety feature of the instrument; without a water seal, the ignition function will be locked.

2. Gas Source and Pressure: Check if the acetylene cylinder output pressure is between 0.08-0.12 MPa. Pressure that is too high or too low will cause ignition failure. Also, confirm that the air compressor pressure is normal.

3. Photosensitive Probe Interference:The AA4530F is equipped with a flame detection probe. If the ambient light is too strong (such as direct sunlight), it may be mistakenly identified as a flame signal by the probe, interfering with the ignition logic. In this case, try drawing the curtains or appropriately blocking strong external light.

4. Safety Interlock: Check if the burner head is installed correctly. The instrument has safety alarm functions for burner head mismatch and gas leaks, and will automatically cut off the gas supply in case of abnormalities.

This is usually caused by the instrument’s safety protection mechanism being triggered. The AA4530F has an automatic flame extinguishing protection function. When the photosensitive probe cannot detect the ultraviolet signal of the flame, it will immediately cut off the acetylene gas supply to prevent backfire. Common causes include: insufficient acetylene pressure, interruption of air supply (such as the air compressor not starting in time), or a broken water seal in the waste liquid pipe.

Based on actual cases and manufacturer guidance, there are three common causes of unstable dynamic baselines after ignition (such as fluctuations from -0.003 to -0.05):

1. Dirty combustion system: Dirt in the atomizer or burner head causes fluctuations in atomization efficiency. Clean the combustion system with a 10% nitric acid solution for 5 minutes, then rinse with deionized water for 5 minutes.

2. Clogged drain pipe: Check if the waste liquid drains smoothly; accumulated liquid can cause unstable flame conditions.

3. Element Lamp Issue: The zinc lamp (wavelength 213.9nm) is close to the ultraviolet region and is significantly affected by the flame background. Try checking if the negative high voltage is too high, appropriately increasing the lamp current to reduce the negative high voltage, or adjusting the burner head height to find the optimal observation position.

Some users have reported individual differences in the stability of this model. To ensure optimal performance, we recommend:

1. Sufficient warm-up: Allow sufficient warm-up time for the light source and circuit system after powering on (usually no less than 30 minutes).

2. Environmental control: The instrument uses an integrated suspended optical platform design to improve shock resistance, but vibrations of the experimental platform and strong airflow disturbances should be avoided as much as possible.

3. Regular calibration: Regularly check the instrument’s characteristic concentration and precision using a copper (Cu) standard solution (RSD should be ≤0.5%).

These are the parts most prone to getting dirty daily. You can disassemble and clean them yourself, but please pay attention to the following methods:

1. Sampling needle: First, turn off the power. Unscrew the metal sampling needle, soak it in a special cleaning solution for 20 minutes, then rinse it repeatedly with deionized water, and finally dry it with nitrogen. Be careful to prevent water from entering the circuitry.

2. Burn head: The burner head is mostly a snap-on design and can be carefully removed. If gaps or small holes are blocked, gently unclog them with a fine needle, then soak it in alcohol and dry it with nitrogen. A “click” sound indicates it is securely in place when reinstalling.

Regularly monitor the lifespan of the hollow cathode lamp (element lamp). Replace it when the lamp energy significantly decreases or the noise increases. The capillary tube and impact ball of the nebulizer are also wear parts. If the atomization efficiency is still poor after cleaning, consider replacing them. In addition, the air filter element needs to be cleaned or replaced regularly.

Atomic absorption spectrometry uses flammable and explosive gases and must comply with the following regulations:

  • Cylinder Storage: Acetylene cylinders must be stored separately from the instrument in a well-ventilated room, and open flames are strictly prohibited.
  • Pressure Limitation: The output pressure of the acetylene cylinder must not exceed 0.12 MPa.
  • Proper Ignition: The acetylene flow rate during ignition must not exceed 3 L/min, and it is essential to ensure that the waste liquid pipe has a water seal.
  • Unattended Operation: After ignition, the operator must not leave the instrument unattended for an extended period.
  • Proper Flame Extinguishing: To extinguish the flame, first close the main valve of the acetylene cylinder, allow the remaining gas in the pipeline to burn out naturally, and then close the valve via software.
