Fully automated design
The automation level is high, and all functions of the entire instrument, except for the power switch, are controlled by a computer, which is reliable, safe, and convenient.

Automatic control of gas flow rate
In the injection system, the carrier gas, plasma gas, and auxiliary gas all use mass flow controllers of *（MFC）To control, it has the advantages of continuously adjustable flow rate and stable flow rate, ensuring the stability of the injection system and providing strong guarantee for the stability of the light source.

*The sampling system
The injection system is efficient and stable, and can be equipped with various atomizers and atomization chambers at home and abroad. It can also be equipped with high salt atomizers, hydrofluoric acid resistant atomizers, etc., to meet the needs of different customers.

Stable waste liquid removal system
By using a peristaltic pump for waste liquid removal, the injection volume is ensured to be consistent with the waste liquid removal speed. Customers can adjust the speed as needed to ensure the stability of the injection system.

*Stable all solid state RF power supply
The RF power supply used in the instrument is a self-developed all solid state RF power supply, which has many advantages such as small size, high efficiency, stable output power, and various protection functions, further improving the stability and safety of the instrument.

*Fast and accurate fully automatic matching function
The load terminal adopts self-developed fully automatic matching technology, which has the advantages of fast matching speed and high accuracy, ensuring that the output power is maximally added to the load, improving the efficiency of power supply, thereby enhancing the stability of the instrument, and making the entire ignition process simple and convenient.

*One click ignition
Combined with solid-state power supply and automatic matching technology, the one key ignition function has been achieved. Users only need to click the ignition button, and the instrument will automatically perform various actions such as gas blowing, gas flow check, ignition, matching, etc., and transmit the information to customers in real time, making customers worry free and worry free.

*Observe the automation of height adjustment
Different elements have different optimal observation heights. Customers can adjust the flame observation height appropriately through software based on experience or comparison, and obtain good measurement results at the optimal position.

Powerful graphical diagnostic function
The powerful graphical diagnostic function can help customers fully understand the current working status of the instrument and observe its operation under different conditions through appropriate parameter settings, in order to grasp the best measurement conditions.

Multi element automatic measurement
Select the various elements that need to be measured, set the measurement parameters, hand everything over to the instrument, and finally obtain the measurement results of all elements directly, which is simple and convenient.

*Powerful database management
Having thousands of spectral lines, you can choose appropriate spectral lines according to your needs and preferences, avoiding possible interference, providing you with more choices and more reasonable recommendations, making testing more professional and accurate.
