The RF power supply used in the instrument has small size, high output efficiency, stable output power, and various safety protection functions such as water, gas, and overload, greatly improving the safety of the instrument and reducing its failure rate.

3. Fully automatic ignition and matching technology

The software can automatically ignite with one click, and all parameter settings changes are automatically completed. Combined with automatic matching technology, the ignition success rate is high and the operation is simple.

4. Intelligent flame monitoring function

The instrument is configured with sensitivityHigh fiber optic sensors can monitor the working status of flames in real time while the instrument is in operation. In case of abnormal flameout, the instrument can automatically shut down.

5. Ultra high resolution optical path system

The instrument is equipped with an imported grating with ultra-high resolution 4320 engraved lines, which is matched with*The optical path adjustment technology reduces the resolution of ordinary instruments from about 0.008nm to within 0.005nm, and the ultra-high resolution ensures that there is no mutual interference between test elements.

6High precision constant temperature system

The overall optical path of the instrument is protected by a precision constant temperature system, and the temperature control can be set in real time according to the actual environmental temperature of the customer's laboratory, without the need for long-term continuous adjustment. The temperature control accuracy is ≤± 0,1 ℃, and the precision constant temperature system ensures the stability of the optical path, resulting in more stable test data.

7. High precision airflow control system

The plasma gas, auxiliary gas, and carrier gas used in the operation of the instrument are all controlled by high-precision mass flow controllers (MFCs), which have continuously adjustable flow rates and high accuracy in outputting airflow, ensuring the accuracy of test data.

8Peristaltic pump injection device

The instrument is equipped with a high-precision peristaltic pump with twelve rollers, which can ensure the accuracy of sample injection and prevent liquid accumulation at the same time. The rotational speed of the peristaltic pump is continuously adjustable to meet various testing requirements of customers.

9. Automatic adjustment of observation position

The instrument adopts a two-dimensional mobile platform design, which can adjust the position of the torch tube in real time through software. The optimized observation position can be found through feedback signal values to obtain strong sensitivity and accurate testing results.

10. Ultra low usage cost

When the instrument is not in operation, the power supply, cooling water tank, and gas are all turned off without any cost. The instrument can be used immediately without the need for prolonged preheating of the optical path. Use argon gas with purity of 99, 99*%Okay, no need for high-purity argon at 99% or 999%, cost savings of at least one-third.

11. SensitivityHigh detector

The instrument is equipped with a high-sensitivity imported photomultiplier tube (PMT) as the detector, which can automatically set test parameters for different elements to achieve ideal detection state and provide accurate test results. No need for refrigeration, no need for blowing, long service life.
