Fully Automated Design
High degree of automation. Except for the power switch, all functions of the whole instrument are controlled by the computer, which is reliable, safe, and convenient.
Automatic Gas Flow Control
In the sampling system, the carrier gas, plasma gas, and auxiliary gas are all controlled by advanced Mass Flow Controllers (MFCs), which have the advantages of continuously adjustable flow and stable flow, ensuring the stability of the sampling system and providing a strong guarantee for the stability of the light source.
Advanced Sampling System
The sampling system is highly efficient and stable. It can be equipped with various domestic and international nebulizers and spray chambers, including high-salt nebulizers and hydrofluoric acid-resistant nebulizers, to meet the needs of different customers.
Stable Waste Liquid Exclusion System
The waste liquid is excluded through a peristaltic pump to ensure that the sampling volume is consistent with the waste liquid exclusion speed. Customers can adjust the speed appropriately as needed to ensure the stability of the standard injection system.
*Stable and Advanced All-Solid-State RF Power Supply
The RF power supply used in the instrument is an independently developed all-solid-state RF power supply, which has many advantages such as small size, high efficiency, stable output power, and various protection functions. It further improves the stability and safety of the instrument. *Fast and Accurate Automatic Matching Function
The load terminal adopts independently developed automatic matching technology, which has the advantages of fast matching speed and high accuracy. It ensures that the output power is maximally applied to the load, improves the utilization efficiency of the power supply, thereby improving the stability of the instrument and making the entire ignition process convenient and simple.
*One-Button Ignition
Combined with the solid-state power supply and automatic matching technology, the one-button ignition function is perfectly realized. Users only need to click the ignition button, and the instrument automatically performs many actions such as gas purging, gas flow inspection, ignition, and matching, and transmits the information to the customer in real-time, saving customers time and effort.
*Automated Observation Height Adjustment
Different elements have different observation heights. Customers can appropriately adjust the observation height of the flame through the software based on experience or comparison to obtain better measurement results at the optimal position.
Powerful Graphical Diagnosis Function
The powerful graphical diagnosis function can help customers fully understand the current working status of the instrument and observe the operating conditions of the instrument under different conditions through appropriate parameter settings to grasp the optimal measurement conditions.
Multi-Element Automatic Measurement
Select the elements to be measured, set the measurement parameters, and leave everything to the instrument. Finally, directly obtain the measurement results of all elements, which is simple and time-saving.
*Powerful Database Management
It has thousands of spectral lines. You can select appropriate spectral lines according to your needs and preferences to avoid possible interferences. It provides you with more choices and more reasonable recommendations, making the test more professional and accurate.
