Semimetal Spectral Analyzer Instrument Features
More than 70 elements can be measured
Fast analysis speed, 5 - 8 elements can be measured in one minute
Simultaneous analysis of multiple elements. Customers can freely choose the number of elements and arrange the measurement sequence. The detection limit is low, reaching the ppb level, and Ba even reaches 0.7ppb
Wide linear dynamic range, up to 6 orders of magnitude. High and low contents can be measured simultaneously
Low analysis cost. One bottle of argon can be used for 8 hours
Total Reflection Achromatic Aberration Optical System
Using a concave mirror instead of a convex lens as the optical focusing element solves the chromatic aberration problem caused by different focal points of different elements and improves the efficiency of the optical system at the same time.
Wide Wavelength Range
Selecting a grating with 4320 lines, the wavelength range can reach 190 - 460nm
Selecting a grating with 3600 lines, the wavelength range can reach 190 - 500nm
Selecting a grating with 2400 lines, the wavelength range can reach 190 - 800nm
Full Automation Design
High degree of automation. Except for the power switch, all functions of the whole instrument are controlled by a 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 efficient and stable. It can be equipped with various domestic and foreign nebulizers and spray chambers, and can be equipped with high-salt nebulizers, hydrofluoric acid-resistant nebulizers, etc., 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 appropriately adjust the speed as needed to ensure the stability of the standard injection system.
*Stable and advanced all-solid-state radio frequency power supply
The radio frequency power supply used in the instrument is an independently developed all-solid-state radio frequency 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 uses independently 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 utilization efficiency of the power supply, thereby improving the stability of the instrument and making the entire ignition process convenient and simple.
*One-key ignition
Combined with the solid-state power supply and automatic matching technology, the one-key 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 check, ignition, and matching, and transmits the information to the customers in real time, saving customers worry and trouble.
*Automated adjustment of observation height
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 good measurement results at the best position.
Powerful graphic diagnostic function
The powerful graphic diagnostic 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 best measurement conditions.
Automatic multi-element 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 trouble-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 interference, providing you with more choices and more reasonable recommendations, making the test more professional and accurate.
The software has independent intellectual property rights, powerful functions, and user-friendly operation
The software has powerful functions, with automatic switching function between Chinese and English, and can perform qualitative and quantitative analysis; it has data reprocessing function; it can automatically calculate the element content and automatically generate test reports; it has data screening function to eliminate unwanted data; the database management is perfect, and you can freely save and delete.
