Instrument Features
More than 70 elements can be measured
Fast analyzing speed, 5-8 elements can be measured in one minute. Simultaneous analysis of multiple elements, customers are free to choose the number of elements and arrange the order of measurement.
Low detection limit, up to ppb level, even up to 0.7ppb for Ba.
Wide linear dynamic range, up to 6 orders of magnitude, high and low content can be measured simultaneously.
Low analysis cost, one bottle of argon can be used for 8 hours.
Total reflection achromatic optical system
The use of concave mirrors instead of convex lenses as optical focusing elements solves the problem of chromatic aberration caused by the different focal points of different elements and improves the efficiency of the optical system at the same time.
Wide wavelength range
Choose 4320 graduated gratings, the wavelength range is up to 190nm-460nm.
Choose 3600 graduated gratings for a wavelength range of 190nm-500nm.
Choose 2400 graduated gratings for wavelengths from 190nm to 800nm.
Fully automated design
High degree of automation, the whole instrument, except the power switch, all the functions of the instrument are controlled by computer, reliable, safe and convenient.
Automatic gas flow control
In the feeding system, the carrier gas, plasma gas and auxiliary gas are all controlled by advanced mass flow controller (MFC), which has the advantages of continuously adjustable flow rate and stable flow rate, etc. It ensures the stability of the feeding system and provides a strong guarantee for the stability of the light source.
Advanced Sampling System
The feeding system is highly efficient and stable, and can be equipped with various kinds ofatomizers and atomization chambers at home and abroad. It can be equipped with high salt atomizers, hydrofluoric acid resistant atomizers, etc. to meet the needs of different customers.
Stable waste liquid elimination system
Through the peristaltic pump for waste liquid exclusion, to ensure that the injection volume and waste liquid exclusion speed is consistent, customers can adjust the speed appropriately according to the need to ensure the stability of the injection system.
*Stable and advanced all-solid-state RF power supply
The RF power supply adopted by 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, which further improves the stability and safety of the instrument.
*Fast and accurate fully automatic matching function
The load terminal adopts self-developed full-automatic matching technology, which has the advantages of fast matching speed, high accuracy, etc. It ensures that the output power is maximized and added to the load, improves the efficiency of the power supply, which in turn improves the stability of the instrument and makes the whole ignition process convenient and simple.
*One-touch ignition
With the solid-state power supply and automatic matching technology, it perfectly realizes the one-key ignition function. Users only need to click the ignition button, the instrument automatically carries out gas blowing, gas flow checking, ignition, matching and many other actions, and real-time information will be transmitted to the customer, so that the customer can save the trouble.
*Automation of observation height adjustment
Different elements have different optimal observation heights, customers can adjust the observation height of the flame appropriately through the software according to experience or comparison, and get the best measurement effect at the best position.
Powerful graphical diagnostic function
Powerful graphical diagnostic function can help customers fully understand the current working status of the instrument, and through the appropriate parameter settings to observe the operation of the instrument under different conditions, in order to grasp the best measurement conditions.
Multi-element automatic measurement
Select each element to be measured, set the measurement parameters, and leave everything to the instrument, and finally get the measurement results of all elements directly, which is simple and hassle-free.
