Switch device of fixed light source (patented technology)

The switch device of fixed light source was invented by Sir. The replacement of element lamp was realized by rotating optical device, which overcame the damage caused to low melting point light source by mechanical rotating disc lamp holder in the rotation process, and effectively improved the service life of element light source.

The power and stability of the instrument can be improved by eliminating aberration effect.

Designed with extra capacity, it can be equipped with 8 element lamps, one deuterium lamp and one tungsten lamp at the same time, which is convenient for detection.

Pure titanium flame atomizer

The thermal area of the grid-cooled pure titanium burner is increased, the balance temperature of the burner is reduced, and the influence of high-salt and high-alkali samples on the next test is effectively alleviated. Titanium has better corrosion resistance than stainless steel, which can effectively prolong the service life of burner.

The injection tube of the indium platinum-iridium alloy atomizer adopts the platinum-iridium alloy material with strong corrosion resistance, which can guarantee that it will not be damaged in the long-term measurement of strong corrosion samples and maintain the sensitivity of the instrument.

The pure titanium premix chamber of the blank tangential intake structure utilizes aerodynamic principles to introduce the gas from the annular tangent of the premix chamber. The eddy current formed makes the mixture of the sample, gas and auxiliary gas more uniform, which is conducive to improving the detection accuracy of the instrument.

When there is no water seal, the water seal system with multiple alarms can alarm and turn off the gas switch in a timely manner, so as to guarantee the tempering phenomenon caused by the leakage of gas through waste liquid pipe. When the liquid level of the waste bucket reaches a certain height, it will timely alarm.

The inner wall of the drain line is lined with FEP material (fluorinated plastic), which can bear any corrosive liquid.

Design of isolated graphite furnace structure (patented technology)

The non-working condition of the graphite furnace atomizer is isolated outside the flame atomization work area, which avoids the measurement error caused by the pollution of the graphite furnace atomizer caused by the discharge of a large amount of high concentration waste.

The pneumatic graphite tube locking mechanism makes it easy and fast to change and lock the graphite tube. At the same time, it is designed to make the graphite tube in good contact with the graphite electrode to ensure the accuracy of temperature control.

The fast heating of the atomizer can be achieved effectively by the control mode of electric feedback and optical feedback.

The background correction systems of deuterium lamp and self-absorption in the instrument are effectively complementary to each other.

Rotary multi-function automatic sampler (patented technology)

The swing arm automatic sampler is connected with the instrument by means of rotating shaft. When the automatic sampler is enabled, it only needs to be inserted into the front side of the instrument.

The injection device is not only a graphite furnace atomizer, but also used for hydride atomizer and uv spectrophotometer.

The unique automatic dilution function of the automatic sampler ensures the uninterrupted analysis of the wide range of concentration.

Real-time monitoring of the state of the sampler by the visible system of the power graphite furnace.

Integrated design of hydride generator (international invention patent)

The built-in hydride technology has created a world precedent for atomic absorption instrument to integrate flame, graphite furnace and hydride atomizer. It has changed the tedious operation mode of external hydride to be repeatedly dismantled and assembled, and effectively improved the sensitivity and accuracy of atomic absorption instrument to detect toxic and harmful elements such as mercury, arsenic and lead.

With the development of integrated hydride generator by utilizing the advanced microfluidic technology in the world, Mr. Liu has a small volume and high reliability.

Characteristics of hydride generator

S hydride generator in atomic absorption spectrometer is one of the three important atomization device, can be in the material trace amounts of poisonous and harmful elements such as mercury, arsenic, lead, and some of the precious metal elements such as antimony, bismuth, selenium, germanium, titanium, such as accurate measurement, due to the atomization equipment with less interference, high sensitivity, measured accurately, fast analysis speed, etc., are widely used in areas such as water, food, environmental protection, quality inspection, many detection methods are especially in our country which is formed by the internationally recognized as the standard analysis method.

Integrated gas control system (international initiative)

S atomic absorption spectrometer in the stability and control accuracy of the gas is an important factor to ensure measurement accuracy, and high failure rate of link, the integration of the gas control system USES a high gas flow controller, sensors, electromagnetic valve, filter, such as import components, forming a small volume, reliable performance of the intelligent control unit, under computer control can realize automatic ignition, automatic regulation of gas flow and steady flow control, gas leak detection and protection, and other functions. Precise gas flow setting and steady flow control subvert the idea that traditional instrument working curve cannot be reused.

Multiple gas safety protection measures

The multi-safety interlock design completely eliminates the extreme situation.

In the practical leak detection function, the sealing condition in the gas pipeline can be detected by the computer. Once gas leakage is found, it can further distinguish the leakage points in the internal and external pipelines of the instrument, making the gas leak detection more effective

Easy.

The air pressure is monitored and warned in real time, and the gas source is cut off automatically when the combustion gas pressure is lower than the safe value.

The flame is monitored in real time, and the gas source is cut off automatically when abnormal or extinguishing is found.

The instrument is equipped with an acetylene sensor, which automatically cuts off the gas source when the acetylene gas leakage is detected inside the instrument.

The advanced conical locking device is used in all the gas pipeline interfaces in Shanghai, which eliminates the potential risk of gas leakage in the pipeline interfaces.

The last safety protection measure of the flame atomizer design is the explosion-proof mechanism. In case of gas tempering, the explosion-proof membrane in the explosion-proof mechanism is broken, which can effectively guarantee the safety of human beings and equipment.

High quality instrument control and data acquisition system

Automatic control of all parts of the instrument can be achieved by simply clicking the corresponding function keys in the control software interface.

The test system is built into the instrument, with only the display screen and keyboard and mouse to complete the control, data acquisition and calculation of the instrument.

The software operates the Chinese interface, and the client has no trouble using it.

With the measurement wizard function, you will be prompted to set the customer's parameters to avoid forgetting to set the necessary parameters for measurement.

Free analysis contains more than 70 element analysis methods, various calibration curve methods are available for selection, the measurement data can be edited arbitrarily and read directly in EXCEL format, and the original data file in TXT format is provided. The multi-level user interface meets the needs of operators at different levels.
