Instrument introduction:

Flame Graphite Furnace Integrated Atomic Absorption Spectrometer is a high-performance, high-reliability spectral analysis instrument that has been independently developed, manufactured, and sold by Shandong Hengmei Electronic Technology Co., Ltd. for many years. It has a variety of atomization methods such as flame, graphite furnace, and hydride generation to choose from.

Performance features:

1. Integrated design

Adopting a series optical path design, the position of the flame graphite furnace atomizer is fixed, and the software is automatically switched without the need for hardware replacement and one-second switching, which avoids errors caused by mechanical switching and improves the stability and maintainability of the instrument.

2. Total reflection achromatic optical system

The concave mirror is used instead of convex lens as the optical focusing device of the instrument, which effectively solves the problem of different color differences in the focal points of different elements and improves the efficiency of the optical system.

3. C-T type monochromator

1800 lines/mm, 230nm blazing wavelength grating spectroscopic system.

4. Eight-element lamp lighthouse

Working with one lamp, up to seven lamps can be preheated, saving time for changing lamps and preheating, making element measurement faster and more convenient.

5. Fully automated design

Except for the main power switch, all functions of the instrument are monitored and controlled by computer, and the software automatically determines the optimum test conditions for each element.

6. USB3.0 communication method

The industry took the lead in adopting the USB 3.0 communication interface, which improved communication speed and made it compatible with the latest computer systems.

7. Background correction system

Element lamp and deuterium lamp dual switching and background deduction, with deuterium lamp and self-absorption two background correction mode, the background signal 1A, the ability to buckle the background more than 50 times.

8. The appearance is designed with a streamlined sheet metal process, which is simple and fashionable and beautiful

9. Fully functional and powerful analysis software. The user-friendly operation interface makes your operation easy. You can switch between Chinese and English Windows-style software interfaces, which can run perfectly under Windows XP, Windows 7 and other operating systems. Automatic qualitative and quantitative analysis, automatic calculation of element content, and automatic generation of test reports.

Flame System:

1. Pure titanium atomization chamber, pure titanium combustion head

It effectively prevents acid gas corrosion and has a longer service life.

2. High-efficiency glass atomizer

Adopt special high-efficiency glass atomizer, high atomization efficiency, easy maintenance and replacement.

3. Mass flow controller realizes acetylene flow control

The mass flow controller controls the flow rate of acetylene with an accuracy of 1ml/min and dynamically monitors the flow rate, making it easy to use, safe and reliable.

4. More safety measures to make sample analysis safer and more reliable

1) Acetylene leakage monitoring

2) Acetylene pressure monitoring

3) Air pressure monitoring

4) Burner head status monitoring

5) Flame status monitoring

6) Water seal status monitoring

Graphite furnace system:

1. Integrated design

The graphite furnace power supply and atomic absorption host are located in one instrument, which shortens the cable length, reduces the electromagnetic interference of the graphite furnace power supply to the outside world, and improves the heating efficiency of the graphite tube.

2. Graphite furnace has high temperature control accuracy and fast heating speed

Using high-power transformer, micro-resistance cable and light-controlled heating mode, and with software and hardware temperature correction system, the temperature control accuracy of high temperature section can reach ± 1%.

3. More safety measures to make sample analysis safer and more reliable

1) Cooling water flow monitoring

2) Carrier gas pressure monitoring

3) Graphite tube temperature monitoring

4) Graphite furnace temperature monitoring

4. Automatic carrier gas flow control

The internal gas and external gas of the graphite furnace are automatically controlled by the computer according to the software heating process.

5. 150-position turntable type graphite furnace automatic sampler

Polar coordinate turntable type automatic sampler for graphite furnace, which can realize a common automatic sampler between flame and graphite furnace, has high positioning accuracy, stable and reliable operation, and is convenient to use and maintain.
