AS-5800 Eight Lamp Single Graphite Furnace Atomic Absorption Spectrometer

AS-5800 Eight Lamp Single Graphite Furnace Atomic Absorption SpectrometerCharacteristics:

1. High stability: The baseline stability of the instrument is ≤ 0.002A/30min. * * compared to other atomic absorption spectrometer manufacturers at home and abroad. Baseline stability is a basic indicator for assessing an instrument, which determines a series of operating states of the host, such as noise, sensitivity, repeatability, etc.

2. High sensitivity: The sensitivity has reached * * * *, far exceeding the technical indicators of the same industry in China. My instrument has a sensitivity (1 μ g/ml copper Cu absorbance ≥ 0.28Abs).

3. High energy: The instrument lamp current is controlled at 3mA-5mA (8mA-12mA from other manufacturers), the spectral bandwidth is 0.2nm, and the negative high voltage is between 150V-350V to achieve full transmittance. This way, your hollow cathode lamp can be used for more than half of the time, greatly saving consumables and procurement costs.

4. USB interface: The domestic atomic absorption spectrometer is equipped with a USB interface, which is suitable for various types of computers and supporting office equipment, reflecting the forward-looking and compatibility of the instrument.

5. Multiple * * technologies: Our company has multiple * * in the manufacturing of atomic absorption spectrometers, such as high-performance hollow cathode lamps, glass high-efficiency atomizers, hydride generators, etc. The application of high-performance hollow cathode lamps has advantages such as high emission intensity, high measurement sensitivity, low detection limit, good stability, and disappearance of interference from adjacent spectral lines. The invention, production, and application of glass high-efficiency atomizers have greatly improved the sensitivity, detection limit, and stability of atomic absorption. The application of flow injection hydride generator in atomic absorption spectrometer instruments has achieved the level of sensitivity and detection limit of hydride atomic absorption method, with measurement efficiency *, and can partially replace atomic fluorescence spectrophotometer. Our * * products account for over 90% of the original suction * in the country.

6. Technology *, stability, and durability: Our company's instruments are among the few atomic absorption instruments in the same category that dare to run the baseline at large-scale instrument exhibitions and fairs in recent years. During the exhibition, the road conditions were extremely bumpy, and the car could be immediately turned on for testing. For atomic absorption spectroscopy instruments, this stability is very rare among similar instruments.

7. Humanized information processing software: Our instrument data processing software was developed by Deng Bo, a theoretical expert in the field of atomic absorption analysis in China and a professor at Tsinghua University. It integrates new achievements in data processing at home and abroad, combined with practical experience in the field of atomic absorption spectroscopy in China, to provide reliable data processing results. The designed software operation is both convenient, fast, and efficient, making it a masterpiece in atomic absorption software.

8. Integrated design of graphite furnace system and host: The automatic switching between graphite furnace system and flame atomizer (HS6 type) makes it very simple and fast to switch from the system to sample testing. Greatly saves analysis time. And an automatic sampler can be optionally selected.
