Single flame atomic absorption spectrometerFeatures:

1. Light source: Three position light source, manually switched and adjusted.

2. Stable and reliable: The baseline stability of the instrument is ≤ 0.002A/30min. 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.

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 allows the hollow cathode lamp to be used for more than one-third of the time, greatly saving consumables and procurement costs.

4. Imported components improve instrument performance: imported original photomultiplier tubes and imported original 1800 line gratings.

5. 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.

6. Multiple technologies: Our company has multiple countries in the manufacturing of atomic absorption spectrometers, such as high-performance hollow cathode lamps, glass high-efficiency atomizers, hydride generators, etc.

7. Technical *, stable, and durable.

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 improved the sensitivity, detection limit, and stability of atomic absorption.

Flow injection hydride generatorSingle flame atomic absorption spectrometerThe application of the instrument has enabled the sensitivity and detection limit of hydride atomic absorption spectrometry to reach a good level, with measurement efficiency *, and can partially replace atomic fluorescence spectrometers. Our products account for over 90% of the country's raw materials.

The present utility model relates to a high-precision transmission mechanism for a monochromator of an atomic absorption spectrophotometer (No. 2016205322788), comprising a worm gear cover and a worm gear installed inside the worm gear cover, a worm gear cover and a worm gear installed inside the worm gear cover. The worm gear cover and the worm gear cover are installed on one side of the bottom plate, and the worm gear cover are connected to the worm gear cover. One end of the worm gear passes through the worm gear cover and is connected to the motor shaft through a coupling. The main shaft is coaxially fitted in the center hole of the worm gear, and the output end of the main shaft passes out of the bottom plate and is connected to the monochromator. This utility model adopts the transmission mode of worm gear to control the monochromator, which improves the accuracy of the spectroscopic system.
