CAAM-2001CSix lamp single flame atomic absorption spectrophotometerintroduction
1. Light source: Six lamp position light source, with automatic switching of lamp positions.
2. Stability and reliability: 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: It can achieve full transmittance, so your hollow cathode lamp can 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.
5. USB interface: The domestic atomic absorption spectrophotometer 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 spectrophotometers, 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 adjacent spectral line interference.

The invention, production, and application of glass high-efficiency atomizers have improved the sensitivity, detection limit, and stability of atomic absorption The application of flow injection hydride generator in atomic absorption spectrophotometer instrument has improved the sensitivity and detection limit determination efficiency of hydride atomic absorption method, and can partially replace atomic fluorescence spectrophotometer. 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.

7. Technology *, stability, and durability: The instrument won a gold medal at the BCEIA exhibition in 2003. Our company's instruments have been at large-scale instrument exhibitions and trade shows in recent years, and are among the atomic absorption instruments in the same category that dare to run baselines when turned on. When exhibiting in various parts of Xinjiang, the road conditions are extremely bumpy, and the car can be immediately turned on for testing. For atomic absorption spectrophotometers, this stability is rare among similar instruments.

Adjustment system: Fully automatic PC controlled six lamp brick tower, automatic alignment, automatic ignition.

Safety protection: It has automatic safety protection function, anti backfire automatic gas path protection, acetylene leakage alarm, automatic shutdown system, and automatic power-off in case of abnormalities.

Repeated measurement times: 1-99 times, calculate the average, provide standard deviation and relative standard deviation.

Result printing: Parameter printing, data result printing, graphic printing, can export WORD and EXCEL documents.

CAAM-2001CSix lamp single flame atomic absorption spectrophotometerThe interface is entirely in Chinese, with simple and convenient operation. The light position can be rotated and automatically ignited through software operation.

Communication interface: The computer communicates with the host via USB interface.

1. The instrument should be placed in a dry room and used on a sturdy and stable workbench. Indoor lighting should not be too strong. During hot weather, it is not advisable to use an electric fan to blow air directly onto the instrument to prevent unstable illumination of the bulb filament.

2. Before using this instrument, understand its structure and working principle, as well as the functions of each control knob. Before turning on the power, the safety performance of the instrument should be checked. The power wiring should be firm, and the power supply should be good. The starting position of each adjustment knob should be correct before turning on the power switch.

3. When the power is not yet connected, the pointer of the electricity meter must be on the "0" mark. If this is not the case, the calibration screw on the electricity meter can be used to adjust it.

4. Clean up. The atomic absorption method generally determines trace components, and special attention should be paid to preventing pollution, volatilization, and adsorption losses. The experimental environment and vessels have a significant impact on the determination, and attention should be paid to the cleanliness of the environment and vessels.

5. Prevent tempering

a. To prevent leakage of waste liquid discharge pipes, the outlet should be sealed with water.

b. The burner slit cannot be too wide. For a 100mm × 0.5mm slit burner, there is a risk of backfire when the slit width is greater than 0.8mm.

c. When using nitrous oxide acetylene flame, the acetylene flow rate should not be too small (not less than 2L/min).

d. The ratio of auxiliary gas to acetylene flow should not differ too much.

e. When transitioning from an air acetylene flame to a nitrous oxide acetylene flame, be careful not to reduce the acetylene flow rate too much.
