1Food additive atomic absorption spectrophotometerbasic function

1. Light source: using high-performance specially coded hollow cathode lamp

2. Optical path: Adopting a short focal length non-uniform optical path system

3. Duty cycle: Adopting adjustable duty cycle, automatically selecting the best duty cycle to achieve the best excitation effect

4. Background subtraction: Using the small background subtraction function, it can automatically deduct background interference caused by impurities, astigmatism, and flames

5. Automatic sampler: a static noise 3D track automatic sampler with flexible configuration of optional sample positions

6. Instrument upgrade: Users who configure HG-AFS spectrometers can choose to upgrade to HG-FLAME-AFS spectrometers to broaden the range of detected elements (adding detection functions for elements such as Au, Ag, Cu, Co, Cr, Ni, etc.)

7. Reserved interface: Reserved for use with instruments such as chromatography and morphology analyzers.

8. Workstation: A complete operating system in both Chinese and English, implementing various curve methods and testing methods, recommending the best instrument testing conditions, and expert assistance functions. The functions include graphical display and playback of test data, data statistics and queries, various graphics, data, page saving, and printing.

IIFood additive atomic absorption spectrophotometercharacteristic:

1. Hydride generation system

The single pump dual channel continuous flow injection method for hydride generation avoids errors caused by memory effects in samples with different contents at the same testing time. A designed A-type multifunctional reaction module device is adopted, which integrates hydrogenation reaction, bubble elimination, gas-liquid separation, and automatic discharge of waste liquid.

2. Gas transmission system

Using a short-range direct gas transmission system, the measured element hydrides, hydrogen gas, and carrier gas generated by the hydrogenation reaction are efficiently transmitted to the atomizer

3. Atomization system

Adopting a double-layer quartz shielded atomizer, the three-dimensional adjustment mechanism makes it more convenient, fast, and accurate to adjust the position of the atomizer, achieving the best excitation effect and fluorescence signal reception effect.

4. Circuit system

Adopting modular design of large-scale integrated circuits, cathodic lamp dual channel coding selection protection, overvoltage, overcurrent, and open circuit protection.

5. Appearance design

Adopting the internationally popular 3U chassis design, the overall structure is simple, easy to operate, and has good electromagnetic compatibility.
