Atomic fluorescence spectrophotometer

Atomic fluorescence spectrophotometerPerformance characteristics:

1. Measurement method

Dual channel, single element testing, dual element simultaneous testing optional, dual element simultaneous measurement, improves instrument analysis speed.

2light source system

Bundle pulse power supply method, specially designed high-intensity coded hollow cathode lamp, automatic identification of single and double cathode lamps, and automatic adjustment of the energy ratio of double cathode lamps.

3. Atomizer

Adopting a double-layer shielded quartz atomizer and an argon hydrogen flame low-temperature automatic ignition device, the imported ignition furnace wire has a long service life and low cost, which greatly reduces the memory effect while improving the stability of the measured element.

4Metering system

Adopting a high signal-to-noise ratio photoelectric detection system and a non dispersive fully enclosed light path system with short focal length lens focusing.

5. Gas liquid separator

Chemical gas-phase gas-liquid separation device, where reactants are fully mixed and in contact, automatically removes a large number of bubbles generated by complex organic components in the body sample online; Secondary gas-liquid separator: equipped with a device for removing water vapor, effectively eliminating water vapor.

6Harmful element capture trap device for recovering residual pollutants

We use a harmful element capture trap device in atomic fluorescence analysis to recover residual pollutants in the environment (such as arsenic, lead, etc.), especially for the recovery of mercury vapor. It not only avoids secondary pollution in the laboratory but also further protects the safety of instrument operators.

7. It has automatic online detection function.

Atomic fluorescence spectrophotometerApplication scope:

Widely used for trace analysis of As, Sb, Bi, Hg, Se, Te, Sn, Ge, Pb, Zn, Cd, Au elements in food hygiene testing, environmental sample testing, urban water supply and drainage testing, agricultural product testing, fishery and seawater sample testing, geological gold detection, cosmetics testing, drug testing, soil feed and fertilizer testing, and clinical medical testing.

upgrade function

1. The pre-processing module for configuration morphology analysis can perform morphology analysis of As, Hg, Se, and Sb (and both As and Sb morphologies can be analyzed simultaneously).

2. Reserve a solid injection cadmium detection device for direct detection of cadmium in solid and liquid samples (relevant device models and color page evidence need to be provided).

3. Conditions and preferred methods, as well as guidelines for sample pretreatment, standard solution preparation, interference elimination, etc; Fully automatic control, convenient, fast, and accurate.

4. The robotic arm of the powered automatic sampler automatically resets to zero.

5. The software automatically recognizes the automatic sampler upon startup.

6. The high-precision polar coordinate robotic arm has a displacement deviation of within 0.1mm.

7. Rotary array with 160 sample disks, using standard 10mL (1-158 positions) and 30ml (159.160 positions) sample tubes.

8. Large capacity flow channel, small hole low diffusion cleaning position, effectively eliminates contamination of the current by residual sampling needles and cross contamination between samples.

9. Reset the zero point of the cleaning position coordinates to minimize accumulated errors in movement.

10.3 motors independently control optocouplers to shorten sampling time.

11. Smooth operation, fast and accurate, low noise, and no sample dripping phenomenon.

12. Upgradeable installation of UV online digestion device.
