Atomic fluorescence spectrometer with auto-sampler
The upgraded automatic intermittent pump injection dual-channel atomic fluorescence spectrometer is used for elemental trace analysis. The dual-channel can measure two elements at the same time. memory effect. Fully automatic control, convenient, fast and accurate.
Applications
It is widely used in food hygiene monitoring, environmental sample testing, urban water supply and drainage testing, agricultural product testing, fishery and marine sample testing, geological metallurgy testing, cosmetic testing, drug testing, soil feed fertilizer, clinical medical testing As, Sb, Bi, Trace analysis of Hg, Se, Te, Sn, Ge, Pb, Zn, Cd, Au elements.
Upgrade functions
◆Configuration of morphological analysis preprocessing module can do morphological analysis of As, Hg, Se, Sb (and can analyze As and Sb morphologically at the same time);
◆Reserve the interface of the fixed sample injection measuring cadmium device, that is to directly detect the cadmium in the solid and liquid samples. (Relevant device models and color pages are required to provide evidence).
◆The interface of the solid sample injection mercury measurement device is reserved, which can directly detect mercury in solid and liquid samples.
◆Powerful Windows 7/XP Chinese and English software workstation. An expert help system is maintained to recommend the best instruments.
Specifications
1. Detection limit (DL): As, Se, Pb, Sn, Te, Bi, Sb < 0.01µg/L; Hg, Cd <0.001µg/L; Ge <0.05µg/L; Zn <1.0µg/L . Accuracy (RSD): <0.8%.
2. The linear range is three to four orders of magnitude; (the measured data curve needs to be provided)
3. It can be measured by two channels at the same time for trace analysis of eleven elements such as As, Sb, Bi, Hg, Zn, Cd;
Autosampler
1. The robot arm of the automatic sampler is automatically reset to zero when it is powered on;
2. The software automatically recognizes the autosampler when it is turned on;
3. The high-precision polar coordinate manipulator, the position deviation is within 0.1mm;
4. Turntable array 160-bit sample tray, using standard 10mL (1-158 bits), 30ml (159.160 bits) sample tubes;
5. Large-capacity current-carrying tank, small hole and low-diffusion cleaning position, effectively eliminate the contamination of the sampling needle residue on the carrier current and the cross-contamination between samples;
6. The cleaning position coordinate zero point reset, the minimum degree of cumulative error;
7. 3 motors independently control optocouplers to shorten the sampling time;
8. Stable operation, fast and accurate, low noise, no sample dripping phenomenon;
9. It can be upgraded to install UV online digestion device.
