Product introduction: Bo tungsten-zhou elemental analyzer, no. 2400262, Beijing pharmaceutical inspection equipment (quasi-hui), 2011, 40. Product features: Tungsten boat, small power, the operation is simple with tungsten boat atomization device, with a small power, fast heating, without water cooling system, the characteristics of product direct measurements of lead, cadmium in view of the human body harmful elements. 1. Tungsten-zhou metal furnace: it has the characteristics of fast temperature rising and small power. The input power is 500VA and the input voltage is 220V, which can meet the requirement of rapid temperature rising during measurement without water cooling system. 2. Tungsten boat: made of metal tungsten, it is a kind of boat. It is resistant to high temperature and oxidation, and it is the core heating part of the metal furnace. 3. Open design: super-large injection hole, which makes injection operation simple and easy to learn; 4. High precision temperature control throughout the process: improved the reliability of test results; 5. Argon gas flow control: effectively eliminate background components, protect the tungsten boat and extend its service life; 6. High-temperature oxygenation technology: the carbon and other residues in the tungsten-zhou can be removed automatically, keeping the important conditions of analysis constant and making the measurement results accurate and reliable; 7. Self-priming background technology: simple structure, same optical path, same optical properties, good effect of background deduction, high precision of detection results; 8. Direct measurement of harmful elements lead and cadmium; 9. It can be equipped with automatic sampler. Technical parameters: Analysis method: tungsten-zhou atomic absorption spectrometry Absorbance range: 0 ~ 2Abs Wavelength: 190 nm ~ 650nm Baseline stability: after the instrument and element lamp are preheated for 30min at the same time, the baseline stability of each line should not exceed 0.009a when the atomizer is not working Sensitivity of the instrument: the test solution containing lead and cadmium was used as the test solution, and the absorbance of lead and cadmium should be greater than 0.055Abs and 0.025Abs respectively when the sample amount was not more than 50 chevrons Precision: the precision of lead and cadmium should not be more than 4.5% (Abs > 0.1); Automatic sampler: precision < 1% Background correction capability: when background absorption is close to 1.0Abs, the instrument has a background correction capability of more than 30 times Signal measurement type: double channel simultaneous measurement allows simultaneous measurement of lead and cadmium elements Measurement results: automatic calculation, sorting, storage, printing Overpressure category: category II Power supply: AC220 + / - 22V 50Hz + / - 1Hz Input power: 500VA Dimensions: 782mm (length) * 560mm (width) * 338mm (height) Working conditions: temperature 10 ℃ to 30 ℃ and atmospheric pressure 0.070 MPa to 0.106 MPa, no vibration environment, corrosive gas and electromagnetic interference Special software: automatic intelligent software, data collection, processing, test report printing
