Excellent Yi Yi Sex can

1.This instrument adopts the classic peristaltic pump continuous injection method of hydride atomic absorption spectrometry; Touchscreen microcomputer control; Adopting a two-stage gas-liquid separation device, with low detection limit, extremely wide linear range, and stability (RSD) reaching3%The sensitivity indicators below meet or exceed those of the flow injection type. After the generator is turned on, it has a self check function and will automatically alarm if there is a fault.

2.This machine adopts microcomputer touch screen control, and all the data that needs to be adjusted are adjusted by clicking on the touch screen (quartz tube temperature, peristaltic pump working status, peristaltic pump start, peristaltic pump speed and rotation time, pipeline cleaning, etc.). The use and operation are displayed in real-time in Chinese, which is easy and fast to understand.

3.High sensitivity: With high sensitivity and detection limit, it can achieve the same level as similar hydride generatorstallLevel.

Here is the sensitivity of any selected generator of this type（ng/mL/1%A）Actual measurement data:

Note: This measurementThe data is from Beijing HaotianhuiinstrumentProduced by a limited companyCAAM2001Measured by a multifunctional atomic absorption spectrometer and a high-performance hollow cathode lamp. Factory inspection and determination of arsenic, indicators:<0.20ng/mL/1%AThe actual control isAbout 0.12. The sensitivity and absorbance values measured vary depending on the performance of the atomic absorption host.

4. Good stability; factory specificationsRSDRelative standard deviation, i.e. coefficient of variation<3%(Actual can be less than2%)Determination of arsenic; The absorbance is0.18-0.5between,determination11The second calculation.

5. Low detection limit; with3 Calculation of multiple standard deviations,The value is approximately the sensitivity value2/3(unitng/mL)Can meet the low to medium requirements of the sample0.01－0.1ppmMeasurement requirements.

6. High efficiency; Excluding sample pre-treatment,Continuous injection for repeated determination5Secondly, the time is less than40In seconds.

7. The usage conditions of the peristaltic pump can be set according to user needs, with automatic memory function,Can be set for storage10A working mode. Solution dosage(each time)Depending on the reading method used, the peristaltic pump operates at different speeds100/minIn the case of:Each sample4Inhalation in seconds1mLEach reducing agent4Inhalation in seconds0.35mLCarrier liquid4Inhalation in seconds1mL(It can also not be inhaled).

8. High degree of automation: With just one click to start, the entire process of cleaning, sampling, generation, and drainage can be automatically completed.

9. Wide linear range:As（0.5-50ng/mL）；Hg(0.3-100ng/mL)；Se（1-100 ng/mL）；Pb（0.5-80 ng/mL）

10. Strong adaptability: Both new and old models of atomic absorption spectrophotometers at home and abroad can be used,Peak height reading, continuous average integration method reading, and peak area reading (calculation method) can be used. Electric heating or flame heating can be used. Can be used with Zeeman type original suction host.

11. Unrestricted continuous working time: Adopting a two-stage gas-liquid separation device, there is no general generator that needs to stop and clear condensed water accumulated in the gas output pipe, otherwise it can enter the absorption pipe,The disadvantage of splashing onto the lens again does not require the use of desiccants.

12. Light weight and small volume: Net weight approximately6kg,long390mm, Wide215mm, high215mm.

13. Stable quality, low failure rate, easy installation, and convenient maintenance.
