HX-201 Atomic Fluorescence SpectrophotometerSelf-developed dual-channel atomic fluorescence products by experts with 20 years of experience in the atomic fluorescence industry, featuring an automatic sampling system. The products offer excellent stability, high sensitivity, low detection limits, small precision, and good repeatability, providing users with a stable, reliable, and quick trace detection device. The gas circuit utilizes imported German flow valves for control, ensuring stable and accurate airflow, eliminating the need for manual adjustment, and effectively reducing argon consumption, thereby lowering long-term operating costs.

Model Description:

HX-201 Model Semi-Automatic Dual-Channel Single-Pump

Application Fields:

Atomic fluorescence spectrophotometers find extensive applications across various fields, including public health and epidemic prevention, food inspection by quarantine departments; water quality testing in urban water supply and drainage systems; environmental sample inspection; clinical body fluids and toxicopathological testing; drug inspection; toxicity testing; geological surveys, and other areas requiring trace element detection for the elements mentioned above. They are capable of performing trace detection on twelve elements, such as arsenic (As), germanium (Ge), selenium (Se), lead (Pb), bismuth (Bi), tellurium (Te), tin (Sn), antimony (Sb), cadmium (Cd), zinc (Zn), and mercury (Hg).

HX-201 Atomic Fluorescence SpectrophotometerTechnical Specifications:

1.2.1 Standard Working Conditions

(1) Workplace Environment

Operating Temperature: 15℃ to 30℃

Relative Humidity at Work     ≤75%

(2) Air Path Conditions

Utilizing a gas source of 99.99%+ high purity argon, the working gas cylinder's secondary pressure is 0.2 MPa to 0.3 MPa, with the instrument stabilizing the pressure at 0.2 MPa. The gas line is equipped with an automatic protection device to prevent acidic fluid from flowing back and corroding the gas line. When the Ar gas pressure drops below 0.15 MPa, the instrument provides an alert, at which point the vapor generation reaction cannot proceed.

(3) Power Requirements

Power Supply: 220V ± 22V

Host Power Consumption ≤ 400W

Computer Power Consumption ≤ 250W

Printer Power Consumption ≤20W

(4) The instrument should be placed on a level workbench, with an exhaust ventilation system above it. There should be no direct strong light or strong electromagnetic field interference nearby.

(5) Instruments should not be placed in environments with strong corrosive (strong acid, strong alkali) gases.

(6) Preheat Time: 30 min.
