1.2.1 Normal working conditions

(1) Work Environment

Operating Temperature: 15℃ to 30℃

Relative Humidity at Work     ≤75%

(2) Air Path Conditions

Utilizing high-purity argon gas at 99.99% purity, the working gas cylinder pressure is 0.2 MPa to 0.3 MPa, and the instrument is stabilized at 0.2 MPa. The gas line is equipped with an automatic protection device to prevent acidic fluid backflow and corrosion of 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

Main Power Consumption ≤ 400W

Computer Power Consumption ≤ 250W

Printer Power Consumption ≤ 20W

(4) The instrument should be placed on a flat worktable, with an exhaust ventilation system above it. There should be no direct intense light or strong electromagnetic field interference in the vicinity.

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

(6) Preheat Time: 30 mins.
