1. Scope of analysis

Oxygen: Low oxygen: 0.0001% to 0.5%; High oxygen: 0.5% to 20%

Nitrogen: low nitrogen: 0.0001% to 0.5%; High nitrogen: 0.5% to 50%

Hydrogen: Low hydrogen: 0-0.005%; High hydrogen: 0-0.1%

Note: Changing the sample size can alter the measurement range

2. Analysis accuracy

Oxygen: 0.1ppm or RSD ≤ 1.0%

Nitrogen: 0.1ppm or RSD ≤ 1.0%

Hydrogen: 0.1ppm or RSD ≤ 1.0%

Note: The standard deviation or uncertainty shall not exceed the sample standard deviation.

3. Sensitivity: 0.01ppm

4. Analysis time: usually around 4 minutes

5. Sample weighing: Generally 1g, the sample weight can be adjusted according to the sample content.

6. Pulse furnace: current 0-1500A, power: 7.5KVA, maximum temperature above 3000 ℃. Multiple program heating methods: constant power heating, slope heating. Multiple crucible designs for different sample release situations, in addition to standard crucibles

7. Carrier gas: oxygen nitrogen hydrogen analysis: high-purity helium gas, high-purity argon gas (high-purity argon gas can be replaced for high oxygen samples)

8. Power supply: 220VAC ± 10%, 50/60Hz, maximum current 50A.
