Instrument Introduction

NCS Testing Technology Co., Ltd. is a high-tech enterprise, which was established by China Iron & Steel Research Institute Group, and it has a strong technical force in production and development.

H-3000 Series Hydrogen Analyzer is a new product, and it is used for hydrogen determination in ferrous and non-ferrous metals, rare earth materials, alloy, and some other inorganic materials. 

Instrument Principle:

Pulse heating inert gas fusion. TCD(Thermal Conductivity Detection).

Related Standard: GBT223.82-2007Technical features:High-resolution thermal conductivity detector is a patented product.patent number:CN101813658Automatic heating power control, closed-loop feedbackHigh sensitive and accurate electric flow control technique based on the low pressure difference is appliedReliable gas path with no dead volumeCarrier gas may use high purity nitrogenCarrier gas saving mode is supportedWarm-up time is shortPrecision reached international advance levelMain performance index

1. Sensitivity:0.001ppm

2. Sample mass:usually 1g

3. Range(1g, sample mass):

Low H:0 - 0.005%*

High H: – 0.1%*

Note:*, range can be changed according to sample mass.

4. Repeatability:

Standardgases: 0.025ppm (0~1ppm)

standard samples: 0.2ppm * or 2% *

Note:*, Measured deviation is not more than standard deviation.

5. Analysis time: about 3 min

6. Pulse heating electrode furnace: Power: Max.8KVA, Temperature: Max.3000°C.

7. Detector:

Anti-oxide NTC thermistor made in US;

Small current control technique is developed to make sure the thermistors can be used without carrier gas;

Keep constant temperature in the whole TCD to make sure the temperature of detected gas to be stable and the results to be accurate.

Reference gas: Low flow control technique is used.

8. Gas flow control: High sensitive and accurate electric flow control technique based on the low pressure difference is applied.

9. Parameters of outgassing, analyzing, flux etc can be setup according to the sample characteristic.

10. Analyzing method with parameters and calibration curve can be established separately according to different samples and can be stored into the database.
