Product catalog summary
Introduction:
The document introduces the AGC Series 100 SED, a gas chromatography system designed for continuous monitoring of nitrogen (N2) in argon (Ar) or helium (He) at parts per billion (ppb) levels. This system is based on the High Frequency Argon Discharge Detector (ADD) technology.

Principal:
The system measures the emission wavelength intensity of nitrogen molecules to determine trace amounts of nitrogen in argon or helium matrix gases. The response is proportional to nitrogen concentration, ranging from low ppb to high parts per million (ppm).

Technique:
The system uses a spectral emission technique with a quartz ionisation chamber. The sample gas is ionised by a high-frequency oscillator, and the nitrogen emission wavelength is detected through a narrow band pass filter and a photomultiplier tube.

Applications:
The AGC Series 100 SED is applicable in various industries, including argon or helium purification plants, the steel industry, air separation plants, welding gas manufacturing, specialty gas manufacturing, doping gas manufacturing, filling stations, the semiconductor industry, chemical plants, and wafer fabs in the electronic industry.

Trace N2 Gas Analysers-1

Series 100 Trace N2 Gas Analyser Analysis of N2 in Argon or in Helium to ppb levels About: The AGC Series 100 SED is engineered for the continuous monitoring of N2 in Ar or N2 in He. Its N2 specific detector has been derived from our extremely successful High Frequency Argon Discharge Detector (ADD) system, the Series 100 HF-ADD Gas Analyser. AGC Instruments has been providing this system configuration for several years to the gas manufacturing companies and especially to argon and helium specific plants throughout the world. Spectral Emission Detector (SED) The emission wavelength intensity of the Nitrogen molecule is selected to determine the trace amount of Nitrogen in Argon or Helium Matrix Gas. The response is proportional to the nitrogen concentration in low ppb to high ppm range. Argon or Helium Purification Plants Steel Industry Air Separation Plants Welding Gas Manufacturing Using a spectral emission technique, a unique quartz ionisation chamber is utilised in which the sample gas is ionised by a high frequency tuned oscillator with the resultant emission wavelength intensity of the nitrogen component is directed through a narrow band pass filter and is detected via a photomultiplier tube.
