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)

Applications:

Principal:

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

Technique:

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.
