Our Advantage
Wavelength Modulation Spectroscopy(WMS)WMS is a method used to significantly increase the
sensitivity by reducing the low-frequency noise. The laser
light’s intensity is modulated at a high frequency to create a
periodic signal to the detector. The signal is then encoded
and measured at a high frequency, eliminating the effect of
low frequency noise.
Zero BaselineTDLAS technology uses non-absorbing adjacent
wavelengths as a zero point. This is an easier analysis than
detecting a small change in a large signal.
Permanent Wavelength TrackingThe absorption of wavelengths is measured in reference to
two other absorption points to compensate for common
frequency shift. This results in excellent long-term
repeatability to minimize analyzer verifications.
Not resorting to differential measurements means no
switching valves, less hassle disposing of scrubber media,
lower cost of ownership, uncertainty of the CO2, CH
4 and
C2H
4 interferences are zeroed and a much faster respon-
se/reading time.

Teledyne’s 6020L and 8800L series of analyzers leverage the latest in Tunable Diode Laser Spectroscopy (TDLAS) to achieve
ultra-low, fast and reliable analysis of hydrogen sulfide (H2S), carbon dioxide (CO
2) and moisture (H
2Ov). By tuning each laser
to a specific absorption wavelength, based on the gas of interest, the attenuation of the light through a sample cell and the
detector can be correlated to the concentration of each gas, per Beer-Lambert Law.
