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.
