In-situ O2 Laser Gas Analyzer



Compared to conventional analysis system, our insitu oxygen laser online gas analysis system has the following advantages:



Item

eGAS laser gas analyzer

Conventional online gas analyzer

Pretreatment

Not required

Required

Measurement Method

In Situ,continuous,real time

Discontinuous

Gas Environment

Applicable to adverse environments such as high temperature,high pressure   ,high dust density,high water vapor density,high flow velocity,high   corrosiveness

Only applicable to dry,dust-free gas samples with constant   teperature,pressure and flow velocity

Response Speed

Fast,less than 1 sec

Slow,limited by gas sampling,transport,and instrument electronics   response,20+ sec

Reliability

Average concentration along the optical path,in Situ,real-time;gas   species,dust and gas parameter flutuations

Gas concentration at the tip of the sampling probe only,affected by gas influence,absorption,and leakage during gas sampling and transport ;cross   interferences from other gas species,dust and gas parameter fluctuations



Continuous

Continuous

Discontinuous ;not functioning during back purging

Dependability

No moving parts,high reliable

Quite a lot of moving parts,low reliability

Medium Interruption

No cross interference from background gas species;automatic correction   for dust and optical window contamination

Vulnerable to background gas cross interference ,unable to compensate for   dust and optical window contamination

Calibration & maintenace

Calibration :3-4 times/year

Maintenance:None

Calibration:2-3 times/month

Maintenance:often

Operation Cost

No spare parts ,only electricity

Quite a lot of spare parts,20% of the gas analyzer cost per year
