Ultraviolet photometer Limas23
Dynamic response
Warm-up time
Approx. 2 hours
90% response time
T
90
≤ 3 sec for measurement cell length = 220 mm, sample
gas flow = 60 l/h and electronic T90 time = 0 sec
Calibration
Zero-point calibration
With inert gas, e.g. N
2
, or with ambient air that is free of the
sample component.
End-point calibration
With gas-filled calibration cells (optional) or with test gases
(for each sample component). It is recommended to verify the
calibration cell set values once a year.
Materials in contact with the sample medium
Analyzer (sample cell)
Tubing: aluminum; windows: CaF
2
; connectors: stainless steel
1.4305 (SAE 303). Option: Tubing, windows and connectors
made of quartz glass.
Gas lines and connectors
Gas lines: FPM hoses; gas connectors: stainless steel 1.4305
(SAE 303)
Gas inlet conditions
The analyzer must not be used for measurement of flammable
gases and ignitable gas/air or gas/oxygen mixtures.
Temperature
The sample gas dew point should be at least 5 °C below the
temperature throughout the sample gas path. Otherwise a
sample gas cooler or condensate trap is required.
The internal temperature of the gas analyzer is at least 10 °C
above ambient temperature.
Inlet pressure
p
e
= 2–500 hPa
Lower pressures require a sample gas pump and higher
pressures require a pressure reducer.
Outlet pressure
Atmospheric pressure
Flow rate
20–100 l/h
Corrosive gases
Highly corrosive associated gas components, e.g. chlorine
(Cl
2
) and hydrogen chloride (HCl), as well as gases or aerosols
containing chlorine must be cooled or undergo prior
absorption.
Gas connections
See page 22
No
te
The gas analyzer cannot be used in combination with the
integral gas feed.
