Instrument - UV to Visible Range Lab Spectroradiometer
Short name:
Spectroradiometer
Full name:
UV to Visible Range Lab Spectroradiometer
What is being measured:
Sampling Protocol:
Online
Manufacturer:
Apogee
Model:
PS-200
Instrument year
:
None specified
Data recording software:
Data analysis software:
SpectraWiz
Raw data time resolution:
Depends on user
Analysis data averaging:
Detection limit:
190 nm - 850 nm
Sensitivity to temperature (and correction method, if applicable):
:
Sensitivity to relative humidity (and correction method, if applicable):
:
RH may affect the spectro-radiometer's sensitivity as far as the water vapors/droplets scatter light. There is no correction done for this as we are actually interested in measuring the effect of RH on UV light transmittance in our chamber.
Sampling method:
Instrument is placed in different areas of interest around the environmental chamber (eg: inside or outside the Teflon bag, close to or away from UV light source, etc.)
Sample preparation method:
Sample residence time (chamber to instrument) (seconds):
Length of tubing (cm):
Instrument flow rate:
Tubing inner diameter:
Tubing material:
Chemical identification method:
Data analysis method:
The detector collects light for the
spectroradiometer via fiber-optic cable.
The spectroradiometer then transmits
its measurements to a PC where custom
software displays the spectrum of
the light source. Live data can be saved as a
data file suitable for work in other programs,
such as Excel.
Quantification method:
Calibration method:
Calibration drift estimate:
No estimate
Calibration schedule:
Uncertainty estimation method:
Uncertainty value provided by manufacturer in instrument manual.
Known interferences:
