Lecture 57: Sampling and Analysis of SO2 and NO2 in Ambient Air

[@Filipe.Mobilitex]

Very good class. Could you help me with a question, please? How is the CEMS system calibration process carried out?

[@pavankumar-yv7ev]

Very good video sir on this testing methods but kindly tell how to make calibration curve and calibration standards because without this all procedure is incomplete.

[@brightenvirotech6584]

Good effort & Very informative. At 21th minute, please throw some more light on the volume of air sampled.

[@tamilsciencedigestchannel8456]

very nice class sir it would be helpful for me to know more about so2 anf no2 pollution.

Request to provide the make and model details of impinger box to control temperature of absorbing solutions

[@rajkumarshukla6417]

Very much thank you, Sir.

Hello Sorry for disturbance I Have read your standard 1090 în which are presented Methode for the determination of diferent gases I am interesed about áll gases formula determination For Example 346200 for the Hydrogen 3098 for the carbon monoxide 1039 for the carbon dioxide 2784 for the mercury How these values where determinated ? Thank You in advance for your answers

What should be the flow rate for the ambient air quality (24hr ) monitoring, Weatger it is 1 or 0.2 lpm?

[@ayabass]

1L/min

[@prahalad7826]

0.2lpm is preferred for 24 hr sampling

[@pavankumar-yv7ev]

Kindly tell the how to prepare calibration factor without this all analysis procedure is incomplete

[@AnisurRahman-gp1bu]

How to determination of calibration factor

[@brightenvirotech6584]

plot the graph of Ab vs Conc. Draw a best fit straight line. Determine the slope. CF=1/Slope

Demonstration video need more understanding and clarity
