VSC-33: Method 3 Orsat Analyzer

VSC-33 Method 3 Orsat Analyzer

VSC-33: Method 3 Orsat Analyzer

Method 3 determines CO2 and O2 concentrations and dry molecular weight of a sample from an effluent gas stream. The gas sample is analyzed for CO2 and O2 on a gas absorption basis, results are expressed in percentage units. For dry molecular weight determination, either an Orsat or a Fyrite analyzer may be used for the calculations.

The Orsat Analyzer Train is designed specifically for Method 3, for analysis of integrated or grab bag samples collected in Tedlar® bags. A liquid filled leveling bottle moves the integrated sample through a graduated glass burette and absorption pipettes containing absorbing reagents. The resulting changes in volume measure percent of O2, CO2 and CO. The burette is water jacketed for temperature stability.

SKU: VSC-33 Category:


The analyzer set-up consists of the following components:

  • The following components are contained in the VersaCase III as shown above using the support brackets.
  • Graduated Glass Burette which is water jacketed for temperature stability.
  • Three glass Absorption Pipettes containing absorbing reagents.
  • The three pipettes are connected to the 3 compartment Tedlar® bag, which is hung behind the pipettes, by way of the valves on the gas expansion bag.
  • A liquid filled Leveling Bottle that is used to move the sample through the Burette and Pipettes.
