LoFlo Intercomparison

 

Set of three intercomparison cylinders (5 Liters) filled at MPI-BGC with dried natural air to high pressure (200 bars). Four suites of ICP cylinders are circulating between MPI-BGC, LSCE and CSIRO-DMAR where they are measured for CO2 on LoFlo analyzers. LoFlo instruments are based from commercial Licor dual cell NDIR spectrometers. They have been customized by CSIRO-DMAR with very precise gas flow and pressure control to improve the overall performances of the system.

 

Graphs for intercomparison by using all the data and the average difference from MPI reference value are given below. Also a summary file can be found here.
