The airmoHCHO enable the analysis of acetaldehyde and methanol in addition to formaldehyde
Simultaneous on-line monitoring of formaldehyde (HCHO), acetaldehyde and methanol is achieved without interferents.
The new configuration includes a carrier gas back-flush to clean the GC of heavy components in the matrix.
Total cycle time is only 30 min as sample preparation is not required.
They are suitable for ambient air applications with LDL < 4ppb.
These cylinder free solutions include embedded gas generators and calibration at ppb level controlled by GC in rack or wall mounted box.
Results are automatically validated by an internal HCHO permeation tube.
