Up to 3.2 m fixed pathlength in a 100 mL gas cell.

The zephIR © heated integrated FT-IR gas cell is a multipath gas cell.

It is available in fixed pathlengths of 1.2; 2.4; and 3.2 meters (specify at the time of order.)

High sensitivity analysis can be performed allowing for the measurement of sub-ppm* infrared absorbing gases despite the small form factor.

(*) actual levels of detection and sensitivity are a function of the infrared absorptivity of the compound, the pathlength selected, the temperature and pressure at which the measurement is taken, the number of scans co-added (typically 32 to 128) .
