Calibration Cells

Calibration Cells

Differential Optical Absorption Spectroscopy (DOAS) is a technique used to measure trace quantities of a target species of gas by measuring their optical absorption of a broadband source and, by using both the broadband and narrowband absorption cross-section against a reference spectrum, determining its concentration.

Resonance Ltd. supplies a line of DOAS calibration cells filled with a variety of gases. These cells can be filled to concentrations ranging from 0 -2000 ppm-m and are designed to fit most standard DOAS systems.  Made with quartz or Pyrex, these cells can withstand the harshest environments and are extremely resistant to scratches and contamination, providing a long and reliable lifetime.
