How do Resonance's Calibration Cells effect Differential Optical Absorption Spectroscopy (DOAS)?
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.
We have comprehensive lines of Spectrometers, Monochromators and Light Sources from Vacuum Ultraviolet (VUV) to Visible (Vis) and we also make custom designed components and systems. If you'd like to speak with us directly please feel free to either give us a call or contact us.
