When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

Also, the MultiGas' permanently stored, internal calibration spectra eliminates the need for costly calibration gas mixtures. MGS300 is an extractive Continuous Emissions Monitoring (CEM ...
