The problem with halogenated compounds emissions and its solution

Halogenated compounds contain in their molecular structure an halogen, that is, molecules of chlorine, bromine, fluorine, iodine, etc. Several organic compounds may contain halogens, and thy are dangerous for people and the environment. Some examples of halogenated compounds are methyl chloride (CH3Cl), methyl bromide (CH3Br) and methyl iodide (CH3I). Some of the problems caused by halogenated ...

What is scope 3 emissions accounting?

The Greenhouse Gas (GHG) Protocol categorizes greenhouse gas emissions into three groups or ‘Scopes’. Scope 1 covers direct emissions from owned or controlled sources, while scope 2 ...

Particles as a Part of Air Quality Monitoring

Join us for a 45-minutes webinar that emphasizes the need for particle number (PN) based counting and sizing solutions complimentary to the widely used particle mass (PM) sensors, especially for the size range of ultrafine particles (UFP < 100 ...

Mercury Calibration Source

Mercury calibration lamps are small, rugged, and easy to use. Because the lamps operate at low pressure, well spaced, intrinsically narrow and bright Mercury emission lines dominate the output spectrum. Background between the lines is very low. The output wavelengths are known exactly and are ideal for spectral calibration. Single lines are easily isolated with optical filters for alignment or ...
