Emission studies probably reflect one of the broadest ranges of applications for PTR-MS. These studies have in common that they often require a high dynamic range for the detection of VOCs from sub-pptV concentrations up to ppmV levels. PTR-MS easily covers this range! Typical emission studies include:
Reaction kinetics studies
PTR-MS is the ideal analytical equipment to understand the reaction kinetics occurring in the atmosphere. H3O+ mode allows to quantitatively following the photo-chemical decay of parent molecules and the rise of primary products. The even softer A.NH4+ mode is optimal to characterize further oxidized products including esters and peroxides. Reaction kinetics studies include:
Measurements on mobile platforms
PTR-MS is a very robust technology that allows to be deployed in/on mobile platforms. Have a look at the dedicated mobile VOC monitor PTR-TOF QB or contact IONICON for customized mobile solutions. Possible platforms include:
