Why is an IONICON PTR-MS very well suited for your measurement tasks?

PTR-MS is a very strong technique to explore the organic composition of air, fluids and even solid samples.  In our lab we developed different thermal desorption applications including the characterization of organic aerosol and detection of nanoplastics in snow.
