can any one suggest a new instrument that can collect and/or charectirize nanoparticles, other than SMPS, Nano ID, P-track & HHPC6. thanks
I'm doing an occupational exposure assessment on nanoparticles and I need an instrument that'll give me additional informationa to the ones mentioned above
Hi,
The instruments you have mentioned estimate concentration and/or size of particles. If you need to know additional information about them (composition, structure, morphology etc.) you'll have to collect the nanoparticles from the environment somehow (perhaps there are some kind of filters/separators in those instruments that can be removed?) and analyze them using XRD, S(T)EM etc. Hope this helps! :)

@Dusan, thanks guy :) but that part of the off-line analysis I know, the Nano-Id does exactly that. I wanted something different e.g. something that'll give the surface area or any other criteria in nanoparticles that we sometimes miss when we doing exposure assessments.
A qNano measures liquid borne particles, but has multiple options for measurement. Single particle characterisation. But if you want aerosol information you need a way to transfer airborne particles into liquid.
To determine surface area (and porosity) of your material (if you assume it has porous structure) You can use chemisorption, by e.g. ASAP 2020 instrument from Micromeritics (http://tinyurl.com/75q3kls).
