It works by trapping the VOC out of the air onto a carbon adsorbent trap at -20 deg C with subsequent desorption at 350 deg C into a helium carrier flow.  This instrument has a time resolution of 1 hour.","keywords":"NCAS","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/617/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/618/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/12928/?format=json"],"instrumentType":"gas_chromatograph","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/2907/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2906/?format=json"]}
