\n Stack Emissions Monitoring<\/span>\n <\/h1>\n

\n One of the few laboratories in Argentina with the complete isokinetic\n equipment suite to comply with EPA methods for stack emissions.\n <\/p>\n

\n Biogroup has extensive experience in monitoring stack emissions from industrial\n chimneys of any diameter and height \u2014 applying the \n full suite of US EPA reference methods<\/strong>. Collecting samples from stacks\n is not a simple task: it requires specialised training, isokinetic equipment,\n a clean sample recovery protocol and laboratory capability that few providers\n in the country can offer end-to-end.\n <\/p>\n

\n For dioxins and furans \u2014 the most demanding analysis in stack emissions \u2014 Biogroup\n performs isokinetic sampling in Argentina and analysis is completed at\n Keika Ventures LLC (North Carolina, USA)<\/strong>,\n an associated laboratory with HRGC-HRMS capability per USEPA 1613 and 8290.\n <\/p>\n
