Passive sampling as a tool for obtaining reliable analyticalinformation in environmental quality monitoring
PublikacjaSpośród technik pobierania próbek analitów technika dozymetrii pasywnej wydaje się być interesującą alternatywą w stosunku do powszechnie stosowanych technik dynamicznych. Dozymetria pasywna łączy w sobie etap pobierania próbki z etapem izolacji i wzbogacania analitów, które są zatrzymywane w odpowiednim medium zatrzymującym. Prowadzi to do znacznego uproszczenia operacji analitycznych wykonywanych in situ. W odróżnieniu od aktywnych...
