Presentation Transcript

  1. Setto Septum purge Carrier gas Splitting

  2. Reattivi per derivatizzazione

  3. Reazioni di silanizzazione BSTFA N,O-bis(trimethylsilyl)trifluoroacetamide

  4. Reazioni di acilazione es. pentafluoropropionic anhydride (PFPA)

  5. Analisi quantitativa • Standard esterno • Standard interno • Metodo dell’aggiunta Calcolo fattore di risposta: RF= As x Csi / Asi x Cs As = area o altezza del picco dell’analita da determinare Asi = area o altezza dello standard interno Csi = concentrazione dello standard interno (mg/L) Cs = concentrazione dell’analita da determinare (mg/L)
