Ioniseringsbuffere
Ionisationsbuffere anvendes til undertrykkelse af fysiske, ioniske og kemiske interferenser ved flammeatomabsorptionsspektroskopi. Disse buffere tilsættes for at øge koncentrationen af frie elektroner i flammens gasser og dermed hæmme og stabilisere graden af ionisation. En hurtig universel kalibreringsmetode blev beskrevet af Schuhknecht og Schinkel, som anbefalede tilsætning af cesiumchlorid og aluminiumnitrat til prøver og standardopløsninger ved flammeemissionsspektroskopisk bestemmelse af natrium, kalium og lithium.
