“…These conventional procedures require also the use of large amounts of reagents with resultant negative effects on blank values 7 . Elemental mercury, organo-mercury compounds and mercury complexes are volatile, therefore during sample preparation must be considered [8][9][10][11] . Teflon closed vessels have several advantages compared with open vessels: 1) no acid is lost during the digestion, so that less acid amounts are needed, 2) airborne contamination is eliminated and 3) higher pressures can be used.…”
