A micro-flow injection sorbent extraction preconcentration system was combined with a graphite furnace atomic absorption spectrometer. The combination results in an integrated system for the determination of trace amounts of heavy metals. Silica bonded with octadecyl functional groups (C 18 ) was us

The analytical performance of a platinum preconcentration method using a 0.01 M HNO, carrier solution and an alumina microcolumn is discussed. On-line preconcentration is followed by flame atomic absorption spectrometry (FAAS), and off-line preconcentration by graphite furnace atomic absorption spec
Palladium was determined in pharmaceuticals by direct graphite furnace atomic absorption spectrometry (GFAAS) method. The detection limit was 0.1 mg/g in 5% solution; the recovery of 0.5-2.0 mg/g Pd spike was close to 100%. The flow injection GFAAS method was worked out using oxime and iminodiacetic
