Determination of trace metals in polymers by flameless atomic absorption with a solid sampling technique

Sampling and sample preparation

“…By the early and mid seventies, the exclusive use of Teflon, polyethylene and synthetic quartz were established to be the materials of choice for sample containment [37,38,65,96,107,131]. In 1968, Robertson [ 1081 produces an impressive amount of data for 10 trace elements in a wide variety of container materials and structural materials.…”

Determination of trace metals in fresh water mussels by atomic absorption spectrometry with direct solid sample injection

“…In a batch mode, control of the interferences is of paramount importance if a suitable calibration is to be made. For some directly inserted solids, aqueous standards have proved adequate (10,11), but this is not generally the case. It is perhaps the inherent difficulty in accurately synthesizing the sample matrix in the laboratory and the consequent uncertainty in calibration that has kept the method of direct solid insertion from widespread use.…”
