Electrothermal Vaporisation System Including In Situ Digestion for the Direct Determination of Lead in Botanical Samples by Inductively Coupled Plasma Atomic Emission Spectrometry

The ETV as a thermochemical reactor for ICP-MS sample introduction

“…The advanprocess samples in situ more efficiently than off-line bulk tage of this approach to minimization of space charge matrix processing. An example of this is reported by Okamoto et al,67 interferences is clear, as is extrapolation of the technique to wherein a weighed, powdered botanical sample was mixed the potential speciation of the different electroactive forms with ammonium phosphate (modifier) and placed into an ETV of elements. device.…”

Combining electrothermal vaporization inductively coupled plasma mass spectrometry with in situ TMAH thermochemolysis for the direct determination of trace impurities in a polymer-based photoresist

“…Based on the need to perform in situ digestion, Okamoto et al [21][22][23][24][25][26] reported a furnace-fusion technique that allows the solid samples to be decomposed in situ upon mixing them with various decomposition reagents and then heating the mixtures under a suitable temperature program. In view of the fact that the bulk of the matrix is removed prior to performing the vaporization step, the sensitivity can be improved significantly and interference from the parent matrix can be reduced significantly.…”
