Integrated Geophysical Analysis and Rock Physics Study to Confirm the Hydrocarbon Reservoir of the Bitrisim Area in Pakistan

Abstract

The matrix effects on analyte vaporization and ICP excitation conditionsin direct sample insertion-inductively coupled plasma atomic emissionspectrometry were studied. Zn was used as a test element and NaCl as thematrix. A slow insertion speed of the sample probe was used to allowpartial separation in time of the vaporization of the volatile Znspecies and the NaCl matrix. Temporal studies of the Zn emissionintensity indicate that ZnCl2 starts to vaporize during sample probeinsertion in the presence of the NaCl matrix. The Zn intensity isreduced because the plume of Zn vapor is not concentrated in the centralchannel of the ICP. Temporal profiles of the intensity ratio of ZnII/ZnIalso shows that introduction of a large quantity of NaCl into the ICPhas little effect on the ICP excitation conditions. The ICP is, however,significantly cooled due to heat loss to the sample probe.
