It is known that arsenic demonstrates species-dependent toxicity. Quantification of elemental species in a sample, rather than determining total element levels alone, provides information that can be utilised in assessing toxicity, bioavailability and potential effects on the environment. High performance liquid chromatography (HPLC) coupled with inductively coupled plasma mass spectrometry (ICP-MS)...
Analysis of the pyrethroid Deltamethrin in mint oil was achieved at 10 ng g-1 level by off -line couplil1g liquid chromatography (HPLC) and capillary gas chlomatography (CGC). Both LC and GC conditions are discussed. Mass spectrometry (MS) was used as detection system for the gas chromatographic analysis. The single ion monitoring (SIM) mode was chosen,in order to enha11ce on selectivity and sensitivity...
