application of solid phase microextraction (spme) sampler for determination of carbon disulfide in air
carbon disulfide is used predominantly in the manufacture. it has affects the nervous system. in this study, the applicability of spme as a passive sampler for determination of carbon disulphide in air was studied. effect of sampler and environmental parameters on uptake of carbon disulphide was studied as well. four fibers were tested to select the best sampler for determine carbon disulfide i...

Solid Phase Microextraction (SPME) uses a small volume of sorbent dispersed typically on the surface of small fibres, to isolate and concentrate analytes from sample matrix. After contact with sample, analytes are absorbed or adsorbed by the fibre phase (depending on the nature of the coating) until an equilibrium is reached in the system. The amount of an analyte extracted by the coating at eq...
متن کاملMapping explosive residues on galvanized pipe bomb fragments using total vaporization solid phase microextraction (TV-SPME)
Solid phase microextraction (SPME) is a popular sampling technique whereby analytes are sorbed to a coated fiber and subsequently desorbed into an analytical instrument. In headspace SPME, analytes partition between the sample, the headspace above the sample, and the SPME fiber coating. In total vaporization SPME (TV-SPME), sample extracts are heated until both the solvent and analytes complete...
متن کاملA passive sampler based on solid phase microextraction (SPME) for quantifying hydrophobic
Sediment quality assessment is often hindered by the lack of agreement between chemical and biological lines of evidence. One limitation is that the bulk sediment toxicant concentration, the most widely used chemical parameter, does not always represent the bioavailable concentration, particularly for hydrophobic organic compounds (HOCs) in highly contaminated sediments. In this study, a porewa...
