Gaseous Products of Incense Coil Combustion Extracted by Passive Solid Phase Microextraction Samplers
Burning incense indoors is a common behavior in Southeast Asia. In this investigation, needle trap samplers (NTS), a novel, green analytical technology is used for sampling gaseous combustion by-products from sandalwood incense coils. To extract indoor volatile organic compounds (VOCs), two NTS are prepared, one using 60–80 mesh and the other using 100–120 mesh divinylbenzene (DVB) particles pa...
متن کاملDetermination of particulate-bound formaldehyde from burning incense by solid phase microextraction.
This work studied the feasibility of using a solid phase microextraction (SPME) fiber for sampling and analysis of gaseous formaldehyde as well as particulate-bound formaldehyde from burning Chinese incense. The SPME fiber with PDMS/DVB coating were partially coated with o-(2,3,4,5,6-pentafluorobenzyl)-hydroxylamine hydrochloride (PFBHA), and used for sampling formaldehyde. The sampling rate fo...
متن کاملSolid Phase Microextraction Analysis of the Gliding Arc Discharge Products
This work was focused on the studies of gliding arc plasma discharge with respect to its use in decomposition of volatile organic compounds and on the solid phase microextraction analysis of the discharge products. The simple one stage gliding arc reactor was used for these experiments. The applied voltage generating the discharge was varied in the range of 3.5 – 4 kV, the dry air and its mixtu...
متن کاملSolid phase microextraction.
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 کاملTheory of solid-phase microextraction
The main objective of this contribution is to describe the fundamental concepts associated with solid-phase microextraction (SPME). Theory provides insight when developing SPME methods and identifies parameters for rigorous control and optimization. A mathematical model has been developed to understand the principal processes of SPME by applying basic fundamental principles of thermodynamics an...
