Abstract
A novel microtube microextraction (MTME) sampling device is proposed in this paper.
The construction of this device is based on a piece of internally coated microtube, closed at one end.
MTME can be easily coupled with gas chromatograph. The standart split/splitless injector, after simple
modernization can be used for the thermal desorption of the analytes from the sorption layer.
Estimation of BTEX in water matrix served as example of the new device applicability.
Proposed device with Tenax-TA as sorbent can provide a stable detection of the simple aromatic
compounds at the level of 0.01 μg/dm3 with RSD (n=5) not more than 9%.
