AB  - Several calibration approaches were evaluated for the quantitation of volatile 
      organic compounds in air using miniaturized exhaustive and non-exhaustive 
      sampling techniques, such as in-tube extraction (ITEX) and solid phase 
      microextraction (SPME) Arrow. Eleven compounds, 2-ethyl-hexanol, hexanal, 
      nonanal, toluene, ethyl-benzene, methyl isobutyl ketone, acetophenone, p-cymene, 
      alpha-pinene, trimethylamine and triethylamine, all them found in the natural air 
      samples, were selected as model analytes. Liquid injection, liquid standard 
      addition to the sorbent bed and gas phase standards provided by an automatic 
      permeation system, were evaluated in the case of ITEX packed with laboratory-made 
      10% polyacrylonitrile (PAN) material. Two different approaches, based on sampling 
      of gas phase compounds from the permeation system and from sample vial containing 
      gas phase standards, were evaluated for SPME Arrow with two different coatings, 
      commercial divinylbenzene-poly(dimethylsiloxane) (DVB-PDMS) and laboratory-made 
      mesoporous Mobil Composition of Matter No. 41 (MCM-41). In addition, interface 
      model approach was used for the calculation of the real concentration of the 
      target analytes in the sample from the total amount of analytes injected into the 
      GC-MS in the case of SPME Arrow. Similar results were obtained with the different 
      approaches used for the quantitation by ITEX and SPME Arrow. However, the use of 
      gas phase standards with sample matrix similar to the natural samples, allowed 
      the permeation system to provide the most reliable results for the quantitation 
      of the target analytes. For this approach, linearity (expressed as r(2) values) 
      ranged between 0.991 and 0.999. The limit of detection ranged from 0.5 microg/m(3) 
      (trimethylamine, MCM-41) to 2.2 x 10(-4) microg/m(3) (methyl isobutyl ketone, 
      MCM-41). In addition, the use of the fully automated permeation system provided 
      good reproducibility values that were between 1.4% (acetophenone, MCM-41) and 
      7.8% (methyl isobutyl ketone, 10% PAN). The linear ranges were at least 3 order 
      of magnitude for all the studied analytes with the exception of the calibration 
      curve developed for trimethylamine with SPME Arrow (linear ranges between LOQ and 
      4.9 microg/m(3) (DVB-PDMS) and LOQ and 9.8 microg/m(3) (MCM-41)).
