“…The analytes present in air samples partition into the SPME coating while being exposed to the fiber. Equilibrium can be achieved by static or dynamic methods, and calibration can be performed using a standard gas generating system or standard gas mixtures [13][14][15][16][17]. In the use of an NTD, the extraction phase (i.e., a sorbent) is packed into a needle with a small hole in its side.…”

“…The GCFID-SPME is a solvent-free sampling and analytic method that has been used recently for sampling organic pollutants in indoor atmospheres and in human blood, urine, and muscle. (Gorlo et al, 1999;Koziel and Pawliszyn, 2001;Waidyanatha et al, 2001) However, the operation procedures and parameters of GCFID-SPME (e.g., the sampling period for adsorbing VOCs, and desorption temperature and time for GC-FID) must be modified by users. The standardized procedures of diffusion adsorption sampling where Q SPME,0 = VOC equilibrium adsorption mass by a SPME fiber under a constant temperature and gaseous VOC concentration; a = kinetic adsorption coefficient between the adsorbate (VOC) and SPME fiber.…”

“…A principal interferência observada nos trabalhos que utilizavam fibras porosas foi a saturação e competição por sítios ativos da fase devido à presença de vários COV na matriz, como mostra o trabalho de amostragem de compostos voláteis de enxofre 44 . Para uma amostragem e análise com boa exatidão, a umidade do local estudado deve ser considerada no processo de quantificação de COV, conforme discutido anteriormente na descrição do processo de absorção 23,24,29 .…”
