“…Analogously, silicone membranes can be used to trap and monitor diagnostic gases, VOCs and SVOCs from automobile exhausts , air (Luo et al, 1998) and bioreactors (Matz & Lennemann, 1996). This type of experiment (compare Section VII.B, Preconcentration Methods) can include the individual elements of (i) membrane extraction, (ii) thermal release, (iii) chromatographic separation and, ®nally, (iv) mass spectrometry.…”

“…This type of experiment (compare Section VII.B, Preconcentration Methods) can include the individual elements of (i) membrane extraction, (ii) thermal release, (iii) chromatographic separation and, ®nally, (iv) mass spectrometry. In an interesting application, a polydimethylsiloxane (PDMS) membrane was used to form a membrane introduction/GC/MS instrument for industrial waste water and bioreactor studies (Matz & Lennemann, 1996). The membrane was placed in the bioreactor and used for dissolved gas and VOC analysis and to accumulate SVOCs.…”

“…Commercial bioreactors used for cell and tissue cultures are fairly large (liter to m 3 volumes), and even the term "mini-bioreactor" refers to volumes of 100 ml or so (Marks 2003;Kumar et al 2004). As cells and tissues require constant gas and nutrient flows, it is possible to monitor processes via online analysis (Matz and Lennemann 1996;Luchner et al 2012). Such largescale processes, however, are not amenable to toxicity testing, and so standard AOP-based methods are implemented in microwell arrays (typically 96-well plates) and condensed-phase (liquid) analysis.…”

“…Matz et al 21 propuseram a utilização de TMDA ("Thermal Membrane Desorption Application") como um sistema de amostragem automático para GC-MS, em um processo biotecnológico. A técnica TMDA permite adsorver compostos orgânicos em um polímero e, utilizando um pulso térmico, liberar estes compostos.…”
