Reducing sampling artifacts in active air sampling methodology for remote monitoring and atmospheric fate assessment of cyclic volatile methylsiloxanes
Active sampling methodology for atmospheric monitoring of cyclic volatile methylsiloxanes (cVMS) was improved to reduce sampling artifacts. A new sorbent, ABN Express (ABN), was evaluated for storage stability and measurement accuracy. Storage stability of cVMS on ABN showed less than 1% degradation...

Active sampling methodology for atmospheric monitoring of cyclic volatile methylsiloxanes (cVMS) was improved to reduce sampling artifacts.

Storage stability of cVMS on ABN showed less than 1% degradation of the individual 13 C-labelled octamethylcyclotetrasiloxane ( 13 C 4 -D4), decamethylcyclopentasiloxane ( 13 C 5 -D5) and dodecamethylcyclohexasiloxane ( 13 C 6 -D6) after 14 days storage at room temperature and at −20 °C whereas significant degradation was observed on ENV+ sorbent at room temperature (37–62 %) and −20 °C (9–16 %). 13 C 4 -D4 formed on ENV+ spiked with 13 C 5 -D5, and both 13 C 4 -D4 and 13 C 5 -D5 formed on ENV+ spiked with 13 C 6 -D6.
