A single QCM unit housed within the exposure chamber (side view) [A]; a schematic cross-section of the QCM exposure chamber [B]; and a top view of the chamber base showing that the QCM fits into and replaces the position of one of the three cell support inserts [C2], allowing the remaining two positions to house cell support inserts if required for parallel exposure [C1, 3]. Internal surface area and volume changes upon installation of the single QCM unit were nominal, compared to the original chamber geometry. Crystal ø = 2.5 cm; cell support insert ø = 2.4 cm; crystal’s gold electrode ø = 1.3 cm.
