Abstract
A Teflon-like
coating is the key for the boost in sensitivity of
quartz microbalances for the tracing of airborne analytes. Since the
undesired signals for the interfering compounds are suppressed and
the ones for the targeted compounds (e.g., peroxide explosives) are
enhanced, the PCA output is improved
