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.
特氟龙般的涂层是提高石英微天平对空气中分析物进行追踪的灵敏度的关键。由于抑制了干扰化合物的不期望信号，而增强了目标化合物（例如过氧化物炸药）的信号，因此 PCA 输出得到了改善。
