Thermo Scientific PreCon痕量气体预浓缩装置是专门用于气体样品的前处理装置，可以将少量的气体样品收集并浓缩，大大减少了气体样品的进样量。例如大气中的痕量气体N2O 和CH4，已成为除了CO2之外的重要的温室气体，其含量正在逐年增加，对全球增温效应有深刻影响，而准确地监测这些气体的同位素比值，可以深入地理解它们的来源和分配（即源和汇）。对于大气痕量气体N2O 和CH4 的同位素比值的测定，过去一直受到采样体积和前处理方法的制约，人们通常需要采集和手动处理很大的样品量（例如，需要70升的空气样品才能测定CH4 的13C/12C）。使用Thermo Scientific PreCon 痕量气体预浓缩装置，可以将样品量减少3 个数量级，将样品通量提高至少1 个数量级。
