For laboratories analyzing everything from air quality to flavors and fragrances, thermal desorption offers a faster, easier, more cost-efficient way to prepare samples for GC or GC/MS analysis. Ideal for the trace-level measurement of volatile organic compounds (VOCs)—as well as most semi-volatile chemicals—thermal desorption lets you avoid time-consuming, manual, solvent-based sample preparation in favor of a simple, streamlined, automated approach. It also delivers the added benefits of superior throughput and enhanced sensitivity.
false falseThe coveted and well-recognized “new car smell” is often seen as an indicator of the age and cleanliness of a vehicle. However, what many consumers do not know is that this smell is a result of the off-gassing of volatile organic compounds (VOCs) found in the vehicle’s leather, plastics and textiles ...

C2至C12挥发性有机臭氧前体化合物的分析，是对分析化学家提出的严苛技术挑战。大气中的低浓度，加上需要经常监测以评估日变化，这意味着在通过热解吸分析之前，需要经历样品的预浓缩步骤。虽然样品可以在现场收集并带回实验室，但远程、基于现场的分析可以减少数据周转时间，最大限度地减少样品采集硬件，允许VOCs的存在与否，与气相数据相关。在这一领域中，如对低分子量C2 VOCs进行低温冷却，它们可以被吸附在固体吸附剂上。

本文描述了 PerkinElmer 仪器公司与美国环保局 (US EPA) 合作开发的在野外在线自动监测 C2 到 C12 挥发性有机物而不需要液氮的方法，这套分析系统依靠最新热脱附仪系统支持样品进样，即 TurboMatrix™ TD。
本文建立了检验纵火案件现场燃烧残留物中助燃剂汽油成分的方法。该方法 利用自动热脱附技术对火灾残留物中的助燃剂进行富集、浓缩、脱附后经气-质联用仪( GC-MS) 进行分析，结合现场燃烧环境运用目标化合物法判定是否含有助燃剂汽油成分，简便易行。
本文利用配有在线空气取样附件的TurboMatrix 300 TD 热脱附仪收集、浓缩和脱附各种挥发性有机化合物，再通过配有D-Swafer的Clarus 580 GC分析样品。
本文介绍了一种吹扫捕集技术气相色谱/质谱联用仪 (GC/MS) 方法分析挥发性有机物。通过向样品中鼓入惰性气体，对样品中的挥发性成分进行吹扫。然后在吸附材料上捕集这些成分、加热并反吹到气相色谱仪 (GC) 色谱柱中。使用色谱升温程序分离各分析物，并将其洗脱到质谱仪(MS) 中以用于测定。
文献提供的样品制备方法大致分为三类： 顶空、 溶剂萃取、 水蒸汽蒸馏。 对于GC/MS分析，经典的样品制备方法是顶空或者溶剂提取。
TurboMatrix 650 ATD 系统、 软件以及相应的气相色谱仪(Clarus GC) 能使分析人员快速地装载样品管和设置 TD序列的多重方法， 来测定各种不同类型的样品，它们运行可靠而且不需要用户随后又去输入分流比或者温度变化。
