The Method, Hardware and Performance of the PTR3

The PTR3 is a specialized system dedicated to the highly sensitive detection of ultra low traces of volatile organic compounds and their oxidation products that enables monitoring reactions from the first oxidation steps up to highly-oxygenated organic molecules (HOMs) down to ppqV levels (Breitenlechner et al., 2017). The inlet system and the ionization chamber are especially designed to reduce surface interactions. This concept of contact free sampling allows for detecting organics of virtually all volatility classes ranging from volatile (VOC) to extremely low volatile (ELVOC). Recent results from the well-known CLOUD experiment very well illustrate the advantages of the PTR3 over a commonly used nitrate (NO3-) Chemical Ionization Mass Spectrometer (CIMS). Both instruments show a similar detection efficiency towards ELVOCs, but the PTR3 clearly excels the CIMS when it comes to the detection of less oxidized VOCs. https://www.ionicon.com/technologies/details/ptr3

Trident在散热器上的应用

散热器是被动式热交换器，用于将设备产生的热量传递到流动介质中，例如液体冷却剂或空气。 • 散热器是电子和机械设备中热管理的关键

Trident在热界面材料上的应用

导热硅脂、垫片、凝胶等 很多为高分子聚合物基，添加导热填料增加导热系数（石墨烯、氮化硼、陶瓷粉末等） 液体金属导热膏

Trident在导热灌封料上的应用

填充型聚合物通常作为电子产品中的灌封胶，以降低接触热阻并固定电子元器件。灌封胶设计为体或胶状材料，可为电子组件提供结构支撑和物理保护，同时还可置换热量和气体以防止诸如电晕放电之类的现象。 为了提高性能电子设备的散热效果，人们越来需要导热系数更高的灌封料。
