红外(IR)光谱技术是聚合物识别所用的主要分析手段之一。我们可以提供一系列先进仪器，从Spotlight™ 200i和Spotlight 400红外成像系统，到便携、快速和操作方便的Spectrum Two™红外系统。所有这些系统均配备现成的方法、谱库和独有的Spectrum Touch™软件。研究人员可使用这些仪器对合成聚合物塑胶微粒进行识别和定量，也可用于分析水中的其他化合物-从可见塑料到小于100 µm的微塑料。
确定微塑料颗粒来源的一个重要因素是用于提升聚合物性能的添加剂。常用技术包括热分析或热解与GC/MS相结合的技术，用于聚合物及其有机添加剂（表征颗粒低于100 μm）的高灵敏度分析。ICP-MS分析可用于识别和分析塑料中的无机添加剂。
微塑料颗粒表征的典型应用包括：

Microplastics are a major concern due to their impact on the environment. There is growing research into microplastics, typically submillimeter in size, and which often end up in waterways and oceans. They remain in a suspended state and can be ingested by marine organisms; thereby entering and accu ...
Bottled water is marketed as being the clean and pure alternative to drinking tap water. However, there is increasing opposition to the use of single-use plastic bottles and the fact that they end up in the environment either as intact bottles, or as secondary microplastics when they do break down i ...

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。
Understand the Challenges, Trends & Opportunities of the Polymer Industry. Want to know what the future might look like for plastic manufacturers and recyclers? The whole industry has undergone tremendous change and continues to do so. Manufacturing and recycling are drawing closer, in order to meet ...
Microplastics are tiny plastic particles that form as a result of the plastic content in consumer products and the breakdown of large plastics. Once they have entered the environment, microplastics become pollutant, causing harm to the environment.
