The purpose of this review is to showcase the present capabilities of ambient sampling and ionisation technologies for the analysis of polymers and polymer additives by mass spectrometry (MS) while simultaneously highlighting their advantages and limitations in a critical fashion. To qualify as an ambient ionisation technique, the method must be able to probe the surface of solid or liquid samples while operating in an open environment, allowing a variety of sample sizes, shapes, and substrate materials to be analysed. The main sections of this review will be guided by the underlying principle governing the desorption/extraction step of the analysis; liquid extraction, laser ablation, or thermal desorption, and the major component investigated, either the polymer itself or exogenous compounds (additives and contaminants) present within or on the polymer substrate. The review will conclude by summarising some of the challenges these technologies still face and possible directions that would further enhance the utility of ambient ionisation mass spectrometry as a tool for polymer analysis.
本次综述旨在展示当前用于通过质谱法（MS）分析聚合物和聚合物添加剂的环境采样和离子化技术的现有能力，同时批判性地突出它们的优点和局限性。要成为一种环境离子化技术，该方法必须能够在开放环境中探测固体或液体样品的表面，允许分析各种不同大小、形状和基底材料的样品。本综述的主要部分将遵循分析过程中解吸/提取步骤的基本原理进行指导；液体提取、激光烧蚀或热解吸，以及主要研究的成分，无论是聚合物本身还是存在于聚合物基底内部或表面的外源化合物（添加剂和污染物）。综述将通过总结这些技术仍然面临的一些挑战以及可能进一步增强环境离子化质谱作为聚合物分析工具的效用的方向来结束。
