The chemistry of samples analyzed using gel permeation chromatography/size-exclusion chromatography/gel filtration chromatography (GPC/SEC/GFC) is very diverse. Different chemistries of stationary phases are required to allow for true size separation. Several types of materials are available, all of which have their advantages and limitations. While silica‑based stationary phases are most common in high performance liquid chromatography (HPLC), for macromolecules polymer-based phases are popular.

PCDDs, PCDFs, and PCBs are toxic compounds categorized as POPs and are ubiquitous throughout the world. Detecting trace levels of PCDD and PCDF is important to monitor food supplies and to ensure industrial emissions meet regulatory standards. In line with the ongoing innovation in dioxin analysis technology, the US EPA is currently evaluating a new method-APGC–MS/MS-for PCDD and PCDF confirmatory analysis. Joe Romano and Douglas Stevens from Waters Corporation discuss the benefits of this new method.
