Fluorotelomer alcohols (FTOHs) have recently emerged as an important class of PFAS compounds in environmental testing laboratories. These compounds are commonly used in manufacturing materials for their oil and water-repellant capabilities but have recently been found to degrade into toxic compounds that pose health and environmental concerns. The degradation products of these volatile FTOHs are frequently detected in indoor and outdoor air samples and thus are important to monitor. Since FTOHs are an emerging class of compounds, testing methodologies are limited. In this application, we developed a rapid analysis of four common fluorotelomer alcohols on the LPGC Rtx-200, achieving excellent separations with a run time of under four minutes. As show in Figure 1, the optimized LPGC method is 1.9x faster and uses 60% less helium than conventional methods. Despite significant speeds gains, excellent separations were still achieved for all isobars.<\/p>\n\n\n\n
Utilizing LPGC for analysis of FTOHs significantly reduces analysis time, improving lab productivity while also conserving helium. Each of our factory-coupled LPGC kits are individually tested, so you can have the assurance of a leak-free connection.
