In this rapid analysis of four common fluorotelomer alcohols on the LPGC Rtx-200, excellent separations of all compounds were achieved with a run time of under four minutes (Figure 8). The LPGC method is 1.9x faster and uses 60% less helium than conventional GC-MS methods.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><strong>Figure 8:<\/strong> This analysis of FTOHs on the LPGC Rtx-200 allowed for significant speeds gains while still achieving excellent separation of all isobars.<\/div><div class='chromatogram-article-inner-full'><div class=\"chromatogram-article-inner\">\n<div class=\"wp-block-custom-chromatogram-article\"><div class=\"wp-block-custom-chromatogram-article\"><div class=\"chromatogram-image wide-image\"><img decoding=\"async\" src=\"https:\/\/ez.restek.com\/images\/cgram\/gc_ev1518.png\" alt=\"Fluorotelomer Alcohols on LPGC Rtx-200\" title=\"-\"><\/div><p class=\"article-id\" style=\"text-align:center\"> GC_EV1518<\/p><div class=\"chromatogram-conditions\"><h4>Conditions<\/h4><div class=\"conditions-container container-fluid\"><div class=\"row\"><table class=\"conditions col-lg-6 col-12\"><tr><th class=\"conditions_header\" scope=\"row\">Column<\/th><td>LPGC Rtx-200 column kit, includes 10 m x 0.32 mm ID x 1.00 \u00b5m Rtx-200 analytical column and 5 m x 0.15 mm ID Rxi restrictor factory connected via SilTite connector (<a target=\"_blank\" href=\"https:\/\/www.restek.com\/p\/11807?utm_source=chromatograms&amp;utm_medium=link&amp;utm_campaign=GC_EV1518\" rel=\"noopener\">cat.# 11807<\/a>)<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Standard\/Sample<\/th><td><\/td><\/tr><tr><td><\/td><td>2-(Perfluorobutyl)ethanol<\/td><\/tr><tr><td><\/td><td>2-(Perfluorohexyl)ethanol<\/td><\/tr><tr><td><\/td><td>2-(Perfluorooctyl)ethanol<\/td><\/tr><tr><td><\/td><td>2-(Perfluorodecyl)ethanol<\/td><\/tr>\n<tr><th class=\"sub conditions_header\" scope=\"row\">Diluent:<\/th><td>Methanol (PT)<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Conc.:<\/th><td>1 \u00b5g\/mL<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Injection<\/th><td><\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Inj.
