While accurate data on volatile amine content is vital for optimizing the manufacture of compounds from many different classes, GC analysis of volatile amines can be quite challenging due to their basic nature and high polarity. Because of these characteristics, volatile amines will interact with active sites in the analytical column and along the sample pathway, resulting in broad, tailing peaks that are difficult to accurately integrate.<\/p>\n\n\n\n<p>In order to ensure good chromatography for the GC analysis of volatile amines, capillary columns must be highly inert and offer good retention and efficiency. In addition, the GC column phase must be able to withstand tough matrices because volatile amines are often analyzed in the presence of water, alcohol, or ammonia. Base-modified polyethylene glycol columns are sometimes used, but they suffer from relatively poor stability and a loss of efficiency below 60 \u00b0C. Siloxane columns can also be used, as long as relatively pure samples are being analyzed. However, most siloxane columns break down in the presence of harsh matrices, such as water, resulting in short column lifetimes and poor reproducibility. Restek\u2019s Rtx-Volatile Amine column is a better alternative that offers greater stability and improved chromatographic performance for the GC analysis of volatile amines.<\/p>\n\n\n\n<p>The Rtx-Volatile Amine column was designed specifically for analyzing volatile amines in difficult matrices. As shown here, the stable bonded phase yields a column that is not only retentive and highly selective for basic compounds, but is also very robust and able to withstand repeated water injections. Every Rtx-Volatile Amine column is held to stringent quality specifications and QC tested to ensure consistent performance, making Rtx-Volatile Amine columns the best choice for GC analysis of volatile amines.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><\/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 regular-image\"><img decoding=\"async\" src=\"https:\/\/ez.restek.com\/images\/cgram\/gc_pc1237.png\" alt=\"Volatile Amine Test Mix on Rtx-Volatile Amine (60 m x 0.32 mm), Post 600 Water Injections\" title=\"-\"><\/div><p class=\"article-id\" style=\"text-align:center\"> GC_PC1237<\/p><div class=\"chromatogram-peaks\"><h4>Peaks<\/h4><table class=\"peaks col-lg-4 col-12\">\n<thead><tr><th><\/th><th style=\"text-align: left;width: 75px\">Peaks<\/th><th style=\"text-align: center;width: 50px\">t<sub>R<\/sub> (min)<\/th><\/tr><\/thead>\n<tbody><tr><td class=\"num\">1.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for Pyridine\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/110-86-1\/Pyridine\" target=\"_blank\" rel=\"noopener\">Pyridine<\/a><\/td><td class=\"oth\">4.95<\/td><\/tr>\n<tr><td class=\"num\">2.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for 1,2-Butanediol\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/584-03-2\/1,2-Butanediol\" target=\"_blank\" rel=\"noopener\">1,2-Butanediol<\/a><\/td><td class=\"oth\">5.76<\/td><\/tr>\n<tr><td class=\"num\">3.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for Nonane\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/111-84-2\/Nonane\" target=\"_blank\" rel=\"noopener\">Nonane<\/a><\/td><td class=\"oth\">7.62<\/td><\/tr>\n<tr><td class=\"num\">4.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for Diethylenetriamine\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/111-40-0\/Diethylenetriamine\" target=\"_blank\" rel=\"noopener\">Diethylenetriamine<\/a><\/td><td class=\"oth\">11.07<\/td><\/tr>\n<tr><td class=\"num\">5.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for Diethanolamine\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/111-42-2\/Diethanolamine\" target=\"_blank\" rel=\"noopener\">Diethanolamine<\/a><\/td><td class=\"oth\">11.90<\/td><\/tr>\n<tr><td class=\"num\">6.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for 2-Nonanol\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/628-99-9\/2-Nonanol\" target=\"_blank\" rel=\"noopener\">2-Nonanol<\/a><\/td><td class=\"oth\">14.80<\/td><\/tr>\n<tr><td class=\"num\">7.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for 2,6-Dimethylamine\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/87-62-7\/2,6-Dimethylamine\" target=\"_blank\" rel=\"noopener\">2,6-Dimethylamine<\/a><\/td><td class=\"oth\">20.45<\/td><\/tr>\n<tr><td class=\"num\">8.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for Dodecane*\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/112-40-3\/Dodecane\" target=\"_blank\" rel=\"noopener\">Dodecane*<\/a><\/td><td class=\"oth\">22.25<\/td><\/tr>\n<\/tbody><\/table><\/div><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>Rtx-Volatile Amine, 60 m, 0.32 mm ID (<a target=\"_blank\" href=\"https:\/\/www.restek.com\/p\/18078?utm_source=chromatograms&amp;utm_medium=link&amp;utm_campaign=GC_PC1237\" rel=\"noopener\">cat.# 18078<\/a>)<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Standard\/Sample<\/th><td>Volatile amine column test mix (<a target=\"_blank\" href=\"https:\/\/www.restek.com\/p\/35008?utm_source=chromatograms&amp;utm_medium=link&amp;utm_campaign=GC_PC1237\" rel=\"noopener\">cat.# 35008<\/a>)<\/td><\/tr>\n<tr><th class=\"sub conditions_header\" scope=\"row\">Diluent:<\/th><td>Methanol:dichloromethane (50:50)<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Conc.:<\/th><td>900-1,800 \u00b5g\/mL snap and shoot<\/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.
