Because of this involvement with cardiovascular disease, many countries require the cholesterol content of food products to be a part of nutritional labels. Much effort is spent on promoting low cholesterol foods and diets and much money is spent on cholesterol-reducing medications [1].<\/p>\n\n\n\n<p>Capillary GC affords qualitative and quantitative analysis of cholesterol and is incorporated into AOAC International methods 970.51E and 976.26.2; According to these methods, cholesterol and other sterols are extracted from the unsaponified fraction of an ether extract of a sample material. The residue is dissolved in chloroform and evaporated (see AOAC methods 933.08 and 970.51A for details [1]). Other methods, including AOAC method 976.26 and AOCS method Ce 3-74 [2,3], describe derivatization of sterols prior to chromatographic analysis.<\/p>\n\n\n\n<p>A highly inert Rxi-5ms capillary column allows qualitative and quantitative analysis of either underivatized or derivatized cholesterol. Figure 1A shows the separation of underivatized cholesterol and internal standard 5-\u03b1-cholestane in less than 9 minutes. The temperature program maximizes separation of the analytes and any early-eluting contaminants or extracted matrix interferences encountered when evaluating complex samples. Figure 1B illustrates a rapid, isothermal method that maximizes throughput when interferences are not a concern.<\/p>\n\n\n\n<p>The same analytical conditions can be applied when analyzing derivatized cholesterol, using the standard extraction and derivatization methods referred to above. Figure 2A and Figure 2B show the chromatographic results. In a series of 9 replicates, using the temperature program, the Rxi-5ms column showed both exceptional inertness and excellent reproducibility for either cholesterol or derivatized cholesterol. Table 1 summarizes the results.<\/p>\n\n\n\n<p>If cholesterol analyses are part of your work regimen, we highly recommend using Rxi-5ms columns to ensure reliable results and increase sample throughput.<\/p>\n\n\n\n<p><strong>Table 1<\/strong>&nbsp;&nbsp;Reproducible results for cholesterol, using an Rxi-5ms column (n=9).<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Analyte<\/strong><\/td><td>&nbsp;<\/td><td><strong>%RSD<\/strong><\/td><\/tr><tr><td colspan=\"3\"><strong>Quantitative Data, Area Count<\/strong><\/td><\/tr><tr><td>cholesterol*<\/td><td>32.5<\/td><td>1.78<\/td><\/tr><tr><td>cholesterol, derivatized**<\/td><td>17.3<\/td><td>1.08<\/td><\/tr><tr><td colspan=\"3\"><strong>Retention Time<\/strong><\/td><\/tr><tr><td>cholesterol*<\/td><td>8.030<\/td><td>0.008<\/td><\/tr><tr><td>cholesterol, derivatized**<\/td><td>8.111<\/td><td>0.044<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>*25\u00b5g\/mL in dimethylformamide.<\/p>\n\n\n\n<p>**50\u00b5g\/mL in hexane.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><strong>Figure 1<\/strong>\u00a0\u00a0Analyze underivatized cholesterol in less than 9 minutes, using an Rxi-5ms column.<\/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_ff00881.png\" alt=\"Underivatized Cholesterol on Rxi-5ms (Temp. program)\" title=\"-\"><\/div><p class=\"article-id\" style=\"text-align:center\"> GC_FF00881<\/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><\/tr><\/thead>\n<tbody><tr><td class=\"num\">1.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for 5-\u03b1-Cholestane (IS)\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/984-87-2\/5-\u03b1-Cholestane\" target=\"_blank\" rel=\"noopener\">5-\u03b1-Cholestane (IS)<\/a><\/td><\/tr>\n<tr><td class=\"num\">2.<\/td><td class=\"cmpd\"><a class=\"cmpd_link\" title=\"View compound information for Cholesterol\" href=\"https:\/\/ez.restek.com\/compound\/view\/en\/57-88-5\/Cholesterol\" target=\"_blank\" rel=\"noopener\">Cholesterol<\/a><\/td><\/tr>\n<\/tbody><\/table><\/div><div class=\"chromatogram-pdf-link\"><a href=\"https:\/\/ez.restek.com\/images\/cgram\/gc_ff00881.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"18\" height=\"18\" viewBox=\"0 0 18 18\"><g data-name=\"Group 2996\"><path data-name=\"Rectangle 1246\" d=\"M0 0h18v18H0z\" style=\"fill: none;\"><\/path><\/g><g data-name=\"Group 2997\"><path data-name=\"Path 729\" d=\"M13.412 11.4v2.017H5.345V11.4H4v2.017a1.349 1.349 0 0 0 1.345 1.345h8.068a1.349 1.349 0 0 0 1.345-1.345V11.4zm-.672-2.694-.948-.948-1.741 1.735V4H8.706v5.493L6.965 7.758l-.948.948 3.361 3.361z\" transform=\"translate(-.437 -.414)\" style=\"fill: rgb(13, 123, 196);\"><\/path><\/g><\/svg>Download PDF<\/a><\/div><\/div><\/div>\n\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_ff00882.png\" alt=\"Underivatized Cholesterol on Rxi-5ms (Isothermal)\" title=\"-\"><\/div><p class=\"article-id\" style=\"text-align:center\"> GC_FF00882<\/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>Rxi -5ms, 15 m, 0.25 mm ID, 0.25 \u00b5m (<a target=\"_blank\" href=\"https:\/\/www.restek.com\/p\/13420?utm_source=chromatograms&amp;utm_medium=link&amp;utm_campaign=GC_FF00882\" rel=\"noopener\">cat.# 13420<\/a>)<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Standard\/Sample<\/th><td><\/td><\/tr><tr><td><\/td><td>1,000 \u03bcg\/mL cholesterol in DMF<\/td><\/tr><tr><td><\/td><td>1,000 \u03bcg\/mL 5-\u03b1-cholestane in hexane<\/td><\/tr><tr><td><\/td><td>25 ng cholesterol, 150 ng 5-\u03b1-cholestane on column<\/td><\/tr>\n<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.
