ASTM Methods D2887, D6352, D7169, D7213, and D7500 often are used to characterize petroleum distillates in the boiling range of 174 \u00b0C to 735 \u00b0C, but these analyses present many challenges to refineries and contract laboratories. Both the column construction and the polydimethylsiloxane (PDMS) polymer must be robust enough to withstand the high method temperatures without significant degradation. In addition, columns must yield the proper resolution, exhibit acceptable peak symmetry, and reliably produce accurate boiling point data. Restek\u2019s MXT-1HT SimDist columns are designed to meet these stringent requirements; the robust 1HT SimDist phase is designed for minimum bleed at maximum operating temperatures and the rugged Siltek-treated MXT tubing eliminates breakage, while ensuring column inertness.<\/p>\n\n\n\n<p>While other columns on the market are isothermally tested for performance, only Restek provides application-specific testing for all MXT-1HT SimDist columns. Since each column is individually QC tested using conditions appropriate to the ASTM method for which it is recommended, performance is guaranteed to meet method requirements. Thin film columns (\u22640.21 \u00b5m) are tested using a C18\u2013C80 test mix, while thicker film columns (\u22650.88 \u00b5m) are tested with a C8\u2013C40 test mix. QC acceptance criteria include C50\/C52 or C16\/C18 resolution, bleed, asymmetry (skew), and retention time. Each column you purchase will arrive with a chromatogram similar to the one below\u2014your assurance that the column will perform as required. Increase lab productivity and confidence in your data with an application-tested MXT-1HT SimDist column from Restek.<\/p>\n\n\n\n<p><strong>Every MXT-1HT SimDist column is individually QC tested to ensure performance in the method for which they are recommended!<\/strong><\/p>\n\n\n\n<p><strong>Sample QC chromatogram for cat.# 70112.<\/strong><\/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 wide-image\"><img decoding=\"async\" src=\"https:\/\/ez.restek.com\/images\/cgram\/gc_pc1263.png\" alt=\"Application-Specific QC Test on MXT-1HT SimDist\" title=\"-\"><\/div><p class=\"article-id\" style=\"text-align:center\"> GC_PC1263<\/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>MXT-1HT SimDist, 5 m, 0.53 mm ID, 0.10 \u00b5m (<a target=\"_blank\" href=\"https:\/\/www.restek.com\/p\/70112?utm_source=chromatograms&amp;utm_medium=link&amp;utm_campaign=GC_PC1263\" rel=\"noopener\">cat.# 70112<\/a>)<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Standard\/Sample<\/th><td>Polywax 655<\/td><\/tr>\n<tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Injection<\/th><td>split<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\" colspan=\"2\">Oven<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Oven Temp.:<\/th><td>50 &#176;C to 430 &#176;C at 10 &#176;C\/min (hold 5 min)<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Carrier Gas<\/th><td>He, constant flow<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Flow Rate:<\/th><td>18 mL\/min<\/td><\/tr><\/table><table class=\"conditions col-lg-6 col-12\"><tr><th class=\"conditions_header\" scope=\"row\">Detector<\/th><td>FID @ 430 \u00b0C<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Make-up Gas Flow Rate:<\/th><td>24 mL\/min<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Make-up Gas Type:<\/th><td>N<sub>2<\/sub> <\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Hydrogen flow:<\/th><td>40 mL\/min<\/td><\/tr><tr><th class=\"sub conditions_header\" scope=\"row\">Air flow:<\/th><td>358 mL\/min<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Instrument<\/th><td>Agilent\/HP6890  GC<\/td><\/tr><tr class=\"cgram_header_row\"><th class=\"conditions_header\" scope=\"row\">Notes<\/th><td>Liner cat.# 20994 was used to produce this chromatogram, but it has since been discontinued.
