Les pr\u00e9colonnes sont constitu\u00e9es d\u2019un support et d\u2019une cartouche (et aussi parfois d\u2019un filtre) et s\u2019installent facilement en amont de la colonne analytique afin de la prot\u00e9ger des impuret\u00e9s et particules fortement retenues. Les pr\u00e9colonnes sont comme les colonnes analytiques, mais elles sont plus courtes et destin\u00e9es \u00e0 \u00eatre un consommable \u00e0 dur\u00e9e de vie limit\u00e9e. Choisir correctement sa pr\u00e9colonne LC vous aidera \u00e0 prot\u00e9ger votre colonne analytique et \u00e0 \u00e9conomiser de l\u2019argent en prolongeant sa dur\u00e9e de vie.<\/p>\n\n\n\n<p>Restek propose trois configurations pour ses pr\u00e9colonnes \u2013 EXP, Roc et Trident (connexions directe et en ligne) \u2013 qui sont sp\u00e9cialement con\u00e7ues pour correspondre \u00e0 nos diff\u00e9rentes familles de colonnes LC et\/ou destin\u00e9es \u00e0 une technique sp\u00e9cifique.

Pour une protection contre les particules solides, utilisez un&nbsp;filtre en&nbsp;<strong>ligne UltraLine<\/strong>&nbsp;ou un&nbsp;<strong>simple filtre UltraShield<\/strong>, utilisables tous les deux en UHPLC gr\u00e2ce \u00e0 leur tr\u00e8s faible volume mort.<\/p>\n\n\n\n<p>Une fois le syst\u00e8me de garde choisi, il faut choisir la cartouche adapt\u00e9e \u00e0 la phase stationnaire et aux dimensions de la colonne analytique. Pour ne pas compromettre la s\u00e9lectivit\u00e9 et l\u2019efficacit\u00e9 de la m\u00e9thode analytique, la cartouche de garde doit avoir la m\u00eame chimie que la colonne analytique, c\u2019est-\u00e0-dire, le m\u00eame greffage, la m\u00eame phase stationnaire et la m\u00eame particule. Par exemple, avec une colonne analytique Raptor Biphenyl 2.7\u00b5m, on utilisera une cartouche de garde Raptor Biphenyl 2.7\u00b5m.<\/p>\n\n\n\n<p>Le diam\u00e8tre interne (DI) doit \u00e9galement \u00eatre adapt\u00e9 entre la cartouche de garde et la colonne analytique. Une r\u00e8gle simple est que le DI de la cartouche de garde doit \u00eatre identique ou inf\u00e9rieur au DI de la colonne analytique. On pourra donc utiliser une cartouche de garde de 4.0mm de DI avec des colonnes analytiques de 4.0mm et 4.6mm de DI, et une cartouche de garde de 2.1mm de DI avec des colonnes analytiques de 2.1mm, 3.0mm ou 3.2mm.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u00c9tape 2 : choisir une cartouche de garde compatible avec la colonne analytique<\/h3>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column has-border-color is-layout-flow wp-block-column-is-layout-flow\" style=\"border-color:#ced4d9;border-width:1px;padding-top:10px;padding-right:20px;padding-bottom:10px;padding-left:20px\">\n<p class=\"has-medium-font-size\">Supports EXP<br><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"194\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/figure-article-GNSS2975-02.jpg\" alt=\"\" class=\"wp-image-23278\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/figure-article-GNSS2975-02.jpg 900w, https:\/\/discover.restek.com\/wp-content\/uploads\/figure-article-GNSS2975-02-300x65.jpg 300w, https:\/\/discover.restek.com\/wp-content\/uploads\/figure-article-GNSS2975-02-768x166.jpg 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.restek.com\/global\/fr\/search\/lc-guard-columns\/_\/N-428105918+1698921532?Ns=restekProduct.x_productBadge%7C0\" data-type=\"link\" data-id=\"https:\/\/www.restek.com\/global\/fr\/search\/lc-guard-columns\/_\/N-428105918+1698921532?Ns=restekProduct.x_productBadge%7C0\" target=\"_blank\" rel=\"noopener\"><\/a><a href=\"https:\/\/www.restek.com\/global\/fr\/search\/lc-guard-columns\/_\/N-428105918+1698921532?Ns=restekProduct.x_productBadge%7C0\" target=\"_blank\" rel=\"noopener\">Cartouches Raptor<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.restek.com\/global\/fr\/search\/lc-guard-columns\/_\/N-428105918+2665373166?Ns=restekProduct.x_productBadge%7C0\" data-type=\"link\" data-id=\"https:\/\/www.restek.com\/global\/fr\/search\/lc-guard-columns\/_\/N-428105918+2665373166?Ns=restekProduct.x_productBadge%7C0\" target=\"_blank\" rel=\"noopener\"><\/a><a href=\"https:\/\/www.restek.com\/global\/fr\/search\/lc-guard-columns\/_\/N-428105918+2665373166?Ns=restekProduct.x_productBadge%7C0\" target=\"_blank\" rel=\"noopener\">Cartouches Force<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.restek.com\/global\/fr\/c\/1277?Ns=bestMatch&amp;NttWithIn=UltraShield+UHPLC+PreColumn+Filter\" data-type=\"link\" data-id=\"https:\/\/www.restek.com\/global\/fr\/c\/1277?Ns=bestMatch&amp;NttWithIn=UltraShield+UHPLC+PreColumn+Filter\" target=\"_blank\" rel=\"noopener\"><\/a><a href=\"https:\/\/www.restek.com\/global\/fr\/c\/1277?Ns=bestMatch&amp;NttWithIn=UltraShield+UHPLC+PreColumn+Filter\" target=\"_blank\" rel=\"noopener\">Filtres UltraShield<\/a><\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-medium-font-size\"><strong><strong>Gamme de colonnes LC<\/strong><\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"400\" height=\"142\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/teaser-history-2013-raptor-2.png\" alt=\"\" class=\"wp-image-29554\" style=\"width:385px;height:auto\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/teaser-history-2013-raptor-2.png 400w, https:\/\/discover.restek.com\/wp-content\/uploads\/teaser-history-2013-raptor-2-300x107.png 300w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<tbody style=\"vertical-align: top;\">\n<tr>\n<td><strong>Granulom\u00e9trie<\/strong><\/td>\n<td><strong>Phase stationnaire &#8211;
