Comme illustr\u00e9 ici, les colonnes Rtx-CLPesticides et Rtx-CLPesticides2 ont une selectivit\u00e9 unique et sont id\u00e9ales pour diff\u00e9rentes m\u00e9thodes analytiques en GC-ECD.<\/p>\n\n\n

REMARQUE : Les analyses d\u2019\u00e9chantillons impurs ou d\u00e9riv\u00e9s peuvent provoquer une contamination de la colonne. Restek ne recommande pas d\u2019analyser les \u00e9chantillons contenant des traces de pesticides \u00e0 la suite d’\u00e9chantillons d\u00e9riv\u00e9s (par exemple, les m\u00e9thodes 8151A et 552.2) sans avoir r\u00e9alis\u00e9 la maintenance de l\u2019injecteur au pr\u00e9alable. Les \u00e9tapes classiques consistent \u00e0 couper l\u2019extr\u00e9mit\u00e9 de la pr\u00e9colonne et \u00e0 changer l\u2019insert d’injection, le joint, le plancher d\u2019injecteur et le septum.<\/p>\n\n\n\n
