d\u00e9sactivation<\/h2>\n\n\n\n<p>Comme les utilisateurs recherchent des limites de d\u00e9tection toujours plus basses, la moindre activit\u00e9 pr\u00e9sente dans l\u2019insert peut provoquer une d\u00e9gradation des analytes et affecter les r\u00e9sultats (tra\u00een\u00e9es de pics, perte de r\u00e9ponse et d\u2019autres probl\u00e8mes que nous avons tous rencontr\u00e9s). En d\u00e9veloppant les inserts d&#8217;injection GC Topaz, Restek a cr\u00e9\u00e9 une nouvelle d\u00e9sactivation, permettant d\u2019obtenir des taux de d\u00e9gradation exceptionnellement faibles.<\/p>\n\n\n\n<p>L\u2019inertie des inserts peut \u00eatre d\u00e9finie comme la r\u00e9duction des interactions entre un insert d&#8217;injection et des compos\u00e9s actifs (et ainsi, une r\u00e9duction de la d\u00e9gradation et de l\u2019adsorption des analytes). La technique de d\u00e9sactivation Topaz consiste \u00e0 passiver simultan\u00e9ment l&#8217;insert et&nbsp; la laine de verre pr\u00e9sente \u00e0 l&#8217;int\u00e9rieur pour qu&#8217;ils soient tr\u00e8s inertes vis-\u00e0-vis d\u2019une grande vari\u00e9t\u00e9 d\u2019analytes r\u00e9actifs. L\u2019inertie am\u00e9liore la sym\u00e9trie des pics et la r\u00e9ponse, et par cons\u00e9quent la quantification, l\u2019exactitude et la pr\u00e9cision des r\u00e9sultats d\u2019analyses.<\/p>\n\n\n\n<p>Les inserts d\u00e9sactiv\u00e9s Topaz permettent d&#8217;\u00e9viter les interactions chimiques ind\u00e9sirables et de r\u00e9duire la d\u00e9gradation au minimum. Ainsi, les donn\u00e9es sont de meilleure qualit\u00e9 et plus fiables, et le &nbsp;l\u2019instrument subit moins de temps d\u2019arr\u00eat. M\u00eame pour l\u2019analyse de faibles concentrations des compos\u00e9s tr\u00e8s sensibles (comme le 2,4-DNP, le carbaryl, l\u2019endrine et le DDT), ces inserts tr\u00e8s inertes donnent des r\u00e9sultats analytiques d\u2019une qualit\u00e9 incroyable.<\/p>\n\n\n<div class=\"wp-block-custom-chromatogram-article-top\"><div class=\"chromatogram-article-placeholder\"><div class=\"figure-heading\"><strong>Figure 1\u00a0<\/strong>: Une grande inertie est importante, surtout avec de la laine.
