La respuesta depende de c\u00f3mo se realizaron las pruebas. El tiempo de retenci\u00f3n pertenece a un m\u00e9todo, as\u00ed como a una muestra.<\/p>\n<h2>\u00bfQu\u00e9 es el tiempo de retenci\u00f3n?<\/h2>\n<p>El tiempo de retenci\u00f3n es el tiempo entre el inicio de la corrida y la aparici\u00f3n de un pico concreto.

Las dimensiones y el material interior pueden diferir. Los componentes pueden interactuar de forma distinta con esos materiales, lo que cambia cu\u00e1nto tiempo permanecen en la columna.<\/p>\n<p>Por lo tanto, dos informes que ambos indican C18 no necesariamente usan el mismo m\u00e9todo.<\/p>\n<h2>El disolvente y el flujo tambi\u00e9n importan<\/h2>\n<p>Muchos m\u00e9todos de p\u00e9ptidos cambian gradualmente la mezcla de disolventes durante una corrida. Esto se llama gradiente. Una mezcla inicial diferente o un cambio m\u00e1s r\u00e1pido pueden desplazar los picos. La velocidad de flujo y la temperatura tambi\u00e9n forman parte de la comparaci\u00f3n.<\/p>\n<p>Lea estos detalles antes de comparar tiempos.

Este trabajo no es una revisi\u00f3n por pares independiente ni un consejo m\u00e9dico.","sameAs":["https:\/\/nhdbio.com"],"url":"https:\/\/nhdbio.com\/es\/author\/qianmiao-technical-team\/"}]}},"_links":{"self":[{"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/posts\/3440","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/comments?post=3440"}],"version-history":[{"count":7,"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/posts\/3440\/revisions"}],"predecessor-version":[{"id":5221,"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/posts\/3440\/revisions\/5221"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/media\/3964"}],"wp:attachment":[{"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/media?parent=3440"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/categories?post=3440"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nhdbio.com\/es\/wp-json\/wp\/v2\/tags?post=3440"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
