Abstract

La présente invention concerne un analyseur automatique et un procédé d'analyse d'échantillon. L'analyseur automatique (100) comprend : une unité de remplissage (20) pour remplir un récipient de réaction avec un échantillon et/ou un réactif ; une unité de réaction (10) pour incuber, nettoyer et séparer des réactifs dans le récipient de réaction ; un appareil de mesure (86) pour mesurer un signal de réaction dans le récipient de réaction ; et une unité de transfert (50) pour transférer le récipient de réaction entre différentes positions. L'unité de réaction (10) comporte au moins une position de transfert d'incubation (13a1-3, 13b1-3, et 13c1-3) et au moins une position de transfert de nettoyage et de séparation (13d1-2). L'unité de transfert (50) est apte à transférer le récipient de réaction entre la position de transfert d'incubation (13a1-3, 13b1-3, et 13c1-3) et la position de nettoyage et de séparation (13d1-2). Non seulement une incubation flexible peut être mise en œuvre, mais le problème de l'état de la technique selon lequel de multiples mécanismes de nettoyage et de séparation doivent être mis en œuvre pour réaliser un test en deux étapes est également résolu, et un nettoyage et une séparation efficaces sont entièrement réalisés.
