English term or phrase: quench
Quel est le sens de Quench ici:

The novel automated sampling technology accelerates research and reduces error by immediately quenching reactions for analysis.
x’s new instrument uses proprietary x technology to sample, quench and dilute directly into commercial standard HPLC (high performance liquid chromatography) vials.
Representative samples are immediately quenched, diluted, and transferred to standard HPLC vials on the x.
For example, x could run reactions and automatically take, quench and dilute samples into HPLC vials.

arrêter la réaction pour l'analyse


Explanation:
From my lab experience, quenching means stopping a reaction by cooling with liquid nitrogen. I guess other methods may exist.

Par exemple en français :
Comment arrêter une réaction :

Trempe
Une trempe consiste à refroidir subitement le milieu réactionnel pour ralentir très brutalement, voire arrêter l'évolution du système chimique. Ce processus est d'autant plus efficace que la cinétique de la transformation chimique est fortement dépendante de la température.

soumis à un refroidissement rapide


Explanation:
Par exemple, dans "Representative samples are immediately quenched, diluted, and transferred [...]" : Les échantillons représentatifs sont immédiatement soumis à des étapes de refroidissement rapide et de dilution, puis sont transférés [...]

"L’échantillon est ensuite figé grâce à un refroidissement rapide jusqu’à une température T0 (-150°C) à laquelle la mobilité dipolaire est négligeable."
