Title
(EN) THERMAL DESORPTION TUBE SAMPLER
(FR) ÉCHANTILLONNEUR DE TUBE À DÉSORPTION THERMIQUE
Abstract
(EN)
The disclosure provides a thermal desorption (TD) tube sampler. The sampler comprises a first connector configured to reversibly connect to a TD tube containing a sample, and a second connector configured to couple to a direct injection mass spectrometer. The TD tube sampler is configured to desorb a sample in a TD tube connected thereto, and feed the desorbed sample from the TD tube to a direct injection mass spectrometer such that the desorbed sample does not pass through a cold trap.
(FR)
L'invention concerne un échantillonneur de tube à désorption thermique (TD). L'échantillonneur comprend un premier raccord conçu pour se raccorder de manière réversible à un tube TD contenant un échantillon, et un second raccord conçu pour s'accoupler à un spectromètre de masse à injection directe. L'échantillonneur de tube TD est configuré pour désorber un échantillon dans un tube TD raccordé à ce dernier, et pour acheminer l'échantillon désorbé du tube TD vers un spectromètre de masse à injection directe de telle sorte que l'échantillon désorbé ne passe pas par un piège froid.
