Title (EN) APPARATUS AND METHODS FOR DETERMINING PROPERTIES OF LIQUID-BEARING SOLIDS USING NUCLEAR MAGNETIC RESONANCE
(FR) APPAREIL ET PROCÉDÉS PERMETTANT DE DÉTERMINER DES PROPRIÉTÉS DE SOLIDES CONTENANT UN LIQUIDE À L'AIDE DE LA RÉSONANCE MAGNÉTIQUE NUCLÉAIRE
Abstract:
(EN) Nuclear magnetic resonance (NMR) methods and apparatus are provided for investigating a sample utilizing NMR pulse sequences having solid state and CPMG pulse sequence portions. Various embodiments of solid state pulse sequences may be utilized including two-dimensional (repetitive) line-narrowing sequences. The hydrogen content of a solid portion of the sample may be determined by using one or more echoes resulting from the solid state sequence portion of the pulse sequence to establish a total organic hydrogen content of the sample, and by using a CPMG echo train to establish a fluid organic hydrogen content, and by subtracting one from the other to obtain the hydrogen content of the sample's solid portion. Additionally, or alternatively, the T2 values obtained from the line-narrowing and CPMG pulse sequences can be compared by plotting to obtain information regarding a characteristic of sample. NMR pulse sequence may also include T1 portion.
(FR) L'invention concerne des procédés et un appareil de résonance magnétique nucléaire (RMN) permettant d'examiner un échantillon à l'aide de séquences d'impulsions RMN ayant des parties de séquence d'impulsions à l'état solide et CPMG. Divers modes de réalisation de séquences d'impulsions à l'état solide peuvent être utilisés, notamment des séquences de restriction de ligne (répétitives) bidimensionnelles. La teneur en hydrogène d'une partie solide de l'échantillon peut être déterminée en utilisant un ou plusieurs échos résultant de la partie de séquence à l'état solide de la séquence d'impulsions pour établir une teneur totale en hydrogène organique de l'échantillon, et en utilisant un train d'échos CPMG pour établir une teneur en hydrogène organique fluide, et en soustrayant l'un de l'autre pour obtenir la teneur en hydrogène de la partie solide de l'échantillon. En outre, ou en variante, les valeurs T 2 obtenues des séquence de restriction de ligne et d'impulsion CPMG peuvent être comparées par traçage pour obtenir des informations concernant une caractéristique de l'échantillon. La séquence d'impulsions RMN peut également comprendre une partie T 1 .
