| 摘要 |
<p>The present invention discloses both methods and apparatus for carrying out proton magnetic resonance thermal analysis (PMRTA) measurements in which the non-equilibrium transient NMR response is measured with acceptable time resolution whilst the sample is subjected to a specified temperature regime. The technique is applicable to many materials including coal and polymers. The automation of a known manually operable limited temperature range NMR spectrometer to provide a PMRTA having a high temperature capability is disclosed. A probe (105) suitable for holding the sample and having an RF coil (109) and heater (107) is also disclosed.</p> |
