摘要： Disclosed are a method and apparatus for accurately measuring nuclear magnetic resonance (NMR) longitudinal axis relaxation time by minimizing the influence of the amount of blood. The method includes applying a first magnetic field MO to a living body portion into which the blood flows magnetizing the blood in a first direction; applying a second magnetic field MZ to at least a portion of the living body portion, to which the first magnetic field MO is applied, magnetizing at least a portion of the blood in a second direction vertical to the first direction;; blocking MZ detecting a signal that is induced as magnetization is returned from the second direction to the first direction; detecting the amount of blood to which the second magnetic field MZ is applied; and calculating the longitudinal axis relaxation time T1 of the blood based on the induced signal and based on the amount of blood.

摘要： A chemical agent analysis system and a method thereof is capable of determining whether or not a sample contains a chemical component of interest. The chemical agent analysis system includes a sample, a first container prepared as a reference of comparison, a second container containing a chemical component which is an object of interest, a differential amplifier for amplifying a difference of IR radiations transmitted through the first and the second containers, and a chemical agent analyzer for collecting IR radiation from a surface of the sample, comparing a difference of the collected IR radiation and the amplified IR radiation from the differential amplifier, and analyzing to determine whether the sample contains the chemical component of interest.
