Patent ID: 7808242

Claim:
A probe for NMR measurement comprising: a measuring Radio Frequency (RF) coil for measuring a nuclear magnetic resonance (NMR) that sends a high frequency signal at a predetermined resonant frequency to a sample placed in an evenly distributed magnetic field and, at the same time, receives a free induction decay (FID) signal emitted from the sample in response to the high frequency signal that has been sent; a signal line through which the high frequency signal and the FID signal are sent to said measuring RF coil; a stage that holds said measuring RF coil; and a probe container that holds said stage, wherein said measuring RF coil comprises turns and lead lines, said turns comprising a conductive line provided from one end to another end in such a way that the line surrounds a sample tube in which the sample is stored, said lead lines being extended from both ends of said turns, a first capacitor (C 1 ) is connected to an end of a first lead line extended from one end of said turns, a second capacitor (C 2 ) is connected to an end of a second lead line extended from a turn provided between the both ends of said turns, a third capacitor (C 3 ) is connected to an end of a third lead line extended from a turn provided between the both ends of said turns, a position of said turn being different from a position of the turn of said second lead line, a fourth capacitor (C 4 ) is connected to an end of a fourth lead line extended from another end of said turns, another end of each of said first, second, third, and fourth capacitors is grounded, said first lead line and said second line are connected via a fifth capacitor (C 5 ), said third lead line and said fourth line are connected via a sixth capacitor (C 6 ), and a fifth lead line, which is connected between a lead-out point on said turn of said second lead line and a lead-out point on said turn of said third lead line, is connected to said signal line.
