The development of new probeheads is an interesting area of research because allows to improve the sensitivity of the NMR spectroscopy and, therefore, expanding the study on samples with limited solubility or of limited availability ( 99CR3133 ).
  • Conventional probeheads are 5mm. Some general features:
  • 1H-detection (inverse) vs X-detection (direct)
  • Specific/selective vs broadband
  • Double Resonance vs Triple-Resonance
  • Pulsed-Field Gradient options: single-axis vs triple-axis
  • Equipped with thermopar and heater
  • Optional automatic Tuning and Matching
  • Microprobes:
  • Micro inverse-detection NMR probes of 3 mm ( 92JMP1343 , 92MRCS66 , 95MRC767 , 95TL6827 , 97MRC614 )
  • Micro-coil NMR probes ( 98AC645 , 99JACS2333 , 99AC4815 , 98JMR227-133 )
  • 1.7mm submicro NMR probes ( 98MRC551 , 99MRC721 , 99MRC527 , 99MRC385 )
  • 2.5mm high-resolution probes to achieve large bandwiths ( 01JMR161-150 )
  • Picoliter 1H NMR (02JMR336-154 )
  • Cryogenic probes
  • Review: 05PROG131
  • 5mm cryoprobe: 99MRC762 , 99MRC512 , 00JACS3554 , 00JACS4823
  • 3mm cryogenic probe ( 00JNP1047 )
  • Probe design for multiple samples (01JMR254-153 and 02JMR97-156 )
    • Cryoprobe Technology
