ALERT ! AV500 – PROBE SWAP – CHANGE IN SCHEDULE

The original schedule of Probe swap in this instrument has been advanced to today/tomorrow.  Part of the motivation for this is the (good) news that the REVIVED DRX499 is almost ready for full scale deployment within a few days.

We are placing a new probehead called

TBI-1H,13C {X} – Z gradient

in AV500.

  • This probe is a unique Triple Resonance probe. It has :
    • One dedicated channel for 1H – (Tune/Match using two separate knobs)
    • One dedicated¬† channel for 13C – (Tune/Match using two separate knobs)
    • One Broadband channel – the nucleus is selectable via numbers from a directory – similar to the BBI or BBO probe you are familiar with.
  • This is a newer generation probe
    • Excellent B1 homogeneity
    • Excellent 1H sensitivity
  • You don’t have to do any cable swap to observe any of the nuclei.
    • 1H, 13C and X-BB are hardwired.¬† You have to just select the suitable parameter set and observe.

I will post another update by tomorrow afternoon, highlighting more details about this probehead.

Stay tuned.
