AV301 UPDATE : 1H {13C} PROBE WITHOUT VT VARIATION

This old double resonance probe cannot do VT variation.  The lineshape as it exists is usable for the routine runs but needs further optimization.  Since this probe will be treated only as a temporary resource, we are releasing the instrument as it is, to reduce the deficit of dysfunctional instruments to one i.e. AV500.   PLEASE […]

AV500 : UPDATE – DAMAGED HARDWARE

An issue has been identified with the RT shim stack and this makes the instrument unusable currently.  Since repair of this part is not feasible in house, we have to wait for a replacement of the same.   Users will be updated on that front when more information is available.
