Guidelines
for the Sign-Up and Use of NMR Time
1. Every Thursday
or Friday a sign-up sheet will be posted close to each instrument.
Research groups may use this sheet to reserve NMR time for the following
week.
2. Each research
group is allowed to reserve up to four hours per day during weekdays
on each instrument, during the daytime hours of 9:00 a.m. to 7:00
p.m. Write down the name of your advisor on the sign-up sheet when
reserving NMR time.
3. On weekend
days, the daily reservation limit is increased to six hours per research
group.
4. Each research
group is allowed to reserve two overnight slots (7.00 p.m. to 9:00
a.m.) on any combination of instruments.
5. On Tuesday
of each week, research groups may reserve any number of remaining
overnight slots during that week on any combination of instruments.
6. Research
groups may not reserve the same time slot on all instruments.
7. If an overnight
slot is not reserved as such by 3:00 p.m. of the same day, then hourly
sign- up during the overnight period is allowed with a maximum reservation
during the overnight slot of six hours per instrument. Hourly reservations
during overnight time are not counted as part of the four hour daily
reservation limit.
8. NMR users
may use any spectrometer indefinitely during time when it is not reserved
for use by anyone else (open time). Please be available in person
or by phone if you are using open time (leave a note with your phone
number on the spectrometer).
9. If another
NMR user needs to use the same spectrometer during open time, the
first user is obliged to relinquish the spectrometer no later than
two hours after being given notice that the spectrometer is needed
by another user.
10. NMR users
must sign in the logbook before starting work and sign out of the
logbook after finishing work.
11. NMR users
must start work no later than fifteen minutes after the beginning
of their reserved time, otherwise their entire reservation will revert
to open time.
12. NMR users
may not run over more than ten minutes into another user's reservation.
NMR users who repeatedly inconvenience others by running late and/or
not using their reserved time will be denied use of the NMR facility.
13. If a user
cannot use previously reserved NMR time, the user must cancel the
reservation at least one hour prior to the beginning of the reserved
time, or the user's research group will be charged for the reserved
time.
14. If any user
needs a long block of time ( >22 hours, which is one overnight
plus eight hours), or a block of time longer than the daily reservation
limit during a day, on any instrument, please see Dan so such
needs can be worked into the schedule on an individual basis prior
to the schedule being posted.
15. Please be
aware that there will be times when the NMR staff will need NMR time
for maintenance, training, implementing experiments, service work,
etc. Your consideration with these matters is appreciated.

Important
Policies Regarding NMR Usage
It has become
apparent that there are some policies regarding the use of the NMR
facility which need to be clarified or reiterated. These policies
concern:
1. unauthorized
spectrometer use; i.e., using spectrometers without being checked
out to do so,
2. undocumented
spectrometer usage, and
3. use of substandard
NMR tubes.
Please keep
in mind as you read this that the reason for articulating these policies
is to minimize the instrument downtime that can result from unauthorized
and/or careless use.
1. Unauthorized
spectrometer usage.
POLICY:
every person who wants to use a spectrometer by themselves must be
explicitly authorized to do so by myself or by a NMR Facility Student
Assistant.
This "explicit
authorization" will almost always be some kind of monitored check-out,
in which the person demonstrates to the NMR staff that he/she can
use the spectrometer in question, without assistance from another
person, and without endangering either themselves or the spectrometer.
2. Undocumented
spectrometer usage.
POLICY:
every person who uses a spectrometer must document that usage on the
logsheet.
This must be
done regardless of the length of time the spectrometer was used, or
the time of day it was used, etc. Everyone must be diligent about
documenting spectrometer usage.
3. Use of substandard
NMR tubes.
POLICY:
only Wilmad 507PP or better (e.g.528PP) NMR tubes, or their equivalent,
are approved for use in our NMR Facility.
The "thrift"
NMR tubes that are available from some vendors are not allowed in
any of the NMR Facility spectrometers. In addition, any NMR tube which
does not fit snugly into the spinner turbine is not allowed. I strongly
recommend the use of Wilmad 528PP tubes for the new Bruker Avance
spectrometers and the Bruker AM-400, and Wilmad 507PP (or better)
tubes for use in the Bruker AC-200 and the Varian Mercury-Vx-300.
Note that the use of a substandard NMR tube can damage the NMR spectrometer's
probe. Repair of probe damage resulting from the use of a substandard
NMR tube will be charged to the research group responsible for the
damage.
In summary,
you are expected to remember and adhere to the following policies:
·
Unauthorized use of the spectrometers will result in suspension or
denial of user privileges
·
Undocumented use of the spectrometers will result in suspension of
user privileges
·
Use of substandard NMR tubes in the spectrometers will result in suspension
of user privileges.
