For single crystal analysis submit your sample and a fully
completed sample submission form (copies are also available in the lab) to the J.D.
McCullough X-ray Laboratory at 1416 Molecular Science Building. Your sample
will be analyzed on a first come first serve basis. Normal turn around time is
2-3 days. For powder samples no sample submission form is required. Individuals
from other on-campus departments at UCLA must bring a completed form P-39 or
establish a recharge account with the Chemistry Department. Outside users
should mail properly sealed samples to:
Saeed Khan 1412 Molecular Science Building Dept. of Chemistry & Biochemistry University of California at Los Angeles Los Angeles, CA 90095-1569
- Keep crystals in mother liquor.
- Use small vials. If crystals grow in NMR tube, submit the
tube as it is, do not try to remove the crystals.
- Submit more than one vial of crystals, for air
sensitive or unstable compounds.
- Make prior arrangements with the lab director for compounds
which are unstable and degrade quickly. This way we can put you on a priority
list and analyze the compound when the crystals are fresh.
- Verify by some other analysis (NMR, MS, etc) that you are
not submitting a starting material or an unwanted compound. Please note that
few perfect crystals in a mass of trash may not represent the bulk of sample.
