Sample Submission

For single crystal analysis submit your sample and a fully completed sample submission form (copies 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

It is advisable to:

• 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.
