Sample Submission

Samples for X-ray Structure Determination should  be submitted directly to Supervisor of X-ray lab Dr. Arkady Ellern,  room 1711 Gilman Hall . It is always better to inform regarding submission in advance via e-mail ellern@iastate.edu and ask for an appointment. This can prevent unexpected delays and  time overlapping with other customers. The Submission Form has to be filled for EACH SAMPLE. 

Single Crystal Samples:

Samples should be of good optical quality initially and will be evaluated under a microscope to screen their quality. Samples passing the optical test will then be screened by photographic methods and a decision will be made as to weather a successful structure solution could be obtained. See details of X-ray structure determination procedure here

Air stable or solvent sensitive samples can be handled routinely in the laboratory.

Air sensitive samples should be better submitted mounted in a sealed capillary tube. On the other hand, we have some facilities for handling air sensitive crystals. We also have a lot of experience in growing crystals from liquids. Time of submission and possible handling procedures for such non-routine experiments have to be discussed with Supervisor of X-ray Lab Dr. Arkady Ellern well in advance.

Anyone is welcome to have any required consultations regarding growing, handling, submitting and mounting crystals.

Powder Sample Submission

Submitted powder samples should be of a uniform particle size and stable. Thin film samples can be submitted upon consultation with the staff.
The ability to examine air sensitive powders is available upon consultation with the staff.

Data Collection on SMART 1000 CCD diffractometer

Single crystal
data sets for X-ray structure determination by the staff

Authorized users are allowed to collect their own single crystal data . The instrument time has to be reserved in advance. Please, contact Supervisor of X-ray Lab Dr. Arkady Ellern.

Data Collection on Scintag XRD

Powder or thin-film data collection should be  generally done by the user after training.

Data will be collected by the laboratory personnel only on a limited basis by special request. Please, contact  Supervisor of X-ray Lab Dr. Arkady
