List of available equipment
Access to CEMDRX equipment
The equipment of CEMDRX is available to the scientific community, usually on the basis of scientific collaborations with the members of this center, but also on the scope of industrial R&D. Only in the former case the access is free (share of expenses involving cryogenic fluids or gases, chemicals and other consumables may be required. In the case of industrial R&D the cost of access to the equipment wiil be discussed and has to be agreed before the experiment takes place and the signature of a protocol/contract with UC may be required.
To ask for access to the CEMDRX equipment, please send a message to jap@fis.uc.pt.
In the case you intend to use X-ray equipment, please specify the following items:
- Sample composition (elementary formula)
- Type of sample: (single crystal or polycrystal/powder)
- Dimensions of sample(s): linear dimensions (mm) of single crystals; volume (mm^3) of polycrystalline samples
- Issues concerning sample stability: hygroscopy, thermal or photo decomposition; storage conditions required
- Sample availability: specify date when sample will be available
- Dangerous samples: specify possible danger in storage or handling
- Sample environment required for data collection: specify sample temperature in the range 30-300K for single crystals or 80-300K for polycrystaline samples
- Wavelength required (typically Mo or Cu Ka is used, the former for single crystals and the latter for polycrystalline samples)
- Indicate need for determination of absolute configuration in the case of chiral molecules or specify it, if already known
- Proposed schedule for the experiment
- Contact person: (include email and mobile phone)
