Powder XRD
Instrument Manager: Liana Klivanksy; Alternate: Jian Zhang
The Rigaku Miniflex 6G XRD is a benchtop X-ray diffraction system that can be used to determine phase identification, phase quantification, percent crystallinity, lattice parameter refinement, Rietveld refinement, crystallite size and strain for organic and inorganic crystalline materials. It uses a Cu K alpha radiation with 600W X-ray source at 40 kV voltage and 15 mA current. It can be operated in 0D and 1D modes, covering 2theta range from as low as 2 degrees. The system is equipped with an 8-position sample holder and a high speed D/tex Ultra detector. An Anton Parr BTS500 heating stage is also available for variable temperature experiments.
Single Crystal XRD
Instrument Manager: Jian Zhang; Alternate: Liana Klivansky
The Bruker D8 Venture is a single-crystal X-ray diffractometer to determine the crystal structures of small organic molecules and metal coordination compounds including MOFs. Our D8 Venture will be equipped with two micro focus X-ray sources (Mo and Cu radiation), allowing very small crystals to be measured. The Mo radiation is best for fast high-resolution data collection and for charge density measurements. The Cu radiation is best for determination of absolute structures of light atom compounds. The Oxford Cryostream enables the data collection cooling down at 100 K.
ALS Approved Program for Crystallography
Instrument Manager: Jian Zhang
This approved program provides Foundry users with regular access to ALS chemical crystallography beamline 12.2.1 for single crystal determination of weakly diffracting samples.
Porosimeter (ASAP2020)
Instrument Manager: Liana Klivanksy; Alternate: Jian Zhang
ASAP 2020 and ASAP 2020C are part of the adsorption measurement cluster at the organic facility that are used to measure Brunauer–Emmett–Teller (BET) surface area and porosity of solid materials.
Porosimeter (Tristar)
Instrument Manager: Liana Klivanksy; Alternate: Jian Zhang
Tristar 3020 is also used to measure BET surface area and porosity of solid materials. It is an automated three station analyzer.
Supercritical CO2 Dryer
Instrument Manager: Jian Zhang
The purpose of critical point drying is to dry out a sample without introducing large forces on the structure due to phase boundaries such as surface tension. This is particularly important to the activation of nanoporous materials such as MOFs and COFs. Autosamdri®-931 offers a convenient way to remove the final solvent (usually ethanol) out of the pores and maintain the framework integrity
