General Information

 

CENTC

The Center for Enabling New Technologies Through Catalysis is a National Science Foundation Phase II Center for Chemical Innovation.  CENTC brings together researchers from across North America to collaboratively address the economic, environmental and national security needs for more efficient, inexpensive and environmentally friendly methods of producing chemicals and fuels from a variety of feedstocks.  Through catalysis, CENTC researchers can lower the energy costs to transforming chemicals, use inexpensive, abundant and nontoxic starting materials and generate less waste.  Through a supplemental research grant, this Elemental Analysis Facility has been established for use by CENTC researchers and other selected scientists.

 

Equipment

Bullet5         Microanalyses are determined on a PerkinElmer 2400 Series II Analyzer.

Bullet5         Sample weights are measured on a PerkinElmer Model AD-6 Autobalance.

Bullet5         Air-sensitive materials are prepared in a dedicated VAC Atmospheres glovebox loaded with Ar (argon) gas, and then crimp-sealed in special tin capsules with a designated die apparatus.

Bullet5         Liquids and volatile solids are also crimp-sealed in special tin capsules with a designated die apparatus.

 

Experiments

Bullet5         The analyzer is calibrated at the beginning of a session.  A calibration standard of known composition is used to determine the correct signal/μg ratio per element.

Bullet5         The calibration is verified prior to and after all sample runs, and at regular intervals during a long series.

Bullet5         Helium carrier gas (99.998 %) is employed:  accuracy is 0.3 % and precision is 0.2 % per element.

Bullet5         All experiments are performed by a single operator, who alone is authorized to use the equipment.

 

Samples

Bullet5         A minimum of 2.0 mg of loose solid or liquid is requested for each determination, but at least twice that amount is recommended.

Bullet5         Air-sensitive samples must be in vessels that will withstand the expansion forces exerted under external vacuum (~0.01 Torr).  Screw cap vials and well-sealed ampules work well.

Bullet5         Samples sent from outside the university are not returned unless prior arrangements are made.

Bullet5         Each sample must have a unique sample name, which will appear on the report.

 

Reports

Bullet5         The submitter receives via email a standard analysis report (PDF).

 

Prices per Determination
