| Abstract. This is a project to enhance teaching -and student learning- of concepts and procedures of environmental chemistry at the pre-college, freshman, and advanced undergraduate levels at UAF. The project will begin with purchase and installation of an Agilent gas chromatograph-mass spectrometer (GC-MS), model 5895C Inert XL with chemical ionization (CI) and electron impact (EI) sources, and a CombiPal sample injector with headspace and SPME (solid-phase microextraction) capabilities. This instrument will significantly enhance the department's analytical capabilities and will enable faculty to offer a variety of new experiments to students at all levels. | |
| Agilent GC-MS instrument. The machine is installed and working - June 2008. | |

Agilent 5895C Inert XL gas
chromatograph-mass spectrometer (shown with the standard autosampler, which will be replaced by the CombiPal sampling robot seen at the right). |
The CombiPal robot can inject liquid samples, vapors arising from the headspace of an enclosed sample, or a fiber with sample molecules adsorbed to it (a solid phase micro-extraction SPME fiber). |

| Assessment |
| Cindy Fabbri (907-474-1558, ffcf@uaf.edu), from the UAF School of Education, is helping design assessment instruments and write assessment reports for the project. Each proposed experiment has a different specific educational goal. The goals and proposed assessment methods are described in the Project Description (see link below). Also, each of the linked project pages does, or will, have a section detailing assessment plans or results to date. |
