The system is designed around a 127 mm mean radius hemispherical analyzer, which is equipped with a triple channeltron detection system for improved sensitivity. By using a magnetic immersion lens, high sensitivity is apparent on small analysis areas. A standard feature is XPS Imaging, which goes down to the 30 um level. The charge neutralization system allows high resolution spectra to be obtained from insulating materials such as polymers using either the standard Mg/Al source or the Al monochromatic source.
The unit has two lasers for exciting fluorochromes: an argon laser, which emits sapphire-colored light at 488 nm, and a red diode laser emitting light at 635 nm. This unit is best suited for the analysis of aqueous suspensions of cells or particles with diameters between 1 and 50 um (microns). Ideally samples should contain 500,000 cells or particles per mL.
When polarized light is passed through a solution containing an optically active compound, the polarized light will rotate clockwise or counter-clockwise. The specific rotation is calculated based on the observed optical rotation by taking into account the cell length and sample concentration.
Research Faculty are sometimes subject to unexpected changes in grant funding due to factors beyond their control and occasionally need time to secure new funding without loss of their employment. The options described below have been developed to meet this challenge of fluctuating funding.
We look back on a successful 2015 and we look forward to new opportunities and challenges in 2016.
Throughout 2015, the University Instrumentation Center (UIC) focused on strengthening its value to the university and the local research community. Some highlights of our major accomplishments in 2015 include:
