The University Instrumentation Center (UIC) recently initiated a project in partnership with the Energy Office, the Sustainability Institute and the College of Life Sciences and Agriculture (COLSA) to evaluate an alternative freezer technology far superior to traditional ultralow freezers.
Kinetic and dynamic studies can be done on nearly all NMR active elements. Both 1-D and 2-D experiments are now offered including: INEPT, DEPT, carbon-carbon coupling detection (INADEQUATE), COSY, NOESY, ROESY, TOCSY, HMQC/HSQC/HMBC, and many others.
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.
The University Instrumentation Center (UIC) has developed a series of instrument recommendations for many common instruments based on experience maintaining instruments across many disciplines for many years. The following is a guide and the UIC staff is available for instrument consulting and recommendations for instruments not listed as well as for specialized applications.
