Using Passive FT-IR Remote Sensing Measurements
Fourier transform infrared (FT-IR) spectroscopy has been used to identify unknown materials, determine the quality or consistency of a sample, and determine the amount of components in a mixture. Gary Small, of the Department of Chemistry and Optical Science and Technology Center at the University of Iowa, spoke to Spectroscopy about his work using passive FT-IR remote sensing measurements.

A Rapid FT-IR-based Method for Monitoring Detergent Removal from Biological Samples
Here we report a novel infrared-based method that permits fast and impartial analysis of detergent removal from biological samples. Because this method is spectrally based and label-free, determination of protein concentration can be performed simultaneously. An additional benefit of this technique is the small volume (2 µL) required for analysis, a significant fact given the often precious nature of biological samples. MORE » |

Development of an Ultrasensitive LC–MS-MS Method for Determination of 5-Fluorouracil in Mouse Plasma
5-Fluorouracil (5-FU) is a low-molecular-weight anticancer drug in clinical use for several solid tumors in humans. Currently, the most widely used methodology for 5-FU quantitation is liquid chromatography–tandem mass spectrometry (LC–MS-MS) with either liquid–liquid extraction (LLE), protein precipitation, or a combination of both as sample cleanup procedures.
