There are 7 included publications by Dr. Paul Flowers :

TitleDateViewsBrief Description
Easily Constructed Microscale Spectroelectrochemical Cell 2010 903 The design and performance of an easily constructed cell for microscale spectroelectrochemical analysis is described. A cation exchange polymer film, Nafion, was used as a salt bridge to provide ionic contact between a small sample well containing a ...
Easily Constructed Spectroelectrochemical Cell for Batch and Flow Injection Analyses 2002 438 The design and performance of an easily constructed spectroelectrochemical cell suitable for batch and flow injection measurements are described. The cell is fabricated from a commercially available 5 mm quartz cuvet and employs 60 ppi reticulated vi...
Fiber Optic Spectroelectrochemical Sensing for In-Situ Determination of Metal Ions 2007 582 In-situ chemical sensing techniques are increasingly utilized for a variety of applications, including industrial process control, on-site environmental assessment, and detection of explosives and chemical and biological weapons. A common category of...
Incorporating Basic Optical Microscopy in the Instrumental Analysis Laboratory 2011 973 A simple and versatile approach to incorporating basic optical microscopy in the undergraduate instrumental analysis laboratory is described. Attaching a miniature CCD spectrometer to the video port of a standard compound microscope yields a visible ...
Membrane Extraction of Aqueous Transition Metal Ions Using Commercial Nafion Gas Dryers 2004 671 Membrane extraction is a widely employed technique for improving the sensitivity and/or selectivity of a chemical analysis. This paper reports a study on the membrane extraction of aqueous transition metal ions using commercially available Nafion gas...
Small-Scale Production of High-Density Dry Ice: A Variant Combination of Two Classic Demonstrations 2009 50 Easily recoverable, thumb-sized pieces of high-density dry ice are conveniently produced by deposition of carbon dioxide within a test tube submerged in liquid nitrogen. A carbon dioxide-filled balloon sealed over the mouth of the test tube serves as...
Submicroliter Electrochemistry and Spectroelectrochemistry Using Standard Electrodes and a Polymer Electrolyte Salt Bridge. 2013 180 The development of spectroscopic and electrochemical devices that can accommodate very small samples is of considerable importance to many areas of science and technology. We report here on the design and characteristics of a simple apparatus for the...
