Ion Chromatography
(Metrohm – 881 Compact IC pro, website)
Applications: Used for separation of ions and polar molecules in complex reaction mixtures, often coupled with a conductivity detector.
Fluorescence Microscope
(Nikon – Eclipse TE2000-U Inverted Microscope, website)
Applications: Employs a Mercury Arc lamp for excitation and CCD camera for detection. Used for imaging of fluorescent particles, solutions and surfaces, for example measurement of fluorescent microbeads in microfluidic devices.
E. Holcomb et al. Anal. Bioanal. Chem., 2011, 400, 245
Capillary Electrophoresis
(Beckman Coulter – P/Ace MDQ, website)
Applications: Employs a UV detection system and is used for the separation of compounds through application of an electric potential.
D. Noblitt et al, J. Chromatogr. A, 2007, 1154, 1-2, 400-406
Microchip Capillary Electrophoresis
(Homemade)
Applications: Employs a high voltage power supply and is used for separation of compounds in a microfluidic device, through application of an electric potential.
D. Noblitt et al, Anal. Chim. Acta, 2016, 915, 7, 64-73
Flow Injection Analysis
(DropSens – DRP-FLWCL, website)
Applications: Flow injection couples various analytical techniques with a syringe-pumped analyte, for enhance sensitivity and reduce sample volume requirements. In the example above, a wall-jet flow cell is coupled with a screen printed carbon electrode for quantitation of environmental pollutants in aerosol samples.
Potentiostats
(CHI and EDAQ – various models, website, website)
Applications: We have several CHI and EDAQ potentiostats that are employed for electrochemical measurements of environmental and biological analytes, commonly using cyclic voltammetry, electrochemical impedance spectroscopy, chronoamperometry, and stripping voltammetry.
