Continuous vs. segmented second-dimension system gradients for comprehensive two-dimensional liquid chromatography of sugarcane (Saccharum spp.)
(Springer, 2014-07-01)
A comprehensive two-dimensional liquid chromatography system in combination with photodiode array and mass spectrometry detection was developed for analysis of polyphenols in sugarcane (Saccharum spp.) leaf extracts. To ...
Determination of phenolic compounds in strawberries (Fragaria ananassa Duch.) by high performance liquid chromatography with diode array detection
(Springer, 2013-02)
This paper describes a method for simultaneous identification and quantification of phenolic compounds in strawberries followed by a reversed-phase high performance liquid chromatography (HPLC) with diode array detection. ...
SIGNAL-TO-NOISE OPTIMIZATION AND EVALUATION OF A HOME-MADE VISIBLE DIODE-ARRAY SPECTROPHOTOMETER
(Taylor & Francis LtdLondonInglaterra, 1993)
A multichannel photometer based on an array of light emitting diodes for use in multivariate calibration

Development and validation of a High Performance Liquid Chromatography-Diode Array Detection method for the determination of aging markers in tequila
(2008)
A solid-phase extraction procedure followed by analysis by high performance liquid chromatography (HPLC) with UV-vis photodiode array detection (DAD) is proposed to simultaneously determine 11 aging markers in tequila. The ...
Voltammetric behaviour of ketorolac and its HPLC-EC determination in tablets
(Taylor and Francis Inc., 1997)
Ketorolac is an antiinflammatory-analgesic agent that is oxidizable at the glassy carbon electrode. The voltammetric oxidation produces two well resolved pH-dependent peaks, that are overlapped at pH>10. Using this ...
Anthocyanins in berries of Maqui (Aristotelia chilensis (Mol.) Stuntz)
(JOHN WILEY & SONS, 2006-06)
The anthocyanin composition of berries of Maqui [Aristotelia chilensis (Mol.) Stuntz] was deter-mined by HPLC with photodiode array and MS detection. Eight pigments corresponding to the 3-glucosides, 3,5-diglucosides, ...
Photo-thermionic emission and photocurrent dynamics in low crystallinity carbon nanotubes
(2020)
Within this work, it is studied the photo-thermionic and photocurrent behavior of two kinds of carbon nanotube arrays, grown by chemical vapor deposition. One kind is fabricated by using a co-catalyst bilayer approach and ...
