Development of an LC-NMR System Using a Diode Array Detector and a Charged Aerosol Detector

Peak Purity Determination with a Diode Array Detector

Peak purity analysis is an evaluation technique for detecting the presence of coeluting impurities in highperformance liquid chromatography (HPLC) data. Running a peak purity check prior to analytical quantitation helps to ensure accuracy. In the development of analytical methods, peak purity analysis can reveal the presence of contamination during standardization and, by doing so, can prevent ...

Callibration of a homemade 4-fold Water Cherenkov Detector array, by detection of EAS events

Enhanced Diode Array Detector Sensitivity and Automated Peak Purity Control

The introduction of the diode array detector helped overcome this problem by providing access to quantitative as well as qualitative spectral information for a wide wavelength range. Agilent Technologie introduced the first diode array detector for liquid chromatography in 1982. Since that time significant improvements in the design of both the hardware and software have been made, Enhanced Dio...

Determination of phosphate using a highly sensitive paired emitter-detector diode photometric flow detector.

The use of a novel inexpensive photometric device, a paired emitter-detector diode (PEDD) has been applied to the colorimetric determination of phosphate using the malachite green spectrophotometric method. The novel miniaturized flow detector applied within this manifold is a highly sensitive, low cost, miniaturized light emitting diode (LED) based detector. The optical flow cell was construct...

A Fast, Robust, Automatic Blink Detector

Introduction “Blink” is defined as closing and opening of the eyes in a small duration of time. In this study, we aimed to introduce a fast, robust, vision-based approach for blink detection. Materials and Methods This approach consists of two steps. In the first step, the subject’s face is localized every second and with the first blink, the system detects the eye’s location and creates an ope...
