The detector arrangement has an optical cuvette (3) with a wall having a portion transparent for UV radiations, and two UV LEDs (2a, 2b) fixed adjacent to the portion of the wall for emitting the UV radiations with different emission wavelengths in a range of 180-380nm. A wide-band ...
Among the various detectors used in high-performance liquid chromatography (HPLC), the UV detector is frequently referred to as the workhorse, being predominantly employed for quality control purposes and routine analysis. Though characterized by high a sensitivity, a broad linear dynamic range, and ...
Detection of UV light usually occurs via diode array in the range of 190–750 nm [19]. Table 1 shows the UV–Vis cut-off of common cosolvents used in SFC. Even though CO2 has excellent UV transparency [20], the pressure fluctuations that occur as a result of changing the mobile phase...
The 2489 UV/Vis Detector is the most sensitive and versatile dual-wavelength absorbance detector available for HPLC and UHPLC. It is designed to combine a high energy deuterium source, a precise optical design, and low noise, high speed electronics all in one detector. T...
Elements can be classified into three groups: elements with lines that are only sensitive below 165nm such as Cl and Br, elements with lines that are more sensitive than the lines commonly used above 165nm, such as Ga, Ge and In, and elements with lines that can be an efficient ...
Purpose: The authors investigated how the characteristics of the detectors used in a three-stage Compton camera (CC) affect the CC's ability to accurately measure the emission distribution and energy spectrum of prompt gammas (PG) emitted by nuclear de-excitations during proton therapy. The detect...
We designed a waveguide integrated PTE photodetector based on a split-gate geometry similar to the one used in a previous work54,55(Fig.1). Fig. 1: Structure of the realized device. aCross section and top view of the designed PTE graphene photodetector. The active region is the first layer...
The present invention relates to a piezo-electric stretching detector which is used for measuring the positive and negative stretching on the surfaces of rigid structures using electric signals, wherein said detector can be attached by a force connection onto said surfaces in a compressible or non-...
