A Fluorescence Spectrophotometer Recording Corrected Excitation Spectra between 100 degrees K and Room Temperature The method of pressed pellet sample to determine copper,iron,silicon dioxide,calcium oxide and other components in slag and matte was established by using X-ray fluorescence spectrophotometey...
The light emitting diodes were used as excitation light sources, and the emitted fluorescence entered the fluorescence spectrophotometer for signal detection after passing through the lens and a fiber. With high sensitivity, not only the total amount of FWAs in the paper samp...
For a nonfluorescent opaque material, the color appearance depends upon the reflected radiation only in the visible portion of the spectrum, where this radiation is of the same wavelength as the incident radiation. This quantity can be measured on a conventional spectrophotometer in either monochromati...

All solid fluorogens were dissolved in DMSO (Sigma Aldrich, Molecular biology grade, #cat D8418) in 5 mM concentration, and stored in a dark place at −20 °C for no more than 3 months. UV-VIS spectra were recorded on a Varian Cary 100 spectrophotometer. Fluorescence excitation and...
Fluorescence analysis is a fast and sensitive method, and has great potential application in trace detection of environmental toxins. However, many important environmental toxins are non-fluorescent substances, and it is still a challenge to construct a
Ultraviolet absorbance measurements at 254 nm (Abs254) were carried out using a Varian (UV/visible) spectrophotometer with a cell path of 1 cm. The specific ultraviolet absorbance (SUVA) is the ratio of Abs254 and the DOC concentration (Chen et al., 2003b). Ultrapure water (ASTM type I ...
Chloropropanols are common contaminants in food. Recently, food safety issues caused by 3-chloro-1,2-propanediol (3-MCPD) in paper food contact materials (
High throughput screening (HTS) of excipients for proteins in solution can be achieved by several analytical techniques. The screening of stabilizers for proteins adsorbed onto adjuvants, however, may be difficult due to the limited amount of techniques that can measure stability of adsorbed protein ...
