Accurate mass measurements are used to both confirm the presence of a compound and help identify unknowns. Furthermore, high-mass accuracy enables the user to generate very narrow extracted ion chromatograms, enabling excellent quantitation. This application note describes the use of the Agilent liquid chromatograph/ mass selective detector time-of-flight (LC/MSD TOF) instrument to identify and...

Labeling of metastatic tumors can aid in their staging and resection of cancer. Near infrared (NIR) dyes have been used in the clinic for tumor labeling. However, there can be a nonspecific uptake of dye by the liver, lungs, and lymph nodes, which hinders detection of metastasis. In order to overcome these problems, we have used two NIR dyes (DyLight 650 and 750) conjugated to a chimeric anti-c...

The use of reactive dyes has increased rapidly due to outstanding properties, growing consumption of cellulosic fibers, and decrease in the production of other application classes of dyes for cellulosics because of cost and health hazards. However, reactive dyes cause the greatest effluent problems for the dye industry. This study explored reusing these dyes in which the residual dyeings were d...

Abstract For the measurement of flow-induced microrotations in flows utilizing depolarization phosphorescence anisotropy, suitable luminophores are crucial. The present work examines dyes xanthene family, namely Rhodamine B, Eosin Y and Erythrosine B. Both solution incorporated particles, examined regarding their luminescent lifetimes quantum yield. In an oxygen-rich environment at room tempera...
