Fabrication of a laser-induced fluorescence detector using laser diode was written by He, Chong-hui;Wu, Jing;Wang, Ting-hai;Yang, Hong-qiang. And the article was included in Fenxi Kexue Xuebao in 2015.SDS of cas: 38183-12-9 This article mentions the following:
A laser-induced fluorescence detector was assembled with a com. available low-cost violet laser diode as the excitation source and photomultiplier tube (PMT) as the photoelec. conversion device which were arranged in a confocal optical configuration. Factors including the magnification of objectives, optical filters, current of the laser diode and gain of the PMT, were investigated according to the performance of the detector. Fluorescamine (FA) and fluorescein isothiocyanate (FITC) derived amino acids, rhodamine dyes and fluorescein were used to evaluate the sensitivity of the detector. The limit of detection (LOD) of 0.02 nmol · L-1 was achieved for fluorescamine derived leucine, and LODs for rhodamine B and fluorescein sodium was 9.46 and 1.02 nmol · L-1, resp. Compared with other fluorescence detector, this detector maintains the advantage of low cost, while the sensitivity is much higher and it can also be used for abroad range of dyes for fluorescent labeling. In the experiment, the researchers used many compounds, for example, 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9SDS of cas: 38183-12-9).
4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9) belongs to benzofurans derivatives.Benzofuran is one of the most significant oxygen-containing heterocycles consisting of fused benzene and furan ring, which are widely presented in various naturally occurring and synthetically active compounds. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.SDS of cas: 38183-12-9
