说明

Application

Potassium hydrogen phthalate may be used as a buffering agent or as a standard for total organic carbon (TOC) calibration and may be used to asses the oxidating activity of CNTs/TiO(2) photoanodes. Potassium hydrogen phthalate solution may be used as a liquid filter to reduce the effects of Rayleigh scattering on collected Raman spectra.

Broadband 308 nm vibrational Raman spectroscopy of gaseous species using a potassium hydrogen phthalate liquid filter and polarization fluorescence suppression.

J E A Saunders et al.

The Review of scientific instruments, 81(1), 013108-013108 (2010-02-02)

Broadband XeCl excimer lasers operating at 308 nm are not currently used in the field of gas phase vibrational Raman spectroscopy (VRS). An explanation as to why alternative wavelengths, and in particular tuneable, narrowband lasers are currently preferred for gas

Phthalates in German daycare centers: occurrence in air and dust and the excretion of their metabolites by children (LUPE 3).

H Fromme et al.

Environment international, 61, 64-72 (2013-10-10)

Phthalates have been used for decades in large quantities, leading to the ubiquitous exposure of the population. In an investigation of 63 German daycare centers, indoor air and dust samples were analyzed for the presence of 10 phthalate diesters. Moreover

Assay of vtg, ERs and PPARs as endpoint for the rapid in vitro screening of the harmful effect of Di-(2-ethylhexyl)-phthalate (DEHP) and phthalic acid (PA) in zebrafish primary hepatocyte cultures.

Francesca Maradonna et al.

Toxicology in vitro : an international journal published in association with BIBRA, 27(1), 84-91 (2012-10-16)

In the last years the concern about the negative effects of phthalates on reproduction significantly increased. Considering that, at date data available dealing with the adverse outcome of Di-(2-ethylhexyl)-phthalate (DEHP) on the reproduction of several species are still contrasting, in
