DOI: 10.1016/j.eimce.2017.04.003

Abstract: Abstract Introduction A variable percentage of samples analysed using the Cobas 4800 assay can give an invalid result by PCR inhibition or erroneous due to incorrect DNA extraction with the Cobas 4800 CT/NG test. Method… read more here.

DOI: 10.1016/j.envpol.2018.01.108

Abstract: Risk assessment of hydrophobic organic contaminants (HOCs) using the total chemical concentration following exhaustive extraction may overestimate the actual availability of HOCs to non-target organisms. Existing methods for estimating HOC bioavailability in soil have various… read more here.

DOI: 10.1016/j.talanta.2022.123442

Abstract: Due to the lack of a correlation with the natural Strontium (Sr) isotopes, it is difficult to apply the isotope dilution (ID) method to an artificial radioactive mononuclide Strontium-90 (90Sr), in inductively coupled plasma-quadrupole mass… read more here.

DOI: 10.1080/01411594.2017.1288230

Abstract: ABSTRACT The synthesis of pinnoite (MgB2O(OH)6) in boron-containing brine was established with a novel dilution method. Effects of temperature, precipitation time, boron concentration and mass dilution ratio on the formation of pinnoite were investigated. The… read more here.

DOI: 10.1080/01932691.2021.1949340

Abstract: An alternative to the conventional dilution method (CDM) to characterize reverse micelles (RMs) containing cosurfactant is presented. This method can be performed following two routes: (i) adding o... read more here.
