LanguageEnglish Pages1-84 LUMiSIzerLSLUMiReader PSALRPSA 4 more psdpsadetermination of the particle size distribution in the range between hundreds of nanometers to hundreds of microns was developed by LUM GmbH. It combines two different approaches and is based on measuring light transmission at three different wavelengthsall along the test tube while sedimentation by gravity occurs (“LUMiReader”). The differences in the transmission of the three different wavelengths allow avoiding the need of applying Mie theory and consequently refractive indexes for the determination of volume weighted particle size distribution. 1554 More details EditionEdited by Marie-Helene Delville and Andreas Taubert LocationWiley-VCH Verlag GmbH & Co.

This study develops a novel approach by using nanoemulsions (NE) for controlled delivery and release of asphaltene inhibitors (AI) to minimize asphaltene precipitation with reduced AI amount. LUMiSizer was utilised to study the effectiveness and performance of controlled release by three cases on asphaltene sedimentation: i) strong organic acids (dodecyl benzene sulfonic acidDBSA)ii) nanoemulsions (blank NEs)and iii) nanoemulsions loaded with DBSA (DBSA NEs).
