Large scale analysis of protein conformational transitions from aqueous to non-aqueous media
(BioMed Central, 2018-01)
Background: Biocatalysis in organic solvents is nowadays a common practice with a large potential in Biotechnology. Several studies report that proteins which are co-crystallized or soaked in organic solvents preserve their ...
Separation of four isomeric tropane alkaloids from Schizanthus grahamiii by non-aqueous capillary electrophoresis
(2005)
The potential of non-aqueous capillary electrophoresis was investigated for the separation of four isomeric tropane alkaloids, namely 3α-senecioyloxy-7β-hydroxytropane, 3α-hydroxy-7β-senecioyloxytropane, 3α-hydroxy-7β-an ...
Non-aqueous Titration of Gatifloxacin in Pharmaceutical Formulations using Perchloric Acid
(2003-10-01)
An inexpensive, simple, precise and rapid method for the determination of fluoroquinolone gatifloxacin in tablets is described. The procedure is based on the use of volumetric dosage in a non-aqueous medium in glacial ...

Non-aqueous electrolytes for isotachophoresis of weak bases and its application to the comprehensive preconcentration of the 20 proteinogenic amino acids in column-coupling ITP/CE-MS
(Springer Heidelberg, 2014-11)
Isotachophoresis (ITP) has long been used alone but also as a preconcentration technique for capillary electrophoresis (CE). Unfortunately, up to now, its application is restricted to relatively strong acids and bases as ...
Use of the aqueous biphasic system as an alternative for concentration of Ascaris lumbricoides eggs, with non-toxic separation of faecal residues and fats
(Wiley-Blackwell, 2019-11-01)
Objectives Human enteroparasites are considered a serious public health problem in underdeveloped countries located in world regions with tropical, subtropical and equatorial climates. These parasites are commonly diagnosed ...
