Isopropylammonium formate as a mobile phase modifier for liquid chromatography.
Isopropylammonium formate (IPAF), a new alkylammonium formate (AAF) room temperature ionic liquid, has been synthesized from isopropylamine and formic acid and characterized as an organic solvent mobile phase replacement for reversed-phase liquid chromatography (LC). Characterization of IPAF solvent properties in water such as pH, conductivity, and viscosity, as well as its synthesis, is descri...
متن کاملSuperheated Water Mobile Phases: Liquid Chromatography
Coupled SFE}SFC has shown itself to be a very useful technique for those samples for which it is applicable. The ability to transfer all the extract to the analytical column without manipulation increases sensitivity, reduces contamination and sample handling. The overloading of capillary columns is avoided. Now that methods for using modiRers in the extraction solvent and SFE sample injection ...
متن کاملNormal-phase liquid chromatography of plant hormones using reversed cholic acid micelles as the mobile phase.
When several plant hormones with similar structures are present in a sample, conventional analytical methods are not sufficiently selective to effectively differentiate them. However, the excellent selectivity of micellar liquid chromatography allows similarly structured compounds to be easily differentiated. We used reversed cholic acid micelles dissolved in tetrahydrofuran as the mobile phase...
متن کاملSolid Phase Extraction for 1-Hydroxypyrene as a Biomarker of Occupational Exposure to PAHs Prior to High Performance Liquid Chromatography
Urinary 1-hydroxypyrene is frequently used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons. In this study, solid phase extraction was appropriately conditioned with regard to sample pH, sample concentration, loading flow rate, elution solvent, washing solvent, sample volume and sorbent mass. Octadecyl silica cartridge (C<su...
متن کامل[Determination of four alkaloids in compound Kushen Injection by high performance liquid chromatography with ionic liquid as mobile phase additive].
In order to improve the resolution and peak shape, 1-butyl-3-methylimidazolium tetrafluoroborate ( [ BMIM] BF4 ) was used as mobile phase additive to develop an HPLC method for the determination of four main alkaloids in Compound Kushen Injection. An Agilent TC-C18 column was used with the mobile phase of methanol-0.1% phosphoric acid solution (containing 2. 2 x 10(4) mol/L [BMIM] BF4 ) (5: 95,...
