Solvent bar micro-extraction (SBME) was introduced to improve some aspects of hollow fiber
liquid phase micro-extraction. It has rapidly evolved and gained increasing interest. In SBME …

Solvent bar micro-extraction is a green miniaturized extraction technique that is compatible
with various analytical instruments for trace analysis of analytes in complex matrices. The …

Sample pretreatment is the first and the most important step of an analytical procedure. In
routine analysis, liquid–liquid microextraction (LLE) is the most widely used sample pre …

Developments in the liquid micro-extraction of trace metals from aqueous phases have
proven to be limited when extended from pure water to more complex and demanding …

The use of ionic liquids for micro-extraction of metals has been popularized during the last
decades. The main drawback for this application of ILs is leaching into the sample. Hollow …

Main drawbacks for silver determination in seawater are the effects of samples matrix and
that Ag appears in the sub ng L− 1. Available methods for sample preparation in Ag analysis …

In this work, the reagent Cyanex® 272 has been incorporated in a three-phase solvent bar
micro-extraction system to selectively separate the inorganic and organic fractions of copper …

In this work, trace determination of nitrite in river water samples was studied using solvent
stir bar microextraction system with three-hollow fiber configuration (3HF-SSBME) as a …

Sarcosine is a potential prostate cancer marker. In this study, we developed a method of
three‐phase solvent bar liquid‐phase microextraction combined with high‐performance …

A very simple, sensible and advanced new methodology for the determination of copper
species in seawater has been developed. The method consisted of two steps: first a …
