The aim of the present work is modification standard indophenol blue method in order to be feasible determination ammonium geothermal water samples with high mineral content. Several pretreatment techniques were studied and evaluated neutralise pH all solutions (blank, sample, standards) minimise interferences from salts. Ultrasonic bath followed by mechanical stirring vacuum filtration seems most efficient technique almost 100% recovery . Also there was an optimisation main procedure gain...

A reliable Headspace-Solid Phase Microextraction (HS-SPME) method was developed for the determination of polar volatile components commercial nut-based milk alternative drinks prior to Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Under optimum extraction conditions, a divinylbenzene (DVB)/Carboxen™ CAR)/polydimethylsiloxane (PDMS) fiber used and 2 mL sample heated at 60 °C 40 min under stirring, without salt addition. Ten compounds from different chemical classes (heptane,...

We present a novel sample preparation method for the extraction and preconcentration of volatile organic compounds from whiskey samples prior to their determination by comprehensive two-dimensional gas chromatography (GC × GC) coupled mass spectrometry (MS). Sample compounds, important organoleptic characteristics different whiskeys acceptance liking consumers, is based on use solid-phase microextraction (SPME) Arrow. After optimization, proposed was compared with conventional SPME regarding...

Fabric phase sorptive extraction (FPSE) is a recently introduced sample preparation technique that has attracted substantial interest of the scientific community dealing with bioanalysis. This based on permeable and flexible substrate made fabric, coated sol-gel organic-inorganic sorbent. Among benefits FPSE are its tunable selectivity, adjustable porosity, minimized workflow, substantially reduced organic solvent consumption, rapid kinetics superior efficiency, many which well-known...

The aim of this study was to develop a simple and rapid inductively coupled plasma optical emission spectrometric (ICP-OES) method for the determination 17 metals (Ag, Al, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Tl Zn) in packaged spices. For purpose, spice samples (200 mg) form powder were submitted pressure-assisted wet-acid digestion with mixture 6 mL concentrated HNO3 1 H2O2. proposed validated terms linearity, trueness, precision, limits detection (LODs) quantification...
