The metabolic carbon requirements and excretion rates of three major zooplankton groups in the Southern Ocean were studied February 2009. research was conducted framework ATOS project as part Spanish contribution to International Polar Year. objective ascertain possible consequences predicted shift from krill salps for cycling biogenic concentration stoichiometry dissolved inorganic nutrients. respiratory demands NH4-N PO4-P < 5 mm size copepods, estimated by incubation experiments....
Abstract Fluorescent dissolved organic matter (FDOM) in open surface waters (< 200 m) of the Atlantic, Pacific, and Indian oceans was analysed by excitation‐emission matrix (EEM) spectroscopy parallel factor analysis (PARAFAC). A four‐component PARAFAC model fit to EEMs, which included two humic‐ (C1 C2) amino acid‐like (C3 C4) components previously identified ocean waters. Generalized‐additive models (GAMs) were used explore environmental factors that drive global distribution these...
About eight years ago, a new automation approach and flow technique called “Lab-In-Syringe” was proposed. It derived from previous techniques, all based on handling reagent sample solutions in manifold. To date Lab-In-Syringe has evidently gained the interest of researchers many countries, with modifications, operation modes, technical improvements still popping up. proven to be versatile tool for preparation, particularly, liquid-phase microextraction approaches. This article aims assist...
A sensitive and selective automated in-syringe dispersive liquid-liquid microextraction (DLLME) method is presented. It was successfully applied to the determination of aluminum in coastal seawater samples. The complete analytical procedure including sampling, buffering, reaction analyte with fluorescence reagent lumogallion (LMG), extraction, phase separation, quantification completely automized carried out within 4 min. DLLME done using n-hexanol as an extracting solvent ethanol a...
A proof of concept study involving the online coupling automatic dispersive liquid-liquid microextraction (DLLME) to inductively coupled plasma optical emission spectrometry (ICP OES) with direct introduction and analysis organic extract is herein reported for first time. The flow-based analyzer features a lab-in-syringe (LIS) setup an integrated stirring system, Meinhard nebulizer in combination heated single-pass spray chamber, rotary injection valve, used as interface between system...
A robust multichannel manifold involving a multisyringe piston pump used for performing process flow analysis is proposed. The simultaneous sequential determination of two analytes with sampling frequency 97 injections per hour demonstrated. and rapid continuous titration system, including predilution step, was developed. quantitative dilution, avoiding the need diluting standards too, achieved in steps by first splitting concentrated sample stream further dilution mixing chamber. wide range...
