“…In addition, MLC and VLC are valuable techniques for the direct injection of physiological samples into the chromatographic system since micellar/vesicular mobile phases are capable of maintaining proteins in solution and are swept harmlessly away, eluting with or shortly after the solvent front. In this way, MLC and VLC offer numerous advantages over other LC methods in the bioanalytical field, where they have been extensively used for speciation [15,16,102,103] and drug analysis [99,100].…”

The combination of supramolecular chemistry and MS has not only been fruitful in the field of gas-phase fundamental studies of host-guest complexes and supramolecular assemblies. Mass spectrometric analysis has also benefited from the ability of supramolecular systems to behave as pseudophases in which solutes partition from the bulk solvent phase. Supramolecular systems-based extraction and concentration schemes and separation techniques have been widely used in different fields of analytical chemistry and are ideally suited for coupling with MS. This review describes the present status of the application of supramolecular chemistry in mass spectrometric analysis and includes topics such as the use of coacervative liquid-liquid extraction and hemimicelle/admicelle-based SPE of organic compounds prior to chromatography and electrophoresis. It also discusses the recent advances in enantioselective analysis using CD in electrophoresis- and chromatography-MS. The potential and analytical challenges of these approaches in environmental and bioanalytical chemistry, where one can expect significant developments in the future, are outlined.

ResumoNeste estudo, cromatografia de exclusão por tamanho (SEC) com detecção por UV e detecção off-line por espectrometria de absorção atômica em forno de grafite (GF AAS) foi usada para investigar a associação de cobre a espécies de alta massa molecular (HMW) e baixa massa molecular (LMW) presentes na polpa de açaí (Euterpe oleracea Mart.). A concentração total de cobre obtida nos digeridos da polpa de açaí foi 10,5 µg g -1. Cobre foi encontrado associado às frações de HMW e LMW, correspondentes às massas moleculares de 28,7, 2,6 e 0,43 kDa. PalavRas-chave: metal, SEC, GF AAS, proteínas, Euterpe oleracea Mart. Evaluation of the distribution of copper associated to compounds of different molecular weights in the acai pulp abstRactIn this study, size exclusion chromatography (SEC) with ultraviolet (UV) and graphite furnace atomic absorption spectrometry (GF AAS) off-line detection was used to investigate the association of copper to high molecular weight (HMW) and low molecular weight (LMW) species present in Euterpe oleracea Mart. pulp. Total concentration of copper was 10.5 µg g -1 .Copper was found to be associated to fractions corresponding to 28.7, 2.6 and 0.43 kDa.

“…[8][9][10] Furthermore, because ICPMS can intrinsically be combined with isotope dilution analysis, the species-specific isotope dilution (SSID) analysis has recently been applied to the determination of volatile organometallic compounds, such as Pb, Sn, and Hg. [11][12][13][14][15][16] SSID analysis can compensate for losses during the sample pretreatment and measurement processes once isotopic equilibrium between a spike and an analyte is achieved.…”
