Abstract
This work reports the development of a fast and reliable amperometric sensor for the detection of amino acids. The detector was constructed using copper nanoparticles (CuNPs) supported on reduced graphene oxide (RGO) modified glassy carbon electrode (CuNPs-RGO/GCE) and based on the application of high performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD). Under optimized isocratic HPAEC-PAD conditions (using 40 mmol L-1 NaOH as mobile phase, flow rate of 0.30 mL min-1 and detection potential of 0.45 V vs. Pd/PdO), the linear dynamic ranges of the concentration of amino acids obtained were 0.50-50 µmol L-1 for lysine, 1.0-100 µmol L-1 for alanine, glycine and serine, and 5.0-100 µmol L-1 for leucine. The limits of detection (S/N = 3) obtained ranged from 0.10 (for lysine and leucine) to 0.50 µmol L-1 (for alanine, glycine and serine) and sensitivity varied from 6.1 (for leucine) to 21.5 nA µmol-1 L (for serine). The average recovery percentages ranged from 97% (for glycine) to 102% (for leucine and serine). The results obtained showed that the CuNPs-RGO/GCE has good long-term stability, repeatability and reproducibility; this makes the device suitable for application as an electrochemical detector. The successful application of the proposed method for the analysis of sugarcane vinasse demonstrates its suitability for separation and determination of amino acids in complex matrices.

Abstract
The combined use of a dual-UV detector as well as a fluorimetric and a multielectrode electrochemical detector (equipped with a dual electrode, consisting of a conventional size 3 mm diameter glassy carbon electrode (GCE) and of a pair of 30 μm thick carbon microfibers) is proposed for the detection of the following 15 underivatized amino acids: L-histidine (His), L-cysteine (Cys), creatine (Crn), S-methyl-L-cysteine (Me-Cys), DL-homocysteine (Hcy), L-methionine (Met), beta-(3,4-dihydroxyphenyl)-L-alanine (DOPA), L-tyrosine (Tyr), DL-m-tyrosine (m-Tyr), L-a-methyl-DOPA (Me-DOPA), L-phenylalanine (Phe), DL-alpha-methyltyrosine (Me-Tyr), 5-hydroxy-tryptophan (5-HTP), 3-nitro-L-tyrosine (NO2Tyr), and L-tryptophan (Trp), as well as of 2 dipeptides L-cystathionine (Cysta) and L-carnosine (Car), and of creatinine (Cre). A multilinear solvent (acetonitrile) gradient elution program, determined by a simple optimization algorithm, is required for the efficient reversed-phase separation of the above mixture of 18 solutes within 27 min at a flow rate of 1.0 mL/min and at 25 °C.

Abstract
A simple and sensitive method was developed for simultaneous determination of methotrexate (MTX) and folic acid (FA) by ion chromatography with electrochemical detection (IC-ECD). Quaternary amine functionalized multi-wall carbon nanotubes (q-MWNTs) modified glassy carbon electrode (GCE) was used as an amperometric sensor to determine MTX and FA. The electrochemical behaviors of MTX and FA at the q-MWNTs/GCE were studied by cyclic voltammetry (CV). Results indicated that this modified electrode exhibited electrocatalytic oxidation toward MTX and FA with high sensitivity, stability and long life. Good separation of MTX and FA was demonstrated by IC on an anion-exchange column with phosphate buffer solution (PBS) as eluent. Under the optimal conditions, the linear ranges were from 0.01 to 20mg/L for both MTX and FA with correlation coefficients r ≥ 0.9994. The obtained detection limits (LODs) for MTX and FA were 0.2 and 0.4 μg/L (S/N=3), respectively. The method has been successfully applied to the determination of MTX and FA in plasma and urine of patients of rheumatoid arthritis.

Abstract
This paper presents a new LC method with evaporative light scattering detection (ELSD), for the separation and determination of the biogenic amines (histamine, spermidine, spermine, tyramine, putrescine and β-phenylethylamine) which are commonly present in cheese, as their presence and relative amounts give useful information about freshness, level of maturing, quality of storage and cheese authentication. The LC-ELSD method is validated by comparison of the results with those obtained through LC-UV determination, based on a pre-column dansyl chloride derivatisation step. The obtained data demonstrate that both methods can be interchangeably used for biogenic amines determination in cheese. The new LC-ELSD method shows good precision and permits to achieve, for standard solutions, limit of detection (LOD) values ranging from 1.4 to 3.6 mg L(-1) and limit of quantitation (LOQ) values ranging from 3.6 to 9.3 mg L(-1). The whole methodology, comprehensive of the homogenization-extraction process and LC-ELSD analysis, has been applied in the analysis of a typical Calabria (Southern Italy) POD cheese, known as Caciocavallo Silano. The most aboundant amine found was histamine, followed, in decreasing order, by tyramine, spermine, putrescine, β-phenylethylamine and spermidine, for a total amount of 127 mg kg(-1). This value does not represent a possible risk for consumer health, according to the toxicity levels reported in literature and regarded as acceptable.

Abstract
The paper presents a new HPLC method, hyphenated with mass spectrometry detection, for the separation and determination of the biogenic amines that are most commonly present in cheese, namely cadaverine, histamine, spermidine, spermine, tyramine and tryptamine. The HPLC-MS/MS method is validated by comparison of the results with those obtained through a literature HPLC-UV determination, based on a pre-column dansyl chloride derivatisation step. The intercalibration is based on the statistical t-test for multiple samples that allows to compare simultaneously the results obtained with the two methods for more analytes and to decide, at a prefixed confidence level, if the two methods are inter-changeable. The new HPLC-MS/MS method, employed in selected reaction monitoring (SRM) mode, permits to achieve for standard solutions limit of detection (LOD) values ranging from 1.7 to 22.5 microg L(-1) and LOQ (limit of quantitation) values ranging from 5.6 to 68.2 microg L(-1). In order to apply the method in the analysis of cheeses, LOD and LOQ values have also been evaluated in "ricotta" cheese, in order to take as possible into account the matrix interference. In these conditions LODs range between 5.1 and 35.0 microg L(-1) and LOQs between 14.2 and 101.2 microg L(-1). The whole methodology, comprehensive of the homogenization-extraction process and HPLC-MS/MS analysis, has been applied in the analysis of three typical Piedmont (North-West Italy) cheeses, known as Toma Piemontese, Raschera and Castelmagno.

Abstract
Electrochemical methods for the detection of amino acids, peptides, and proteins in a variety of media are reviewed. Label-free strategies in which the detection is based on the inherent electrochemical properties of the analyte are discussed. Various processes such as direct or mediated (in solution or immobilised) redox processes and interfacial ion transfers have been employed for the electrochemical detection and determination of the target analytes. The various methods covered encompass voltammetry at uncoated and modified electrodes and at immiscible liquid-liquid interfaces, potentiometry at polymer membrane electrodes and electrochemical impedance spectroscopy. The determination of the target analytes in complex biological matrices is discussed. The various approaches highlighted here illustrate the rich capabilities of electrochemical methods as simple, low-cost, sensitive tools for the determination of these important biological analytes at trace and ultra-trace levels.

Abstract
This study compares the main commercial detectors that can detect amino acids in their underivatized form. The detectors tested are: the chemiluminescent nitrogen detector (CLND), the evaporative light scattering detector (ELSD), the nuclear magnetic resonance spectrometer, conductivity detector, refractive index, UV, and electrospray quadrupole mass spectrometry (in simple and tandem MS mode). As ELSD, CLND and MS require a volatile mobile phase, an ion-pair reversed-phase liquid chromatographic system was selected, consisting of an octadecyl column and an aqueous mobile phase containing pentadecafluorooctanoic acid as volatile ion-pairing reagent. Underivatized taurine, hypotaurine, aspartic acid, hydroxyproline, asparagine, serine, glycine, glutamine, cysteine, glutamic acid, threonine and alanine were simultaneously analysed with each detector. In order to test the applicability of these detectors to "real world" samples, the amino acid stoichiometry of the tetrapeptide Gly-Gly-Asp-Ala was determined with each detector after acid hydrolysis. The detectors were compared in terms of linearity, limit of detection, advantages and disadvantages as well as special features (capacity to provide structural information, specificity, quantification with single calibration curve, etc.).

Abstract
The problems associated with attempting to apply voltammetric techniques to the analysis of biologically relevant organics within complex media are identified and, through reviewing the very recent literature (1999-mid-2001), possible solutions are described. The boundaries of the search were limited to research targeted at the resolution of specific problems, associated with quantitative determinations. Various strategies have emerged to counter problems of poor sensitivity and selectivity and these have been summarized and critically appraised. Where possible, the characteristics of each approach have been distilled into a table format to ease comparison. Emphasis has been placed on the collation of information that will improve the intrinsic electrode response and as such should be of value to those interested in pursuing electroanalytical methodologies regardless of context.

Abstract
Simultaneous chiral separations of underivatized amino acids have been performed using a teicoplanin-based chiral stationary phase and ionspray tandem mass spectrometry for their ionisation and detection. Different amino acid enantiomer pairs were separated simultaneously, including those of positional isomeric amino acids (e.g., L,D-Leu/Ile, or L,D-Val/Iva). Due to the specificity of tandem mass spectrometry, co-eluting enantiomers of different amino acids could also be determined. Fifteen chiral underivatized proteinogenic and non-proteinogenic amino acids were analysed simultaneously under isocratic conditions (acetonitrile-water, 75:25) in less than 25 min. For maximum sensitivity, post-column addition of 500 mM aqueous HCOOH was necessary. Detection limits varied from 2.5 to 50 microg l(-1) depending on the amino acid. The signal vs. concentration relationship was linear for all D- and L-amino acids (0.9995 < or = r2 < or = 1) for three orders of magnitude.
