“…Another spectroscopic technique such as nuclear magnetic resonance (NMR) has been used for the rapid analysis of oil and fact content in agrifood products [45], or in the mode 31P NMR to solve different problems in food analysis [46]. Other topics currently under development are the application of chemiluminescence in food analysis [47] or the use of chemiluminescence as detection in LC [48] or CE [49]. Other spectroscopic techniques like fluorescence [50] or modern electrothermal atomic absorption spectrometry have also found interesting applications in food analysis [51].…”

This paper presents a revision on the instrumental analytical techniques and methods used in food analysis together with their main applications in food science research. The present paper includes a brief historical perspective on food analysis, together with a deep revision on the current state of the art of modern analytical instruments, methodologies, and applications in food analysis with a special emphasis on the works published on this topic in the last three years (2009)(2010)(2011). The article also discusses the present and future challenges in food analysis, the application of "omics" in food analysis (including epigenomics, genomics, transcriptomics, proteomics, and metabolomics), and provides an overview on the new discipline of Foodomics.

“…Compared to other analytical techniques [5] CL possesses significant advantages such as simplicity, low cost and high sensitivity and selectivity [5]. Consequently, CL-based detection has become considered as a quite useful and interesting technique for scientists in a wide variety of disciplines [29][30][31]. But in spite of great advantages of CLbased detection system, this technique has been still limited because of limitations such as low selectivity; small sensitivity and/or less improved detection limit [5].…”

A new method has been introduced based on aerosol hygroscopic growth as a new factor for trace and ultra-trace determination of phosphorous in flame containing optical trapping-cavity ring down aerosol extinction (emission) spectrometer (OT-CRD-AES). In this study, a cavity ring down has been designed using hydrogen and air as fuel and oxidant during introduction of the aerosols containing phosphorous species using an ultrasonic generator (humidifier) from an acidic solution by a flow rate of N 2 , followed by detection of the Mie scattering using a charged coupling device (CCD) system. Parameters having strong influence during following scattering of the aerosols during their hygroscopic growth inside the humidified flame (H 2 /air), include: influence and amount of Na + as radiation buffer (as light source), flow rates of H 2 , air and N 2 , kind and concentrations of acid, evaluation of the aerosols inside flame, etc. These parameters were optimized using simplex and one at a time methods. Based on the figures of merit under optimized condition, two linear calibration curves with reverse slopes were evaluated between 10.0 -250.0 ng mL -1 and 1.0 -20.0 µg mL -1 with correlation coefficients (R 2 ) the same as 0.999 and 0.998, respectively. The calibration sensitivities were also estimated to 57.46 and 0.348 (a.u), respectively, with detection limit of 5.0 ng mL -1 . The mechanism of the radiation (Mie scattering) was also evidenced based on i) dependency of the scattered radiations to the quantity of an alkali ions such as Na+ as well as the humidity, ii) presence of acceptable correlation between the response of the cavity with turbidometry, iii) observation of blue shift from green (color related to the luminescence of HPO* in H 2 /air flame) to blue (scattered radiation) and finally iv) effect of hydration number during stability and growth of the aerosols inside the flames.No serious interference was evaluated during analysis of at least 500-fold excess of various foreign species. However, the only observed interference was evaluated during introduction of 200-fold excess of SO 4 2-. Good correlation was also evaluated between the results obtained from this technique and ion exchange chromatography during analysis of wastewater samples that clearly revealed the reliability of this method for phosphorous detection and determination at µg mL -1 and ng mL -1 levels.

“…[19][20][21] Here, we report on a new CLIA for PCT that uses N-(aminobutyl)-N-(ethylisoluminol) (ABEI) as the luminescence substrate and magnetic particles that serve as both the solid phase and the separator in a liquid phase, offering many more active binding sites than a tube wall. Two different monoclonal antibodies are labeled with either ABEI or fluorescent-5-isothiocyanate (FITC).…”

Our objective is to develop an assay based on magnetic particles (MPs) to determine the concentration of procalcitonin (PCT) using a chemiluminescence immunoassay (CLIA). Fluorescein isothiocyanate (FITC) and N-(aminobutyl)-N-(ethylisoluminol) (ABEI) were used to label two different anti-procalcitonin (PCT) monoclonal antibodies. The labeled antibodies, the PCT antigen, and the anti-FITC antibody-coated MPs formed a double-sandwiched immunocomplex. The measured relative light units (RLUs) of ABEI in the substrate solution were directly proportional to the amount of PCT present in the samples. The proposed method was linear to 600 ng/mL with a detection limit of 0.03 ng/mL. The coefficient of variation (CV) was <5% and <6% for the intra-and inter-assay precision, respectively. The average recoveries were between 95 and 107%. The linearity-dilution effect gave a linear correlation coefficient of 0.9912. This proposed assay provided an alternative method to quantitatively measure PCT in serum for the diagnosis of sepsis.
