  • the Analytical Calibration in bio imaging mapping of the metallic elements in biological samples definitions nomenclature and strategies state of the art
    Talanta, 2015
    Co-Authors: Kamil Jurowski, Boguslaw Buszewski, Wojciech Piekoszewski
    Abstract:

    Nowadays, studies related to the distribution of metallic elements in biological samples are one of the most important issues. There are many articles dedicated to specific Analytical atomic spectrometry techniques used for mapping/(bio)imaging the metallic elements in various kinds of biological samples. However, in such literature, there is a lack of articles dedicated to reviewing Calibration strategies, and their problems, nomenclature, definitions, ways and methods used to obtain quantitative distribution maps. The aim of this article was to characterize the Analytical Calibration in the (bio)imaging/mapping of the metallic elements in biological samples including (1) nomenclature; (2) definitions, and (3) selected and sophisticated, examples of Calibration strategies with Analytical Calibration procedures applied in the different Analytical methods currently used to study an element׳s distribution in biological samples/materials such as LA ICP-MS, SIMS, EDS, XRF and others. The main emphasis was placed on the procedures and methodology of the Analytical Calibration strategy. Additionally, the aim of this work is to systematize the nomenclature for the Calibration terms: Analytical Calibration, Analytical Calibration method, Analytical Calibration procedure and Analytical Calibration strategy. The authors also want to popularize the division of Calibration methods that are different than those hitherto used. This article is the first work in literature that refers to and emphasizes many different and complex aspects of Analytical Calibration problems in studies related to (bio)imaging/mapping metallic elements in different kinds of biological samples.

  • a 77 ghz six port fmcw collision avoidance radar sensor with baseband Analytical Calibration
    Microwave and Optical Technology Letters, 2009
    Co-Authors: B Boukari, E Moldovan, Razvan I Cojocaru, Sofiene Affes, Ke Wu, R G Bosisio, S O Tatu
    Abstract:

    A 77-GHz six-port frequency modulated continuous wave collision avoidance radar sensor is proposed. Velocity and range are determined from the slope of the instantaneous phase of radar beat signals. Digital signal processing techniques are developed to overcome DC offset and amplitude imbalance problems. © 2009 Wiley Periodicals, Inc. Microwave Opt Technol Lett 51: 720–725, 2009; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.24144

  • univariate Analytical Calibration methods and procedures a review
    Analytica Chimica Acta, 2016
    Co-Authors: Pawel Kościelniak, Marcin Wieczorek
    Abstract:

    An original focus on univariate Calibration as an experimental process of quantitative analysis is presented. A novel classification system is introduced against the background of the present situation concerning nomenclature of Calibration methods. Namely, it has been revealed that four methods well-known in Analytical chemistry: the conventional method, the internal standard method, the indirect method and the dilution method, can be split into those carried out in both the interpolative and the extrapolative mode. It is then shown that the basic procedures of all these methods can be modified including different approaches, such as matrix-matched technique, spiking the sample with a reactant, bracketing Calibration, and others. For the first time (as compared to monographies dealing with univariate Calibration) it is reviewed how the methods are mixed and integrated with one another thereby creating new Calibration strategies of extended capabilities in terms of enhanced resistance to the interference and non-linear effects – as the main sources of systematic Calibration errors. As additional novelty, rationally possible combinations of the Calibration methods – not met hitherto in the literature – have been predicted. Finally, some general rules relating to Calibration are formulated and the main Calibration problems that still need to be solved are displayed.

  • versatile flow injection manifold for Analytical Calibration
    Analytica Chimica Acta, 2007
    Co-Authors: Pawel Kościelniak, Marcin Wieczorek, Joanna Kozak, Malgorzata Herman
    Abstract:

    A flow injection Calibration system, originally designed and tested in our laboratory, is presented here as a versatile Analytical tool serving for Calibration purposes. It is characterized by a simple construction, easy operation and the possibility of offering rich measurement information with the use of a single standard solution. It is shown that depending on instrumental conditions and the composition of the Calibration solutions the manifold is able to realize various Calibration procedures according to interpolative, extrapolative and integration modes. As an experimental example, the determination of calcium in the cabbage sample by flame atomic absorption spectrometry has been calibrated by means of dilution method (DM) in the integration mode.

  • Calibration Problems in Trace Analysis
    Handbook of Trace Analysis, 2016
    Co-Authors: Paweł Kościelniak, Marcin Wieczorek, Joanna Kozak
    Abstract:

    An entire Analytical procedure (i.e., a group of activities leading to information on either the kind or quantity of a component in the sample assayed) consists of several separate stages. If the final goal of this procedure is a quantitative result, one of the essential stages is Analytical Calibration.
