  - IOP Conference Series: Materials Science and Engineering - Rok 2016

  Semiconductor gas sensors are popular commercial sensors applied in numerous gas detection systems. They are reliable, small, rugged and inexpensive. However, there are a few problem limiting the wider use of such sensors. Semiconductor gas sensor usually exhibits a low selectivity, low repeatability, drift of response, strong temperature and moisture influence on sensor properties. Sample flow rate is one of the parameters that...

  - Rok 2015

  This paper describes an amperometric sensor module for gas concentration measurement. A module can be used for many types of electrochemical gas sensors without major hardware changes. Device is based on AVR ATmega8 microcontroller. As signal processing circuit a specialized integrated circuit LMP9l000 configurable via I2C interface is used. The concept of a measuring system composed of several modules dedicated for a gas sensors...

• Non-matrix reference materials-the challenges in the preparation of standard gas mixtures

  Publikacja

  • M. Słomińska
  • P. Konieczka
  • J. Namieśnik

  - Rok 2011

  In the last few years particularly great pressure is exerted on quality control and assurance of analytical measurement results. An invaluable role in this process is played by reference materials. The paper presents the characteristics of basic types of reference materials, with particular attention to gaseous reference materials.

• JMATRIX - a package for relativistic J-matrix calculations in elastic scattering of electrons from model potentials

  Publikacja

  • P. Syty
  • J. E. Sienkiewicz

  - TASK Quarterly - Rok 2017

  We present a software package JMATRIX, consisting of two computer codes written in FORTRAN 95 and parallelized with OpenMP, implementing the so-called J-matrix method, applied to elastic scattering of electrons on the radial potential, vanishing faster than Coulomb one. In the J-matrix method, physical scattering problem is replaced by using well-defined model, which is solved analytically. Presented software implements both non-relativistic...

• Determination of Odor Air Quality Index (OAQII) Using Gas Sensor Matrix

  Publikacja

  • D. Dobrzyniewski
  • B. Szulczyński
  • J. Gębicki

  - MOLECULES - Rok 2022

  This article presents a new way to determine odor nuisance based on the proposed odor air quality index (OAQII), using an instrumental method. This indicator relates the most important odor features, such as intensity, hedonic tone and odor concentration. The research was conducted at the compost screening yard of the municipal treatment plant in Central Poland, on which a self-constructed gas sensor array was placed. It consisted...
