peak dispersion
1.The effect of flow rate on peak current and dispersion in FIA system was discussed. The method of measuring the apparent activity of the open tubular immobilized enzyme reactor was suggested.
2.It is concluded that as second order dispersion compensation can avoid pulse broadening, third order dispersion compensation not only can avoid pulse broadening, but also eliminate pulse edge′s oscillating and temporal shift of pulse peak.
3.To evaluate the feasibility of Q T d measurements under circumstances of body surface potential mapping(BSPM), QT p d(dispersion of interval of Q wave onset to T wave peak) was observed by using a computerized automatic mapping system in 80 normal individuals. The findings were compared with the 12 lead Q T d(the dispersion of Q T interval).
4.In this paper, TPD (TemperatureProgrammed Desorption) of adsorbed carbon dioxide, oxygen, carbon monoxide and butylamine were used to investigate species and dispersion of active sites on SrO It was found that the desorption peaks of carbon dioxide appeared at 921K and 1173K if carbon dioxide was adsorbed for enough time, otherwise, only one desorption peak of carbon dioxide appeared at 1173K;
