Intercomparison

Electrolytic tin plate is ideal for an intercomparison of the three methods, not only because of its great importance, but also because the value of a for tin is near 400, which corresponds to a relatively large linear range (Equation 6-9). Such an intercomparison was carried out10 with satisfactory results on standard samples on which the tin thickness was established by a chemical method. [Pg.158]

Chemisorption on nonmetallic catedysts should provide the number of catal3rtic sites and for comparative purposes a single Mg can be taken as a catalytic site on metals. This permits the calculation of turnover frequencies which was a new concept in post ICC 1 and which permitted intercomparison of catalyst activities. For the first time then, one has been able, for example, quantitatively to discuss support effects in Rh/support catalysts. [Pg.64]

On the other hand, reproducibility is the closeness of the agreement between the results of measurements of the same measurand carried out under changed conditions of measurement . The changed conditions include principle of measurement, method of measurement, observer, measuring instrument, reference standards, location, conditions of use, and time. Such variable conditions are typical for interlaboratory studies (laboratory intercomparisons). [Pg.204]

The mean radon concentrations determined by the passive detectors are based on calibrations using NBS standard radium-226 solutions and also from participation in the OECD (Nuclear Energy Agency)/CEC radon dosimeter intercomparisons (Commission of the European Communities, 1986) held at the U.K. National Radiological Protection Board (NRPB). Recent calibrations of the new LR-115 based detectors, in terms of response to radon concentrations and F factors have been carried out at the NRPB, which assistance is greatly appreciated. For the etching and track counting procedures used the inner LR-115 piece in the detectors has a mean sensitivity of approximately 1.6 tracks cm 2 kBq l m hr l. [Pg.123]
