Accuracy and Precision of Analysis of Light Hydrocarbon Mixtures

Abstract

CHEMISTRY extent, is of sufficient promise to justify further work with the method. Plans are being made to provide automatic temperature control, so that the test may be run overnight and hence reduce the time of test in terms of work days. ACKNOWLEDGMENTAcknowledgment is made to the laboratories which assisted in this investigation by supplying the oils tested. LITERATURE CITED(1) Coordinating Research Committee, "CRC Handbook," CRC

Determination of Benzene, Cyclohexane, and Methylcyclopentane by Mass Spectrometer

“…Reproducibility and accuracy of analyses of this type arc similar to those obtained by mass spectrometric analysis of gaseous hydrocarbon mixtures (10,14). As possible sources of error, consideration must be given to instrumental interference, adsorption on the walls of the inlet system, and volume effects on mixing.…”

Methods of determining the true accuracy of analytical methods

“…The question of evaluating methods of chemical analysis is not new; chemists have been interested in means of assessing the accuracy of methods of chemical analysis for many years (see ref [5][6][7][8] for some early approaches to this problem). These approaches included various ways of comparing the results of different methods.…”

Qualitative Analysis from Mass Spectra

“…peak-free regions to establish absence of fragments; comparison of peaks with those predicted from normal stable-isotope ratios; recognition of charaeteris-IX THE literature on mass spectrometric analysis, numerous articles have stressed accuracy of quantitative determinations and the speed with which they can be attained (6,7,10,(12)(13)(14)(15)(16). Little has been published, however, regarding the extensive use of the instrument in qualitative analysis.…”
