title: Cotton dust sampling, II--vertical elutriation.
abstract: Cotton dust sampling by vertical elutriation has existed since 1970. Early medical correlations using this method of sampling used median values instead of mean values because of unexpected high and low values. The methodology necessary to obtain consistent results is difficult to achieve and worthy of review.
