The certification of the surface density (kg/m sub 2 ) of BCR CRM 038 ('fly ash from pulverised coal') comprised in methyl cellulose films simulating dust charged filters. BCR 128

Technical Report:

Abstract

BCR CRM 38 ('Fly Ash') has been embedded in a stable methylcellulose foil of about 10{mu}m thickness. This has been done by making a slurry of fly ash and methylcellulose in water and spiking it with {sup 42}K as a radioactive tracer. The slurry was spread over glass plates and allowed to dry. 'Filters' of uniform size were punched out of the foil. The surface density (e.g. {mu}g/cm{sup 2}) of the fly ash was calculated for each individual 'filter' by comparing the {sup 42}K-activity of the filter with that of the initial suspension. The uncertainties in the so obtained surface density of random and of systematic origin have been estimated. The total relative uncertainty in the surface density of every element certified in BCR 38 is 4-6%. Studies of stability and homogeneity have revealed that this material is well suited for the verification of the results of non-destructive analytical techniques for dust components.
