“…Bright and Fletcher (74) have developed an RSP monitor that can collect two size fractions-"fine" (less than 2.5 ^tm) and "coarse" (2.5 to 10 am). Separate sampling heads can be attached to allow an upper cutoff of 7,10, or 15 /xm. A portable monitor, capable of determining mass but not chemical composition, has been designed by Sem and Homma (420) which employs the piezoelectric principle of measurement.…”

As analytical methodology improves and instrumental methods allow, or often require, the use of smaller and smaller analytical test portions, the error in the sampling operations becomes increasingly significant. Also, heterogeneity of trace components can introduce major sampling problems. Sampling errors cannot be controlled by use of blanks, standards, or reference samples and so are best treated independently.

“…Both of these are difficult to accomplish by extraction, but easily by adsorption. 4 Up to now only a few adsorbents have been reported for analyses to determine oil, [4][5][6][7][8] and there are several problems with such adsorbents. For example, some adsorbents have a low affinity for oil and adsorb too much water simultaneously; some adsorbents themselves are weakly soluble in organic solvents and produce interferences.…”
