      <subfield code="a">Use of adsorbent tubes for sampling airborne contaminants has become increasingly popular in the past two decades. This is in part because of the development of improved absorbents (possessing more homogeneous adsorbent surfaces) allows for better adsorption and desorption of the contaminants of interest</subfield>
