Claims23
A passive air sampler comprising (a) a frame defining at least two chambers (b) at least two air contaminant collecting units adapted for placement in said at least two chambers, (c) an air-permeable barrier for covering said at least two chambers, and (d) a removable sleeve for sealing all of said at least two chambers when said air sampler is not in use.
A passive air sampler comprising (a) a frame defining at least two chambers (b) an air contaminant collecting unit in each of said at least two chambers, (c) an air-permeable barrier covering said at least two chambers containing said air contaminant collecting units, and (d) a removable sleeve covering said barriers and sealing said at least two chambers when said air sampler is not in use.
A passive air sampler comprising (a) a frame defining at least two chambers (b) at least two air contaminant collecting units adapted for placement in said at least two chambers, (c) at least two air-permeable barriers for covering said at least two chambers, and (d) a removable sleeve for sealing all of said at least two chambers when said air sampler is not in use, wherein the passive sampler is capable of multiple flow rates.
