The　testing　of　indoor　air　is　a　process　of　collecting　air　sample　and　analyzing　air　sample.　Every　step　may　affect　the　results　of　the　detection.　As　we　know,　sampling　is　the　base　of　measurement.　The　veracity　will　be　affected　by　collecting　methods　and　tools.　In　this　paper,　the　sampling　tubes　were　summarized,　which　involved　the　property　and　type　of　adsorbent,　the　specification　and　material　of　sampling　tube,　and　so　on.　In　the　end,　some　advices　have　been　brought　forward　to　the　study　and　development　of　the　sampling　tube　in　the　future.
