Phase 1: A temporary solution• Quality of sampling may* not be sufficient– Aspiration of air may have to be revised– Long tubing with bends• Short Lived Gases: decay in the sampling tube• Particles: Losses in the long straight sections and bends,

tubing material may not be adequate• Plastic tubing
