Claims21
A sample bag for collecting a mixture of gases for analysis, the sample bag being made of a modified polymer consisting essentially of tetrafluoroethylene and at most about 2.0% perfluoropropylvinylether.
A method of collecting a diluted exhaust gas mixture from an internal combustion engine, the method comprising:
- receiving an exhaust gas mixture;
- receiving a dilution gas;
- mixing the dilution gas with the exhaust gas mixture to form the diluted exhaust gas mixture;
- and
- collecting the diluted exhaust gas mixture in a sample bag, the sample bag being made of a modified polymer consisting essentially of tetrafluoroethylene and at most about 2.0% perfluoropropylvinylether.
A sample bag for collecting diluted exhaust gases from an internal combustion engine, the sample bag comprising:
- a boundary structure defining a container for the gases, the structure being made of a modified polymer consisting essentially of tetrafluoroethylene and at most about 2.0% perfluoropropylvinylether;
- and
- an inlet connected to the structure for receiving the gases .
