Multisample dynamic headspace sampler

A manifold for an outgas test fixture for simultaneously sampling off-gassed organic compounds from a plurality of specimens in a plurality of sample chambers disposed in a heater block, said manifold comprising:

• an elongated pipe provided with a plurality of threaded holes;
• two pipe caps, one provided at each end of said elongated pipe;
• a connector disposed in one of said pipe caps, said connector being adapted to be coupled to a source of compressed gas;
• a plurality of metering valves, each individually connected to one of said threaded holes;
• a plurality of port connectors, each individually connected to one said metering valves;
• a plurality of tubing unions, each individually connected to one of said port connectors;
• a plurality of flexible tubes, each individually connected to one of said tubing unions;
• and
• a plurality of O-ring adapters, each individually connected to one of said flexible tubes, said O-ring adapters being adapted to couple to sample chambers disposed in a heater block.
