Apparatus module for collection of volatiles from test sample

An apparatus for the collection of volatiles produced during solution photolysis of a test sample, comprising:

• multiple transparent vessel means for holding the test sample;
• vapor collection adapter means connected to each vessel means for sealingly engaging and closing said vessel means;
• means for sealingly connecting said vapor collection adapter means together in series;
• means for mounting said vessel means so as substantially avoid any obstruction to the passage of light to said test sample in said multiple vessel means;
• means for pumping gas serially through said multiple vessel means so as to carry volatiles emitted by said test sample;
• and
• trap means for collecting volatiles carried by said gas being pumped serially through said multiple vessel means whereby volatiles produced by the test sample in said multiple vessel means may be collected for analysis and the test sample in one of said vessel means may be analyzed without substantially disturbing another test sample in another of said multiple vessel means.
