SECOND SELECTION CRITERIA
FOR INVOLATILE MATERIALS





General Information
 

You have arrived here because your molecule is insufficiently volatile for analysis directly from the gas-phase.  There are further criteria that need to be considered.

To simplify your choices, select one from the following two statements that best describes your sample.
 
 
 
 " The molecular weight is greater than  2,000Mass > 2000.

 
 " The molecular weight is less than 2,000Mass < 2000  .
