Subject: (Help) Methode for analysing Trichloroethylene

I'm a studend trying to analysed TCE (Trichloroethylene), and I need this info 
to start my work... but I looked in several web pages and did not find 
anything concerning the standard method for Trichloroethylene(even on Hach web 
site). I'm using a Hach DR 2500 spectrometer. 
-------------------------------------------------
nothing found at Hach concerning this parameter:

-------------------------------------------------------------------------------
Can you help me,....please I need to find a way to analysed TCE even if not 
using the Hach method ? This TCE contaminated a underground water supply few 
year ago and I want to validate if TCE is still present (maximum: 50 ppm)

Thanks Charlie
