Dear everyone:

I am looking for a laboratory that can take commercial orders for boron
isotope analysis on ground water. The negative thermal ionization (NTI)
method may be needed due to the low concentration. I also need a lab to do
the mass spectrometry of chlorine isotopes which is already as CH3Cl. I
would appreciate receiving their phone numbers or E-mail addresses.

Regards.
