Can you forward this to see if they have any thoughts on who to purchase these liquid standards from?  We've tried Eckhard and Ziegler and they are unable to provide the concentration levels we are requesting.
Cl-36:  0.5 to 0.65µCi (~2.28E+04  Bq) in 100mL of 0.1M HCl

2.                              H-3:  1 to 1.2µCi (~3.72E+04  Bq) in 100mL DI
