Dear All,
I am using ThermoFinnigan Delta Plus XP (NGRI, Hyderabad India) coupled 
with Flash EA (1112) for the last one year. Off late I am experiencing 
some problem with CO2 peak shapes and 13C values. I have replaced the 
reactor by refilling fresh chemicals but still the problem persists. Could 
anybody help me in directing me to a reliable source for tin/silver 
capsules and chemicals for both the reactors.
Thanks

D J Patil
