Most of these analyses we obtained during 1966 withequipment and techniques previously employed.Methane from the higher numbered samples wasproduced in a bomb reactor at pressures up to 1000psi. Also, many smaller samples were counted in a700-ml vol counter at 2 atm pressure, which has abackground of 1.76 = .02 counts/min.
