Cell Pressure=142.76Torr, Cell Temperature=21.69C, Ring Time=11.939usec
2nd CH4 in air at 1400psi
CH4 Span=4.982ppm
CH4 = 4.959 -> 4.982 Offset: 23.000000000001ppb
Notes: Calibrated to check new 400ppm CO2 secondary standard. I took and average of 75 points as recorded in the LGR internal files and got a concentration of 3.856ppm CH4
