Summary: Calibrated LGR, replaced filters, downloaded data

Arrived 1:37pm
First opened box:
CO2 418ppm
D13C -14 per mil
D18O = -70 per mil
H2O = 322.6ppm
Gas Temp=44.85C
Gas Pressure = 119.78 Torr
Laser response = 12.85 us
Laser adjust looked a little off
Initial Laser voltage=2.035
Post adjustment=2.0376

Changed out all filters on tower inlets
Connected NOAA standard tank
PSI=1800
2nd stage PSI=10
Decided to not â€œcalibrateâ€ laser, best to do that in the lab with temperature controlled conditions
First ran NOAA, old standard (from Joe) and new standard (Praxair CO2 400ppm)

Set new program, sampling from new standard every 2 hours
Sequence:
Valve, Sec, ID
2, 300, Ref gas
1, 6600, tower
4, 300, 1.5m
3, 300, 3m
