Hello Rick,

I have just a remark on CP-PoraPLOT. We exchanged for our methane work the
original CP-PoraPlot against a CP-PoraBond Column without problems in gas
peak separation and peakshape (CO,CH4,CO2,N2O). The advantage of PoraBond
is from my experience that it is mechanically much more robust (pressure
pulses, temperture change) without the need of a particle trap or any
further problems with particles blocking the GC flow or traveling through
the system behind the column  (the stationary phase of this column is
polymerised and cross-linked forming a stable layer).

Best regards

Klaus-Uwe
