Can you prepare the alkane standard in a different alkane, maybe heptane or octane? Boiling point of n-pentane is fairly close to room temperature (36 C) so you may be getting some evaporation of the lighter components in the sample. If there's enough…
Very useful video for basic understanding of the valve functionality. can you post some more videos on GREEN HOUSE GAS ANALYZER or TOGA System in this impressive and easiest way only.
This should take less than one hour. The ion source and quad(s) only need to be below 100° C and the high vacuum pumps - diffusion pump off and cold or the turbo pumps not spinning. Make sure that the GC transferline temperature is set to OFF or 0° C…
The GC inlet must have 20 ml/min or more total flow for good inlet pressure/flow control. If the total flow is too low, air can actually diffuse into the system and the oxygen will damage the column.
Using an Agilent Headspace Sampler the samples are…
