gc and gc-hs both are used for residual solvents in by gc
we measured for volatile solvents in this direct inject the
sample into the column and in gc-hs is also used for
volatile sovents in this we apply the pressure to inject
the solvent as vapour into the column
and both r used for non volatile solvents there are
converted into voltile solvents

I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
