Answer Posted / kanakadurga
Packed columns have higher sample capacity than capillary
column.
Improvements in detector sensitivity have also reduced the
need for large samples.For almost all other samples,
capillaries provide much better efficiency (narrow peaks)
which leads to greatly improved peak separation. Capillary
columns are highly sensitive and efficient. these are two
types WCOT and PLOT.
Yes these are depends on Sample Load. Very Low quanity of
samples are enough for the analysis.

In BP2013, Loperamid HCl monograph. Assay by titration with 0.1N sodium hydroxide using hydrocloric acid 0.01N and reading the volume added between the 2 points of inflexion. I have a question that if the diluent solvent is ethanol is certainly consumed a amount of volume of titrant, so this volume must be eliminated on the result calculation or not apart from first point which is subtracted above.

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?
