Function of internal standard in Gas chromatography

Some points on function of internal standard in gas chromatography are:

• An internal standard compensates for variations in sample evaporation by reflecting losses that occur before column entry.
• It adjusts for minor changes in split or splitless injection behavior by responding proportionally under the same injection mode.
• The internal standard accounts for short-term fluctuations in carrier gas flow by exhibiting parallel response changes during analysis.
