What are the factors affecting peak tailing in GC ?
Hi koti.vanga,
Peak tiling can happened by many reasons
1- Contaminated injector liner this solved by clean or replace injector liner,Contaminated column Bake out the column
Cut 4 inches off the end of the column.
2-poor installed column and liner ,and this confirm by injecting inert peak(methane) if it tails, column is not properly installed. Reinstall liner and column.
3-Split ratio is too low Increase split ratio to at least 20/1.
so we need more information like inlet,split ratio,.......is Mr.James referred.
Best regards
