  • 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
