diamond tailing sampling

GC Diagnostic | Peak Tailing

This special case of peak tailing is usually accompanied by a loss of peak efficiency (peak broadening). If gross stationary phase contamination is suspected, and all other possible causes mentioned above have been explored, trim at least 20cm from the inlet end of the column, re-fit and assess peak shape with a sample or test mix.
