Molecular formula : CAS :
nature : impure from the mobile phase chromatographic peak-called hole. For example, when the carrier gas impurities, hydrogen flame ionization detector analysis of the low boiling point, low concentrations of the gas components, there will be negative peaks. Hence, the use of impure mobile phase sometimes fail to obtain reliable results.
