Gas Chromatography Column bleeding occurs when traces of the stationary phase are eluted the column is cracked and stationary phase leaks out elution of the analyte is extended over time the column breaks during installation and causes personal injury traces of the stationary phase are eluted the column is cracked and stationary phase leaks out elution of the analyte is extended over time the column breaks during installation and causes personal injury ANSWER DOWNLOAD EXAMIANS APP
