Gas Chromatography A retention gap is placed between the injector and the front of the column to prevent backflush of the injected solution retain the sample and release it gradually to the column All of these retain contaminants and prevent them from reaching the column prevent backflush of the injected solution retain the sample and release it gradually to the column All of these retain contaminants and prevent them from reaching the column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Column bleeding occurs when the column is cracked and stationary phase leaks out the column breaks during installation and causes personal injury traces of the stationary phase are eluted elution of the analyte is extended over time the column is cracked and stationary phase leaks out the column breaks during installation and causes personal injury traces of the stationary phase are eluted elution of the analyte is extended over time ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Resolution is proportional to the square of the number of theoretical plates in a column number of theoretical plates in a column cube root of the number of theoretical plates in a column square root of the number of theoretical plates in a column square of the number of theoretical plates in a column number of theoretical plates in a column cube root of the number of theoretical plates in a column square root of the number of theoretical plates in a column ANSWER DOWNLOAD EXAMIANS APP
