Gas Chromatography Column bleeding occurs when 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 traces of the stationary phase are eluted ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Sample injection is considered successful if the sample is spread evenly along the column the sample is concentrated at the start of the column all of the sample in the injector has been added to the column the sample is homogenously spread along the column the sample is spread evenly along the column the sample is concentrated at the start of the column all of the sample in the injector has been added to the column the sample is homogenously spread along the column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography In column switching chromatography any of the above one column is removed and replaced by another the flow to the column is switched on and off repeatedly compounds trapped on one column are eluted to another column any of the above one column is removed and replaced by another the flow to the column is switched on and off repeatedly compounds trapped on one column are eluted to another column ANSWER DOWNLOAD EXAMIANS APP
Gas Chromatography Split injection is carried out by splitting off some of the sample so that it does not enter the column splitting the sample into smaller portions to inject sequentially None of these splitting the sample into smaller portions to inject at the same time through parallel ports splitting off some of the sample so that it does not enter the column splitting the sample into smaller portions to inject sequentially None of these splitting the sample into smaller portions to inject at the same time through parallel ports ANSWER DOWNLOAD EXAMIANS APP
