What Is Schematic Flow Diagram Of Gas Chromatography?

Definition of terms:
Homogenous mixture: mixture containing substances present in the same phase e.g DCM dissolved in distilled water (liquid-liquid).
Heterogeneous mixture: mixture containing substances existent in different physical states e.g sodium pellets in paraffin (solid-liquid).
Analyte: this is the component of interest in a sample.
Interferent: Substance that has physical or chemical properties close to those the analyte.
Matrix: all different materials in a sample besides for the analyte.
Selectivity: is a measure of the degree to which a method is affected by interferents and this is defined by the value of the method selectivity coefficient.
Mobile phase: is the extracting segment that runs across the system
Stationary phase: is the segment that is static across which the mobile phase moves

Fig 1: Schematic Flow Diagram of Gas Chromatography
The GC system consists of mobile phase which contains the carrier gas, an injector block, flow meter and oven as shown in figure 1.0. A format which may be gas or liquid is first passed into a stream of lethargic gaseous mobile stage setup with a pressure regulator. The lethargic gaseous mobile phase

In Support-coated open tubular columns (SCOT), a thin segment of a firm support, which includes a diatomaceous earth, lined with a liquid stationary phase which then is connected to the capillary’s internal wall. Capillary columns offer a massive development in separation efficiency. The stress needed to move the cell phase through a packed column limits its period. The absence of packing material lets in a capillary column to be longer than a packed column. Although most capillary columns comprise greater theoretical plates per meter than a packed column, the extra important contribution to their extra efficiency is the capacity to create longer
