6% Cyanopropyl-phenyl 94% dimethyl polysiloxane
In DB-624, the stationary phase is a phenyl arylene polymer that has a 6% cyanopropyl substituent. This phase is commonly used in gas chromatography for separating a wide range of analytes, especially non-polar and moderately polar compounds.
mobile phase is the phase that consist of the analyte and stationary phase is the phase that is standstill
In chromatography, the mobile phase is the solvent that carries the sample through the stationary phase. The stationary phase is the material that interacts with the components of the sample, causing separation based on differences in their affinity for the stationary phase.

The stationary phase in paper chromatography is the paper itself.
The polarity of the stationary phase is critical in determining the interactions between the compound and the stationary phase. Compounds with similar polarity to the stationary phase will interact more strongly and be retained longer, leading to better separation. Conversely, compounds that are less polar than the stationary phase will elute faster.
Chromatography is a method of separation that employs a system with two phases of matter – a mobile phase and a stationary phase. The mobile phase carries the mixture to be separated through the stationary phase, where the components separate based on their interactions with the stationary phase.
H2O (water) is not typically used as a stationary phase in chromatography. Instead, it is commonly used as a mobile phase due to its excellent solvating capabilities. Stationary phases in chromatography are usually solid supports or coated surfaces that interact with the analytes being separated.
Reverse phase chromatography and normal phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary phase and mobile phase. In reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar. This polarity difference affects how compounds interact with the stationary phase, leading to differences in separation and elution times.
In reverse phase HPLC, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase HPLC, the stationary phase is polar and the mobile phase is nonpolar. This difference in polarity affects how compounds interact with the stationary phase, leading to variations in separation and elution times.
The stationary phase in paper chromatography acts as a medium for separating different components of a mixture based on their affinity for the stationary phase. It helps to slow down the movement of the components as they travel through the paper, allowing for the separation based on their different interactions with the stationary phase.
