Chromatography
Technique 4 separation/identification of molecules based on differential affinity
- Can be used for qualitative testing
- Qualitative- how much substance you have
- Differential Affinity - to attach to something (weak Bond)
- Strong Bond - are Stable
- Weak Bond- Hydrogen- Hydrophobic = Flexibility
- DNA-2 Strands= Flexible
- Weak Bond- Hydrogen- Hydrophobic = Flexibility
- Strong Bond - are Stable
- 2 Phases of Chromatography
- 1st- Stationary (Cellulose paper) can be known/unknown
- 2nd- Mobile ( Liquid) Solution will pass over stationary
- Separation = Decanting
- Each samples has their own differential affinity
- Affinity can identify chemical and allows you to identify them as well
- Capillary Action- movement of fluid, up thin glass
- Adhesive- unlike molecules
- Cohesive- same molecules
- Water has both Cohesive/Adhesive properties
- Cohesive- same molecules
- Cohesive Color moves up together
- Colors adhere to paper
- Affinity can identify chemical and allows you to identify them as well
- Each samples has their own differential affinity
