Columns

• Solid Support - Backbone for bonded phases.    
• Usually 10µ, 5µ or 3µ silica or polymeric particles.
• Bonded Phases - Functional groups firmly linked (chemically bound) to the solid support.            
• Extremely stable
• Reproducible
• Analytical - Performs the separation.
• Guard - Protects the analytical column
• Particles
• Interferences
• Prolongs the life of the analytical column
