80Å Monomeric Reversed Phase Silica

For analysis of small molecules, the 100 Å pore size, 5 micron particle size 80Tm and 80Ts columns are offered in 4 different chemistries to suit a variety of needs. The Type B base silica is of high purity and contains few metal ion impurities. Combined with monomeric bonding chemistry, these reveresed phase columns have an established reputation as general purpose columns for pharmaceutical applications.

The monomeric materials are delineated by the following nomenclature:

• Bonded phase pore size is indicated by the number in the product description, for instance, ODS-80Ts has 80 Å nominal pore size. The pore size of the base silica is 100 Å.  
• T denotes an endcapped phase. 
• M, as in 80Tm, indicates that a regular endcapping Rx has been performed. 
• S, as in 80Ts, indicates a more exhaustive endcapping Rx has been performed. 
• QA in ODS-80Ts QA indicates maximum lo-to-lot reproducibility of retention and selectivity
