ODS 3.0

Tracer Excel ODS-A is a fully end-capped packing, notable for its extreme level deactivation.

This minimizes undesirable interactions when chromatography strong acidic or basic analistes or chelating compounds.

Additionally Tracer Excel ODS-A columns show extraordinary resistance to extreme pH values, between 1.5 to 11.0

Compatible with 100% aqueous eluent.

Especially suitable for the separation of hydrophilic compounds.

Strong retention in aqueous eluents.

Long useful life with aqueous eluents.

Selectivity complementary to Tracer Excel ODS-A.

High mechanical stability.

Maximum versatility.

Effect of Aqueous elutants on the organization of hydrocarbon chains
