2 Inertness and Durability combined in a new HPLC column TM InertSustain C8 Generally, silica based columns are mechanically stable and provide high efficiencies, however, they cannot be used under alkaline conditions and their residual silanol groups tend to adsorb organic bases. InertSustain C8 employs a radically new type of silica, in which the surface of the silica is uniquely modified, enabling precise control of the silica properties. InertSustain C8 inherits the advantages of all the current Inertsil HPLC columns (e.g., extremely low operating back pressure, superior inertness to typically any analytes, high efficiency and compatibility with a wide range of solvents), but now can be used for wide ph analysis with consistent performance from column to column and lot to lot. st Stage [ Synthesi sis of Evolved Surface Silica] InertSustain C8 features Unmatched Inertness and Durability nd Stage Radically New Silica Gel It is not possible to end-cap 00 % of residual silanols using traditional chemical modification procedures. GL Sciences studied the possibility of developing a radically new type of silica, a silica that would provide both high inertness (base deactivation) and durability at a wide range of ph. st Stage [Synthesis of Evolved Surface Silica ] As the adsorption sites and silanol distribution are strictly controlled from the synthesis procedure of the Evolved Surface Silica, InertSustain C8 delivers unmatched inertness to virtually any type of analyte with high durability to acidic, basic mobile phase conditions. nd Stage [Chemical Bonding of ODS group] The introduction of Evolved Surface Silica and our cutting-edge chemical bonding technology make InertSustain C8 compatible with 00 % aqueous mobile phases, while maintaining strong non-polar retentivity. rd Stage [Complete End-capping] GL Sciences complete end-capping technology allows InertSustain C8 to provide high efficiency and superior peak shape even to those well-known strong adsorptive analytes.

Surface Silica leads to efficient method development at a wide range of ph, creating the possibility of unique selectivity changes.

C8 delivers highly stable chromatograms for qualitative and quantitative analysis for all compounds.

Some samples require high ph for dissolution or to maintain stability. InertSustain C8 would be the first choice column for such applications.

Superior Peak Shape with Better Resolution As the adsorption sites and silanol distribution are strictly controlled on the Evolved Surface Silica, InertSustain C8 delivers highly stable chromatograms for qualitative and quantitative analysis for all compounds. Wide ph Compatibility and High Durability InertSustain C8 is highly durable to acidic and basic mobile phases and can endure from ph to 0. Some samples require high ph for dissolution or to maintain stability. InertSustain C8 would be the first choice column for such applications. Strict Quality Control Program results in High Reproducibility Since the entire manufacturing process is under the control of our factory in Japan,reliable and consistent performance from column to column and lot to lot can be stably supplied. Unmatched Operating Back Pressure Due to the low operating back pressure that InertSustain C8 offers, it can still deliver low pressure even using high-viscosity solvents.

4 Quality and Performance of TM InertSustain Tailing of peaks or adsorption of peaks can be experienced when a column has residual adsorption sites. Such phenomenon would not be observed on InertSustain as the silanols are completely end-capped, having a neutral silica surface. To maintain precise product reproducibility, strict chromatographic tests for inertness, durability, theoretical plates and reproducibility of retention time are employed. Basic Compound Berberine chloride and Dextromethorphan is a strong basic compound. Severe tailing can be confirmed when the packing material contains residual silanol groups. As shown on the right, InertSustain delivers highly stable chromatograms for qualitative and quantitative analysis. Column Size : m 0. mm I.D.
