HiQ sil C18 HS high performance high resolution columns

Outstanding loadability.

• Effective end-cap to minimize residual free silanol.
• Outstanding acid and alkalinity resistance.
• Excellent reproducibility.
• Long life time – highly durable.
• High pH tolerance for acid and alkali.
• Good retention even with 100% aqueous eluents.

All HiQ sil C18HS columns have been tested to guarantee that every column gives excellent performance at the customers’ site. A validation certificate is included with every HiQ sil C18HS column.

Excellent peak shape

The new HiQ sil C18 HS packing material has great peak symmetry characteristics. NMR data shows that the free silanol groups are completely undetectable. The carbon loading is around 17%. Even with difficult materials the new HS packing offers great resolution with virtually no tailing

Effective newly developed high carbon loading end-capping method has dramatically improved peak shape; this is due the near absence of free silica moieties. There is virtually no tailing on the peaks and excellent symmetrical peaks can be obtained from every HiQ silTM C18HS column

Excellent Sample Loading

HiQ sil C18HS has been developed for sample capacity whilst retaining good peak shape. The new packing material has shown a capacity up to 3 times higher than some popular brands. The key benefit of this new packing material is evident in preparative chromatography where you can obtain more material from fewer clean-up cycles, but it also aids regular chromatography for users that need to measure differences between very large and very small peaks; you can now improve the chromatography by loading the column with more material to improve the smaller peak’s signal to noise.

Wide pH Tolerance in Both, Acid and Alkali Mobile Phases

HiQ sil C18HS has been tested for lifetime durability in both acid and alkaline mobile phases. The lifetime at pH 2.0 and pH 12.0 is around double when compared to many of the conventional silica technologies currently available.

Even with 100% aqueous mobile phase, the HiQ sil C18HS show good retention.
