TRACER EXTRASIL

The new range of TRACER EXTRASIL packings has been specially developed to replace one of the most popular spherical packings in the market viz. Spherisorb.

All physical and chromatographic parameters evaluated prove a total equivalency between both packings. What is more important, has been proved by good result obtained at laboratories worldwide.

Economy

TRACER EXTRASIL packings represent the most economical alternative.

Reproducibility

An advanced manufacturing process and strict control tests ensure that each one of the processing phases are characterised by an excellent reproductibility and maximal efficcacy in each and every column.

Material characteristics

As the following table shows, the new TRACER EXTRASIL, packing is perfectly equivalent to the speherical reference packing in all of its physico-chemical chracteristics.

Particle Size Distribution

In the development of this view material, we have taken special care in the optimisation of the particle size in order to achieve columns of maximum efficiency and stability.

Comparision with the Spherisorb packing shows one more the total equivalency between both materials.

SEM of Base Silica

The resulting packing shows a practically perfect sphericity between

Application

Despite the significance of all of the data shown above, a definitive proof on the equivalency of both packings is given by their comparision in a wide range of applications.

The following chromatograms dispel any doubts on the exact equivalency between the new TRACER EXTRSIL packing and the reference Spherisorb packing.
