Introduction

LARA produces 4 types of Graphitized Carbon Black (GCB) at present, best known as Carbograph. Other types are under consideration at the moment.
The 4 types of Carbograph basically differ in their specific surface area.
GCBs are subjected to a special thermal treatment at very high temperature in an inert atmosphere. This process allows elimination of volatile compounds and tarry residues and gives to carbon the typical lamellar structure of graphite.
GCBs are adsorbents substantially non-porous, homogeneous and non-specific with a surface area between 13 and 240 m2/g.
For their unique adsorbent propriety they are used as stationary phase in gas-solid and gas-liquid-solid chromatography, for sample purification and in order to pre-concentrate volatile organic compounds from liquid or gaseous matrices.

The unique characteristics which distinguish the graphitized carbon blacks are:

chemical inertia
thermic and mechanical resistance
hydrophobia
non-porosity
high non-specificity
homogeneity of the crystalline structure

All GCBs produced by LARA are home-made, ensuring quality and lot-to-lot reproducibility.

Quality of our process of production and research are is guaranteed by ISO 9000 system, too.

CARBOGRAPH 1: specific surface area about 100 m2/g
CARBOGRAPH 2S: specific surface area about 13 m2/g
CARBOGRAPH 4: specific surface area 130 m2/g
CARBOGRAPH 5: specific surface area 240 m2/g The only GCB which shows porosity.
