■ CHIRA-GROM phases                                              

Five different CHIRA-GROM matrices are available：CHIRA-GROM-Phases Type 1-4 and 9 consist of spherical, highly porous 8μm silica particles specially treated by a novel thermal process and covered with layers of synthetic chiral polymers. Separation of chiral molecules can easily be achieved in the normal phase as well in the reversed phase mode.

 

■ Capillaries for Capillary Electrophoresis (CE)                        

GROM FuSi-untreated capillary：It features a high degree of free silanol groups for enhanced EOF. They are excellent for dynamic- or custom permanent coating.

GROM FuSi-deactivated capillary：It is optimized to reduce the wall adsorption caused by active silanol sites and thus yield highly reproducible results for instance when analyzing proteins and or peptides in non-denerurating conditions.

GROM FuSi-PEG100 coated capillary：It could be used for analysis of proteins, peptides, nucleotides and etc by CE. It features a weakly hydrophilic , PEG-100 coated surface that exhibits low hydrogen bonding surface. This prevents the reactive regions of proteins from interacting with the silanol sites and nearly eliminates the electro-osmotic flow.

GROM FuSi-PEG-β-cyclodextrin coated capillary：The cyclodextrin acts as a selective complexing system. This capillary column permits separation of a huge variety of optical and positional isomers by HPCE. Its use has also shown to be effective in the resolution of pharmaceutical enantiomers and inorganic ions.

GROM FuSi-200 HS capillary：It used for MEKC feature a chemically and hydrolytically stable, hydrophobic coating for separation by capillary electrophoresis.

 

■ Capillaries for Capillary Electrochromatography (CEC)       

Electrochromatography represents most exciting, recent development in the field of separation technologies. This unique method combines all the outstanding features and benefits inherent in modern HPLC and advanced capillary electrophoresis. It is readily performed in either the isocratic or in the gradient mode. Exceptional separations can thus be achieved when employing capillaries < 150 mm in length packed either with porous or non-porous micro-particles. The electro osmotic flow eliminates restrictions in the length of the column normally encountered with small particle sized packings as result of prohibitionally high backpressures.

　

 ■ Columns for Combinatorial Chemistry                              

Combinatorial Chemistry: One of the most advanced, modern technologies requires a broad range in selectivity and excellent stability of stationary phases, while maintaining column durability and efficiency with good peak symmetry, especially for basic and acidic compounds. These important features are only guaranteed by a couple of the commonly available stationary phases such as GROM-SIL phases.
