Grom HPLC Columns
NovoGROM low-dispersion, high speed HPLC columns
The comparatively short NovoGrom columns enable highly efficient and particularly fast chromatography. You can choose between capillary columns, microbore columns, analytical, semi-preparative and preparative columns with different inner diameters.
GROM SIL Phases
GromSil phases are characterized not only by high chemical selectivity, but also by their excellent physical properties: they are absolutely spherical, completely porous and have a high specific surface area. As a result, GromSil-packed columns exhibit excellent flow properties (e.g. low backpressure) as well as particularly high efficiency and peak symmetry.
Eight different SIL-ODS phases and six different SIL-Octyl phases have been developed to offer the widest possible range of selectivities, which are excellent even for complex separations.
GROM SIL C18 phases
| GROM-SIL 100 ODS-0 AB | High-quality phase with special endcapping for the outstanding separation of acids and bases. |
| GROM-SIL 100 ODS-1 PE | Economical phase with partial endcapping and high selectivity. |
| GROM-SIL 100 ODS-2 FE | Fully endcapped stationary phase with outstanding selectivity for most applications. |
| GROM-SIL 120 ODS-3 CP | Encapsulated, chemically stable phase with metal-free silica gel matrix. |
| GROM-SIL 120 ODS-4 HE | High resolution - a new hydrophylic endcapping makes this phase especially suitable for peptides. |
| GROM-SIL 120 ODS-5 ST | Standard phase for practically all applications. |
| GROM-SIL 120 ODS-6 NE | ODS phase for special applications. High hydrophobicity despite the absence of endcapping. |
| GROM-SIL 80 ODS-7 pH | Polymer-coated, pH-stable phase with extremely high carbon-content. |
GROM SIL C8 phases
| GROM-SIL 100 Octyl-1 B | Base-deactivated phase with enhanced selectivity. |
| GROM-SIL 100 Octyl-2 AB | Acid- and base-deactivated phase specially suitable for the separation of acids and bases. |
| GROM-SIL 120 Octyl-3 BA | Tailor-made for the separation of basic molecules, monomeric bonding of alkyl silanes with differing chain lengths. |
| GROM-SIL 120 Octyl-4 FE | Fully endcapped octyl phase, “monomerically bound” and thus highly versatile. |
| GROM-SIL 120 Octyl-5 CP | Octyl-phase on silicone-encapsulated particles, particularly long lived. |
| GROM-SIL 120 Octyl-6 MB | Densely coated C8 phase, endcapped, for acidic and basic compounds. |
