Novel High Performance High Speed Liquid Chromatography |
|
|||
For high-speed, high-resolution HPLC two types of uniformly spherical 1,5 µm GROM-Sil ODS-2 FE particles are available, either fully porous microspheres (pore size 100 Å /particle size 1.5 ± 0.3 µm, specific surface area of 200 m 2 /g) or monodisperse non-porous beads (particle size 1.5 ± 0.05 µm, specific surface area of 2.1 m 2 /g). Both are fully end-capped C18 phases meeting all the requirements of the most advanced high performance liquid chromatography applications. For instance, in a minimum of analysis time, they perform excellent separations of nucleotides, peptides, proteins, pharmaceuticals, etc. | |||
|
|||
Even after more than 2 500 injections,both types of columns packed with either 1.5 µm porous-or 1.5 µm non-porous particles still show excellent physical and chemical stability (even in 0.1%TFA containing eluents).There is no change in retention time and practically no increase in pressure drop and peak asymmetry over the life of the column. These NovoGROM high speed columns of only 33 mm length provide up to 10 000 plates,and thus in most cases have a resolution nearly identical to that which is typically found for standard analytical HPLC columns. |
Column lifetime |
|
Employing NovoGROM high speed columns you gain tremendously in | |
Speed: | analysis time in seconds or minutes, with up to 90%increase in sample throughput |
Low solvents consumption: | saves on purchase and disposal costs, decreasing solvent consumption brings improved environmental compatibility |
Decreased diffusion: | smaller peak volume and less band broadening, i.e.,improved sensitivity |
