| The analytical NovoGROM HPLC column system is many-fold proven.
These columns can be connected to any HPLC system either conventionally via 1/16"
capillary, ferrules and screw fittings or dead volume free via the NovoGROM Quick
connectors. Standard dimensions are 3, 4 and 4.6 mm internal diameter and lengths of 2, 4,
6, 10, 12.5, 15, 20, 25 and 30 cm. Guard columns, i.e., protective precolumns, are
available in the lengths of 5, 10 and 20 mm. Columns may be filled as often as is required
in the economical refill service. Use of the 3 mm i.d. column results in a reduction in
the consumption of solvent of ca. 43% or 57% compared to the 4 mm and 4.6 mm i.d. columns
respectively. This not only reduces
costs, but is also active environmental protection.All NovoGROM columns can be supplied with any of the
stationary phases listed on GROM websites or in this GROM-HPLC catalogue
(see pages 12/13 and 144-151). Alternatively, they may also be packed by the GROM filling service with any stationary phase specified by the customer. |
The NovoGROM analytical column system is simple
to use and requires no tools („finger-tight"). It is practically dead volume
free, thus providing maximum resolution. NovoGROM stainless steel
columns are available in four versions:
- Standard packed column, complete with column heads, gaskets
and sieves
- Packed cartridge, with gaskets and sieves, ends sealed with
screw caps.
- Empty column, complete with column heads, gaskets and
sieves.
- Empty cartridge, with gaskets and sieves, ends sealed with
screw caps.
