Shimadzu has launched the Prominence UFLC system and Shim-pack XR-ODS columns, for a practical approach to conserving acetonitrile.
Faced with a worldwide shortage of acetonitrile (ACN), labs are seeking ways to reduce consumption of this common HPLC solvent.
To this end, Shimadzu Scientific Instruments' Prominence UFLC/UFLCXR systems and Shim-pack XR-ODS UFLC columns minimise ACN consumption through high-speed analysis, yet retain the flexibility of conventional analysis.
Engineered for low carryover, the valves on the Prominence autosamplers require little or no additional rinsing after injection.
The injection cycle time of the autosampler is 10 seconds, further reducing mobile-phase consumption.
For operation under pressures up to 66MPa, UFLCXR permits the substitution of methanol for ACN.
Shim-pack XR-ODS columns enable users to shorten analysis time and substantially reduce ACN consumption without high pressures (<30MPa) by using a 2.2mm particle size.
Used with the Prominence UFLC system, a Shim-pack column uses only 2.3ml of ACN for analysis of alkylphenones, compared to 10.5ml with a 5 mm column.
In addition to reduced acetonitrile usage, analysis is five times faster with the use of the Shim-pack XR-ODS, and specialised high-pressure hardware is not required for operation.
