Ultra-high speed separation of food additives in a soft drink
14 Mar 2022In this application note, the usefulness of an X-PressPak V-C (2.0 mm I.D. x 50 mm L.) packed with 2 μm diameter packing material for the ultra-high speed separation of food additives was examined. A 4λ−UV detector was used for the simultaneous monitoring of these additives at four different wavelengths. The results were examined to determine whether the performance of the column and chromatography system exceeds those of conventional HPLC.

LC-4000 Series Integrated HPLC and UHPLC Systems
JASCO (USA)The LC-4000 Series is the latest in a long history of innovative HPLC systems developed by JASCO reaching all the way back to the start of commercial HPLC in the early 1970s. The concept of the integrated LC-4000 series HPLC provides key separation platforms at 50MPa, 70MPa and 130MPa which correspond to conventional HPLC, the increasingly popular Rapid Analysis (RHPLC) and sub 2um UHPLC, respectively. Each platform is supplied with a dedicated pump and autosampler matched to the operating pressure and all three platforms share common detectors optimized for high-speed 100Hz acquisition and the narrow peak shapes common to both RHPLC and UHPLC. Features 300mm wide footprint Each system component is completely stackable into a modest height The system is fully integrated with complete system monitoring All user replaceable components are accessible through the front panel Vertical leak/drain system to channel away solvent Integrated earthquake securing option All detectors include 100Hz acquistion with interchangeable flowcells Preparative HPLC Systems The LC-4000 preparative HPLC systems includes three platform options Up to 20mL/min for columns up to 21.2mm ID Up to 50mL/min for columns up to 3cm ID Up to 120mL/min for columns up to 5cm ID
