Ensures that sufficient data is captured when using the new ultra high pressure liquid chromatography method (UHPLC), gives the user the opportunity to record up to 100 points in a ten-second peak
Beta-Ram, the on-line radioactivity detector from LabLogic Systems, ensures that sufficient data is captured when using the new ultra high pressure liquid chromatography method (UHPLC).
The shorter run times achieved by UHPLC are made possible by faster elution of the sample, which produces peak widths of around ten seconds, compared with typically 60 seconds or more using conventional HPLC.
With an output of ten data points per second, Beta-Ram gives the user the opportunity to record up to 100 points in a ten-second peak.
In the same circumstances, a similar detector currently on the market can capture only ten data points, resulting in reduced accuracy when calculating peak area.
Beta-Ram is the most sensitive on-line radioactivity detector available, claims Lablogic.
It uses high specification one inch photomultiplier tubes to maximise signal-to-noise ratios for ultra-low backgrounds (less than 4cpm for tritium and less than 1cpm for carbon-14) combined with optimum counting efficiency (more than 60% and more than 90% respectively).
At 348x330mm (horizontal) or 152x330mm (vertical), it also has the smallest footprint.
Beta-Ram was recently used successfully in comparisons of UHPLC and conventional LC systems detecting radio-labelled markers in routine work flow samples for matching with MS/MS data.
