Full Spectrum™ Multi-Color Fluorescence Reference Standard is a highly uniform microbead product that fluoresces over the visible spectrum to provide reference positions for initial daily QC or instrument set-up.
As part of a QC program, fluorophore-labeled microspheres offer a convenient means to check general instrument status and monitor stability over time. When beads are run, the channel values for pertinent fluorescence detectors are recorded, and data are monitored to identify outliers and trends. This type of check can alert the user to problems with the optical and fluidic systems (e.g. diminishing laser power or obstruction/leakage) and the effect of environmental factors, such as temperature, humidity, and vibration on instrument performance.
As a tool for instrument set-up, a reference peak may be positioned for each detector to achieve initial instrument settings.
