Reference Beam Compensation (RBC) concept eliminates the effect of the short-term energy fluctuations often associated with the use of xenon flash lamps in spectrophotometry
The Libra S22 spectrophotometer, one of the new range of visible and UV-visible spectrophotometers from Biochrom, utilises its Reference Beam Compensation (RBC) concept to eliminate the effect of the short-term energy fluctuations often associated with the use of Xenon flash lamps in spectrophotometry.
The 'press-to-read' duty cycle only powers the lamp when it is needed for measurement, when stability is achieved instantaneously.
This means that measurements are accurate and highly reproducible, and the instrument combines excellent stability with extended lamp lifetime.
Other benefits are higher energy and lower stray light for measurements up to 3A and no need to change lamps mid-range.
Routines such as wavelength scan, kinetics and calibration curves are all available on the clear graphical display and may be printed out.
Instrument performance validation (IPV) is a self-diagnostic routine incorporated to aid GLP procedures.
The addition of Biochrom's Acquire software and a PC opens the door to more sophisticated applications and data manipulation.
The large sample compartment accommodates a wide range of accessories including long path length cells.
The Libra S21 offers a cost-effective visible-only instrument for those not requiring the UV region.
