The Super Aurius instruments are unique for their very high performance scanning, with derivatives, overlay, extended analytical power and multi-cell Kinetics. They...

AURIUS - The Choice - SUPER AURIUS SIX SCREEN WIDTH VIEWING Accurate Quantification FAST : EASY TO USE : POWERFUL SOFTWARE For optimum accuracy when measuring concentration, a calibration line may be fitted to a series of up to 30 standards or replicates. Accuracy is improved over using a single known concentration. FAST PROGRAM ANY ASSAY Concentration Curve Fitting When concentration is not linearly related to absorbance a quadratic or cubic curve FOR MORE POWER - PERFORMANCE FAST DATA TRANSFER TO PC may be fitted to up to 30 standards or replicates, with or without an intercept. A straight...

SIX SCREEN WIDTH VIE FAST : EASY TO USE : AST SCANNING NOTE: This column applies only to Super Aurius. Scan is an option on the Aurius range. Wavelength Scan Scans at up to 4000nm/min are presented on screen or printed with all peaks annotated with wavelength and absorbance. Tables are also presented listing all peaks and troughs with values. Derivative Spectra Derivative spectra are readily produced, with selectable smoothing, either alone or superimposed on the fundamental, with or without an offset. Scaling is automatic, with all peaks and troughs quantified. Overlayed Spectra Up to six scans,...

: POWERFUL SOFTW SOFTWARE ASSAY SYSTEM FUNCTIONS PERFORMANCE DataStream - Fast Data Transfer and Control Cecil DataStream software provides fast transfer of all data to a PC for incorporation into a spread sheet or mathematical package of the users choice. Fast and easy to use. Spectrophotometers may also be controled from the PC. DATION :and Calibration Self Test GLP An automatic test procedure, at switch-on, checks all instrument functions and calibrates wavelength against a deuterium lamp emission line. Performance is confirmed by a timed and dated report including instrument serial number....
