Aurius Series
With an optical bandwidth of 4nm and superb stability, accuracy and precision these very easy to use instruments are ideal general purpose spectrophotometers. Excellent for routine and quality control laboratories, they offer a wide range of quantitative techniques with wavelength scanning as an option. Both UV Visible and Visible versions are available with full validation procedures.
Super Aurius Series
The Super Aurius instruments are unique for their very high performance scanning, with derivatives, overlay, extended analytical power and multi-cell Kinetics. They cover the full 190-1100 nm wavelength range with a narrow 1.8 nm optical bandwidth. With straylight of 0.01%, wavelength precision of 0.1 nm and baseline stability of better than ±0.001 A/hr, the most demanding analytical work may be undertaken.
Performance with Convenience
The ease of operation makes even complex tasks simple. An exceptional range of software and accessories makes the Aurius and Super Aurius instruments superb multi-user instruments, ideal for multi-discipline laboratories.
Six Screen Width Viewing
All scans, curves and data produced by the spectrophotometers may be scrolled across the screen providing a very wide 6 screen widths - 550 mm - of viewing of extended displays.
Absorbance Accuracy
The low straylight of the instruments, less than 0.01%, allows a measurement of 3 Absorbance units to be made with an error close to 1%.
This performance should be compared with errors of 26%, 10% and 6% which result from straylight of 0.5%, 0.1% and 0.05% respectively for the same measurement.
Ease of Operation
The large screen with contrast control, displays menus and prompts for all applications. All curves, scans and data displayed on screen may be reprocessed before printing.
Software Enhancement by E-SEF
E-SEF - Encoded Software Enhancement Facility - is an important new Cecil design feature. Optional software modules are enabled by entering correctly allocated encoded numbers. These numbers can be provided by telephone, fax or E-Mail. Exact software requirements may therefore be tailored after instrument purchase without incurring delay before use.
Integral Printer
The integral printer versions provide hard copy of spectra, curves and time course plots, as well as timed and dated reports of all experiments. An external, Epson compatible, printer may be used providing large size high quality plots and documentation of quantitative assays.
Accurate Quantification
For optimum accuracy when measuring concentration, a calibration curve may be fitted to a series of up to 30 standards or replicates. Accuracy is improved over using a single known concentration or entering a factor.
Concentration Curve Fitting
When concentration is not linearly related to Absorbance a quadratic or cubic curve may be fitted to up to 30 standards or replicates, with or without an intercept. A straight line may be fitted when a linear relationship exists. Curves are displayed with data for each standard documented.
Editing of Data
Outlier standard data points revealed by the initial fit may be deleted or replaced for a new fit. Up to 30 curves may be stored security protected.
Wavelength Scanning
Wavelength scanning from 190-1,100 nm is standard on Super Aurius instruments with a narrow 1.8 nm optical bandwidth. For the Aurius range scanning software is optional with a 4nm optical bandwidth.
Scans at up to 4000 nm/min are displayed with peaks and valleys tabulated and scans of up to 6 screen widths may be viewed by scrolling. Spectra may be printed on either the integral printer, as shown below, or an external printer.
The Super Aurius range offers in addition:-Derivative spectra, spectral storage and overlayed spectra and time plot as standard.
Cell and Wavelength Programming
A cell program software module enables up to 4, 6 or 8 cells to be programmed with the appropriate cell changers. Programming of up to 10 different wavelengths is also provided by the wavelength program software module.
A combined cell and wavelength program may be run for up to 8 cells and 10 wavelengths. A cell and wavelength program may be used for calculations using complex formulae entered using the Assay program, with automatic formatting and printout of results.
