The CE 9500 offers variable optical bandwidth from 0.5mm to 4mm. This range covers all the more exacting applications where either high optical resolution or maximum energy throughput is required.

Up to 100 sets of instrument parameters, including concentration curves may be stored, security code protected. When recalled, instrument parameters are automatically set, avoiding errors.

A full Alpha Numeric facility is provided for formula entry and documentation for GLP. Assay formula entry with Assay Program is rapid and calculations using many wavelengths may be made at high speed with fully documented results.

Up to four or six cells are automatically measured with all reaction curves displayed on screen. Each curve may be selected for processing with the results of regression analysis printed.

Assays are provided using either two or three wavelengths. A wine colour assay is provided. Assays for Warburg and Christian, Lowry, Bradford, Biuret and BCA methods are also available.

Band areas with correction for sloping background absorption are readily quantified, with all details and construction displayed. Band areas may also be computed for derivative spectra to facilitate difficult quantification.

Using the various cell changers, measurements may be made on up to 4, 6 or 8 cells at a single wavelength with cycle time and number of cycles entered by the operator. A cell and wavelength program may be combined.

Measurements may be programmed for 10 different operator selected wavelengths with the cycle time and number of cycles selected by the operator. A wavelength and cell program may be combined.
Scanning

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.

Use of the display scrolling facility enhances the effective screen size and enables spectra and data up to 550mm wide, 6 screen widths, to be viewed. The last eight scans are automatically retained for recall by entering their scan sequence number and may be reprocessed, overlayed or transferred to protected memory for future recall.

Up to six scans, including stored scans, may be overlayed, with or without offsets for convenient comparisons or further manipulation.

New wavelength scans or scans from store may be presented on screen and the difference spectra produced. The scans may be normalised enabling spectral stripping to reveal impurities or additives.

Derivative spectra, up to sixth 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.

Up to 100 spectra may be stored in 10 safe memory banks for future recall. Each spectrum is automatically allocated a recall number, when stored, and may be security code protected against tamper or deletion.

Automatic scans, single or repeat may be made of a cell program of up to 4, 6 or 8 cells. A programmed sequence of scans may also be made of a single sample.

Changing samples or flows may be examined and displayed by making a time course plot. Data may be reprocessed and stored, security code protected, with an automatically assigned recall number.
Sampling

As well as 10mm cells and flowcells, holders are available for rectangular and cylindrical cells up to 100mm pathlength. A microsampling system measures to 50µl or below. Third party nano cells may also be used.

A turbid sample optical system enables the measurement of heavily scattering samples, which would otherwise be difficult or impossible to measure. 10mm cells, films or solid samples may be measured.

Automatic changers are available for 4, 6 or 8 cells, providing rapid sample changing or the facility for full programming.

Samples down to 300 microlitres may be measured in a 10mm cell. Sampling is under control of the instrument's microprocessor system. Samples may be saved or pumped to waste.

Water and thermoelectric temperature control are available for single cells and automatic cell changers. Temperature is set from the control panel and displayed on the screen.

Automatic batch sampling for up to 100 samples is available. The pump fits within the sample compartment and volume etc is set from the control panel and displayed on screen. Batch number entry is provided.

Versions of the instruments fitted with a special cell compartment with piping port, are available for dissolution testing using Cecil TD software and a PC. Six and eight cell changers are available.

Special accessories enable specular reflectance measurements to be made. Both fixed angle and variable angle reflectance accessories are available. The latter is particularly useful for film thickness measurements.

Using the fluorescence accessory quantitative assays are possible. When required the excitation wavelength may be scanned. A gel scanner enables 100mm gels and films to be measured.
