Performance Validation
A full validation software module is available on all instruments
and may be released by E-SEF.
A range of Pharmacopoeia (EP/BP/USP) tests are provided for laboratories
subject to regulatory control or following good G.L.P. A selection
of these tests is shown here.
Test procedures are also provided using filters traceable to national
standards with certificates issued by Cecil Instruments. |

Absorbance Accuracy
The Pharmacopoeia (EP/BP) test for absorbance accuracy uses
a 60mg/L solution of Potassium Dichromate in a 10mm pathlength
cuvette. The results of a test are shown here. |

Straylight
The Pharmacopoeia (EP/BP) test for straylight is shown. This
uses a 1.2% W/V solution of Potassium Chloride in water measured
against water in the reference beam.
The more widely accepted ASTMS tests at 200nm and 340nm are
also available. |

Optical Bandwidth
An automatic procedure is provided which measures the half
height width of the narrow deuterium emission line at 656.1nm.

Micro-Sipette Sampling
Samples of 300µl or less may be measured with very low cross
contamination using the Micro-Sipette system.
All measurements are made in the same cell enhancing accuracy.
The pump operates under the control of the instruments microprocessor
system and is mounted within the sample compartment.
Ultra-Micro Sampling
Valuable biological samples prepared with costly reagents may be
measured using a special ultra-microcell and holder. Samples of
50µl or less may be accurately measured. |
| |
|
|
Spectrofluorescence
Fluorescence measurements are made using the CE 572 accessory.
Excitation radiation may be scanned and sensitivity maximised using
the 4nm bandwidth of the CE 9500. |

Automatic Sample Changers
A full range of auto sample changers is available for sample and
reference cells with the option of water or thermoelectric temperature
control. |
|
 |
| |
|
|
Sample Temperature Control
Thermoelectric control is available for single holders and multi
cell holders and includes temperature programming. Operation is
via the spectrophotometer's control panel. |
