FEATURES

[i]Precision Temperature Control-Modular Flexibility[/i]  The system is easy to use by control panel operation, or by using the sophisticated Cecil PowerStream software for data acquisition, processing and reporting. Full system control is also provided by the workstation equipped with PowerStream.    The modularity of the system enables its configuration to be changed with ease, for instance for use with a UV/Visible detector. Modules may readily be replaced, to reduce down-time, should the need arise.    The system is easy to use by control panel operation, or by using the sophisticated Cecil PowerStream software for data acquisition, processing and reporting.

Electronic feedback control virtually eliminates pulsing without using mechanical damping.    [i]Column Oven[/i]  The very precisely temperature controlled oven accommodates Anion and Cation columns and precolumns, as well as a background suppressor cartridge with its over pressure protection valve. Close coupling to the detector provides high stability, low noise and low dispersion.    [i]Leak Detector[/i]  A specially designed leak detection system is accommodated within the cell oven enclosure. The detection system may be used to shutdown the system if a leak is detected in the enclosure.  [i]  PowerStream Software[/i]  This software, developed by Cecil Instruments, provides system control and superb data processing, manipulation and reporting with truly unrivalled ease.    [i]Detector – Advanced Design[/i]  The CE 4710 Conductivity Detector is an entirely new design from Cecil Instruments providing performance of the very highest order due to its exceptionally low noise and unrivalled baseline stability. To achieve this standard of performance a very low volume, 0.5µL, conductivity cell has been designed and is operated in a precisely thermostatted aluminium oven enclosure. A specially designed, low dispersion, heat exchanger, is also mounted in the cell enclosure preceding the detector cell. The exchanger stabilises the temperature of the mobile phase entering the cell. With the enclosed system controlled to better than ±0.01ºC superb performance is always available. Autozero and auto-range facilities are provided to ensure convenience of operation. Built-in diagnostics aids instrument evaluation and fault finding. The temperature controlled cell and heat exchanger enclosure is conveniently accessed from the side of the detector module, as shown in the photograph.    [i]Detector Features[/i]  [list]  [*] Full control by PowerStream software workstation  [*] Keypad and LCD interface, for local operation, when required  [*] Large memory for analytical methods  [*] Autozero for operator convenience  [*] Operator selectable cell temperature; default 35ºC  [*] Leak detection system shutdown. Important for unattended operation.  [*] Self diagnostics to confirm instrument function  [*] Mounting facility for Rheodyne injection valve  [*] Calculation of detector cell constant not required  [*] Polarity switching  [/list]    Sensitivity for the measurement of anions is greatly improved by reducing the conductivity of the eluent post column. An optional Anion Membrane Suppressor - SAMS ™ - is available which is mounted in the column oven, in series with and after the analytical column. The suppressor may be used continuously and is regenerated by a Continuous Anion Regeneration System - CARS ™ - , which pumps the regeneration fluid through the post column suppressor cartridge. The suppressed solvent background conductivity leads to reduced drift and noise and therefore higher sensitivity for measurements is available.  Close coupling of the detector to the oven is important in eliminating the effects of ambient temperature fluctuation on results. The couplers can be seen on the side of the detector. The cell compartment thermostatted enclosure is shown in the lower photograph, with the side cover removed for easy access.
