Dual Wavelength UV Detector: CE 4200

The Adept CE 4200 is a detector of the highest specification and versatility, covering the range 190 to 700nm, with an optical bandwidth of approximately 8nm. Operation is by a keypad and 4 line LCD display of menus, prompts, parameters, wavelength, absorbance etc. It may also form part of any system controlled by PowerStream software.

Dual wavelength operation allows two wavelengths to be monitored simultaneously with their ratio also being available. Full programming using up to six wavelengths is also possible from the control panel.

Noise and drift performance are of the very highest order, ±0.35 x 10-5A peak to peak, and ±3 x 10-5A/h respectively, with straylight less than 0.02%. Up to 30 methods may be created and stored password protected, ensuring reproducible conditions when recalled. An auto switch-on programme saves operator time during warm-up.

Variable Wavelength UV Detector: CE 4201

The Adept CE 4201 detector is designed to monitor any single wavelength in the 190-700nm range. Optical bandwidth is approximately 8nm and stray light is less than 0.02%.

Calibration and test are automatic at switch-on. Software for validation procedures is available. Flowcells may be changed easily and without alignment adjustments and the Deuterium lamp is guaranteed for 1500 hours or 1 year, and is fitted with an hours counter.

Noise and drift performance are of a very high order. <±1 x 10-5A peak to peak and <±1 x 10-4A/h respectively. An automatic switch-on program is provided to save operator time during warm-up.

Refractive Index Detector: CE 4700

The Adept CE 4700 differential refractive index detector is suitable for compounds which show no active absorption in the UV region such as sugars or polymers. The highly stable detector is operated by a keypad and 2 x 16 character LCD display.

The flowcell is temperature controlled and drift and noise are of a low order.

A built-in solenoid valve enables the reference cell to be conveniently flushed or filled. The unit is supplied with a column mounting panel and cover.

The signal output may be processed by PowerStream or connected to a recorder or integrator.

Fluorescence Detector: CE 4500

The CE 4500 dual monochromator fluorescence detector is fully programmable, each monochromator covers the wavelength range 200-600nm and uses an adjustable frequency Xenon lamp for its source.

The wavelength range of the emission monochromator may be extended to 800nm by using a special photomultiplier.

The sensitivity is excellent and the module forms part of the normal system stack.

Electrochemical Detector: CE 4720

This electrochemical detector is a new addition to the Cecil HPLC range. It has excellent performance and uses a glassy carbon active electrode to form part of a flowcell with a very low, 1.2µL, volume. Other active electrodes may be used.

The cell assembly is mounted in a Faraday cage, with easy access, to protect it from electromagnetic interference and its enclosure also protects it from temperature fluctuations.
