Dual Wavelength UV Detector CE4200 Dual Wavelength UV Detector

The Adept CE4200 is a detector of the highest specification and versatility covering the range 190-700nm 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 0.3 x 10-4A 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 CE4201 Variable Wavelength UV Detector
The Adept CE4201 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/hour respectively. An automatic switch-on program is provided to save operator time during warm-up.

 

 


Refractive Index Detector CE4700 Refractive Index Detector
The Adept CE4700 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 conveniently be 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.

 

 


Conductivity Detector CE4710 Conductivity Detector
The CE4710 conductivity detector converts an Adept HPLC system into an ion chromatograph. Quantification of anions, cations, metals, organic acids and surfactants is possible with solid phase chemical suppression (SPCS) down to ppb levels; without SPCS down to the ppm range.

The 0.5L cell is temperature controlled to 0.05C in its enclosure.

A solid phase chemical suppresser module CE4715 is available using two cartridges, one provides suppression while the other is equilibrated or replaced.

 


Fluorescence Detectors CE4500 / CE4501 Fluorescence Detectors
The CE4500 shown here is a dual monochromator fully programmable detector, each monochromator covering the range 200-600nm, using an adjustable frequency Xenon lamp.

Flowcells of 4, 8 and 24L irradiated volumes are available. The detection sensitivity is better than 100fg Anthracene in methanol using a 24L flowcell.

The CE4501 is a filter detector for use where a lower cost is required. The lamp flash frequency is adjustable and the same 4, 8 and 24uL flowcells may be used. Sensitivity is better than 0.2pg Anthracene in methanol, using excitation at 254nm and a 24L flowcell.
