Dual Wavelength UV Detector – CE4200
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
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
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
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 0.5µL cell is temperature controlled to ±0.05ºC
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
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 24µL irradiated volumes are available.
The detection sensitivity is better than 100fg Anthracene in methanol
using a 24µL 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 24µL flowcell.
