CAPEL-103R/103RT , their upgraded automated version CAPEL-104/104T
and CAPEL-105 are high-performance capillary electrophoresis instruments,
equipped with a photometric detector. The CAPEL-103R/103RT analyzers
have manually controlled samplers with 4 inlet and 2 outlet positions,
and CAPEL-104/104T/105 have autosamplers with 10 inlet and 10 outlet
positions. The samples, rinsing and buffer solution are fed automatically
according to a preset program. The autosampler in CAPEL-104/104T/105
increases the number of analyzed samples to 7, and the customized
software makes the analysis fully automated. All instruments are
equipped with a reversible polarity voltage supply units and with
a customized report outputs (hard copy and file). The CAPEL-103RT/104T/105
have a liquid cooling system with temperature control for capillary
cooling.

and operation features |
Detectors
CAPEL-103R / -103RT, -104/ -104T with one wavelength UV-detector
have a working wavelength of 254 nm. CAPEL-105 is equipped with
variable wavelength UV-detector, with a wavelength range from
190 to 380 nm.
Vials
Standard 1.5 mL vials are used, with a minimal sample volume 100
µL.
Injection modes
Injection modes employ controlled pressure profile injection with
variable peak pressure, with programmable peak pressure ranging
from 0 to 30 mbar. The injection time can be programmed, too.
Electrophoresis power
Voltage range can be set from 1 to 25 kV
(manually reversible polarity)
Current settings may be varied from 0 to 200 mA.
System control
Membrane keyboard
Four string 20 characters and 30 string 16 characters LCDs in
Capel-103R/103RT and Capel-104/104T/105, respectively.
Data acquisition and processing system are based on a standard
PC and Chrom&Spec® software with MSWindows® user interface.
