Electrophoretic Analyser
Electrophoretic Analyser EA 202M with 2 columns employing contactless conductivity detectors.
The modular arrangement of this analyser enables its application with several electrophoretic modes of operation as follows:
- Isotachophoresis (ITP)
- Capillary zone electrophoresis (CZE)
- The highly efficient combination of ITP - CZE
Users can choose to work with traditional columns (Employing contact conductivity detectors) or alternatively take advantage of our updated columns that employ contactless conductivity detectors (Less sensitivity and a higher price but with increased lifetimes).
Columns for the first and second dimension are named ˇ®pre-separation' and ˇ®analytical' columns respectively.
Pre-separation columns employ FEP capillaries (I. D 0.8 mm) and are available in several lengths (See Acessories).
Each analytical column is equipped with an adapter (SMA or 2 mm JM) for connection with optical fibres to the UV detection facility.
The standard package includes an in-built UV detector with 4 wavelengths, however a variable wavelength or DAD UV detector can be purchased as an optional extra.
The standard and most basic version of the instrument is equipped with an ITP injection valve, 2 columns and modules for manual filling of electrolytes.
