Villa Labeco ITP-CZE EA 202M electrophoretic analyser

The modular arrangement of this analyser enables its application with several electrophoretic modes of operation e.g.

• isotachophoresis (ITP)
• capillary zone electrophoresis (CZE)
• or 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 which employ contactless conductivity detectors (less sensitivity and a higher price but with increased lifetimes).

Columns for the first and second dimension are named ‘pre-separation' and ‘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.
