LC epsilon Detector
The epsilon is a revolutionary new family of instruments that has been designed to allow the user great flexibility in choosing a particular configuration. The main features of the LC epsilon are:
- Optically isolated circuitry for noise reduction
- 100 pA to 5 mA gain ranges
- 24-bit data resolution
- Up to 4-channel EC capability
- Provision for inputs from two external LC detectors
- Pulsed amperometric detection (PAD)
- Remote control of BASi pumps
- Upgradable to perform cyclic voltammetry
- Upgradable over the Internet
- Built-in data processing
- Has both analog and digital filtering for maximum noise reduction.

Once you have selected your method of payment you will need to configure the epsilon Detector for your particular application. Using the price list select one, two, or four channels. You will then need to select the appropriate flow cell to match your initial channel selection. You may also add various options such as an injection valve, column temperature control, and columns. ChromGraph data reduction and control software is included with the LC epsilon Detector.
