Control and Data Evaluation

Provided by PeakNet 6 or Chromeleon software; communication with the detector is via the DX-LAN interface

Cell Body

PEEK or stainless steel

Volume and Optical Path Length

PEEK cell: 13 µL volume; 10 mm (0.394 in) path length

Stainless steel cell: 13 µL volume; 10 mm (0.394 in) path length

Maximum Operating Pressure

PEEK cell: 2 MPa (300 psi)

Stainless steel cell: 3 MPa (500 psi)

Chemical Compatibility

-Do not use bases stronger than 0.1 M; they will etch the silica windows of the flow cells.

-Do not use normal phase or chlorinated solvents with the PEEK flow cell; they will damage the cell.

-Do not use high pH salts with the stainless steel flow cell; they will cause corrosion, contamination, and metal leaching.
