16.3.3 VT-03 micro flow cell
The micro flow cell is assembled when it arrives. The force on the bolts is preset to 13 Ncm (“a
little bit beyond finger-tight”). Familiarize yourself with this force, because over-tightening of the
bolts strongly deteriorates the S/N ratio and eventually the cell itself. Also, be aware that the
black marks on both blocks should be in line.
16.3.3.1 Assembling the micro flow cell
The VT-03 micro flow cell has a 0.7-mm WE and is equipped with a 25-µm spacer. Older models
of the VT-03 micro are equipped with a metal centering ring, in which case both blocks (WE and
inlet block) have an edge/groove to accommodate the metal ring and are fixed in the metal ring to
align the inlet in the center of the WE.
