| The new "Olis
Short Pathlength Titration Accessory"
supports use of cuvettes of arbitrary
pathlength thereby supporting far UV
CD applications. All mixing is accomplished
by computerized infusion/withdrawal
cycles from the storage syringe to the
measuring cell.
Our design
- assembled by a team of experienced
mixers (stopped-flow specialists)
-- allows you to use highest quality
cylindrical cuvettes with pathlengths
of arbitrary length and diameter,
making it ideal for all spectral ranges
and cuvette pathlengths.
Mixing is complete.
Delay times to wait for equilibrium
are user-selectable.
Volumes are based on cuvette pathlength.
Dilution ratio of sample and titrant
are arbitrary.
There are no 'overflow' issues; sample
is 'mixed and stored' in an external
syringe until time of optical measurement;
and volume to be measured is precisely
what is needed to fill cuvette (any
'overflow' remains in mixing/storage
syringe).
In-line pH microelectrode can be positioned
within flow line from storage syringe
to sample cell. The sample is in the
light path only when measurements
are made
