Internal Amplifier: Internal amplifier converts conductivity measurement to
millivolt output which is readable on pH/mv meter or strip chart recorder
Output Signal: 0 to +/- 2,000 millivolt- use with pH/mv meter or strip chart recorder
Description: conductivity monitor complete with flow through cell,
preamplifier, and connector cable to pH/millivolt meter or strip chart recorder.
Features:
Collect protein fractions on basis of conductivity - increase accuracy and
reproducibility of LC protein separations.
Monitor anions and cations in ion chromatography
Low dead volume. Conductivity flow cell has an internal volume of less
than 80 microliters.
Comes complete with amplifier module for direct connection to pH/mv meter
or strip chart recorder
Attaches directly to LC or HPLC plumbing using 1/4-28 fittings.
Continuous conductivity recording. Conductivity monitor attaches directly
to strip chart recorder for recording conductivity profile. Can also be
used with your pH meter.
Applications: Salt gradient elution of proteins,
Column LC, and Ion chromatography
Unique adavantages of micro flow through electrodes
Low volume flow through systems. All flow through ion electrodes
have internal volumes less than 50 microliters (except for pO2
which has a volume of 150 ul).
Wide flow range. The standard flow through cells have a
flow range of 0 to 25 ml/min. Flow cells are also available for
flow rates up to 500 ml/min.
Rapid response. Response time for all the flow through
electrodes is less than 20 seconds for a 50% increase in the
parameter being monitored.
Low detection limit. Micro flow through ion electrodes
will typically measure below 1 ppm, while some ion electrodes
like the sodium electrode will measure down to 0.02 ppm (1
micro Molar). Conductivity micro flow through electrode
can detect down to 1 microsiemen.
Compatible with all laboratory pH meters. The micro flow
through electrodes are compatible with all major brand pH
meters including Orion(R), Beckman(R) Corning(R), Fisher(R),
and Radiometer(R). Specify meter when ordering.
Use chart recorder or PC for continuous recording of concentration vs. time.
The recorder output from the pH/mV meter which is used
with the pH and ion electrodes can be input into a standard strip
chart recorder or PC with an A to D converter. The pO2 and
conductivity flow through electrodes can be fed directly into a
chart recorder or PC.
Use with silastic or other flexible tubing. Electrodes come
with miniature hose barb end fitting. Just slip the silastic
or other tubing over the hose barb fitting for a leak free
connection.
Use with HPLC fittings. The micro flow through electrodes
also come with 1/4-28 chromatography fittings and can be
plumbed directly to an HPLC system using fluoropolymer or PEEK
tubing.
Indispensable tool for LC gradient elution of proteins.
The conductivity monitor is ideally suited for continuous monitoring
of salt gradients in ion exchange, reverse phase, hydrophobic
interaction, and hydroxylapetite separations.
All biocompatible components. All electrode components are made
of glass, fluoropolymer, acrylic, and epoxy and are completely
compatible with biological solutions containing proteins etc.
Autoclavable Autoclavable micro flow through electrodes are
available at extra cost. Specify when ordering.
Ideal for organ perfusion studies. The micro flow through
electrodes for pH, pO2, and pCO2 are ideally suited for perfusion
studies in liver, kidney, heart, lung, and other perfused organ
systems.
