High Performance Micro Flow Through Conductivity Monitor
  
An indispensable tool for Ion Exchange separations of proteins or ION
chromotography

Monitor uses ultra stable electronics including electronic zero suppression
and automatic temprature control combined with ultra low volume flow cell

You can now optimize the salt gradient separation of proteins by
continuously monitoring the conductivity of your ion exchange buffer
during your run.

Build your own modular ion chromatography system

Features
*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.

*Ultrastable solid state electronics.  The conductivity monitor uses
the
 latest state of the art integrated circuitry, giving baseline stability,
 signal to noise ratio and overall performance comparable to units costing
 many times as much.

*Electronic zero suppression.  The conductivity monitor can be adjusted
 from 0 to 200% zero suppression using a panel mounted precision 10 turn
 potentiometer.

*Broad conductivity ranges.  The conductivity monitor has 3 front panel
 selectable conductivity ranges:  0 to 50, 0 to 500, and 0 to 5000
 micromhos/cm.

*Low volume flow cell.  The conductivity cell has an internal volume
of less
 than 20 microliters.

*Positive temperature control.  The conductivity monitor incorporates a
 thermister in the flow cell for positive temperature compensation.

*Ideal for low cost methods development.  The conductivity monitor
is ideal
 for low cost chromatography methods development for a wide variety of samples
 using different columns.

*Compatible with all popular protein chromatography systems.  Directly
 adaptable to Pharmacia r, Biorad r, and Waters r, protein separation systems.
 Specify manufacturer and model number on purchase order to get exact
compatibility.

*High Performance at low cost.  The Acu I monitor has features such
as zero
 suppression, which even some of the much more expensive units don't have,
 at a fraction of the cost.

Application Areas

*Eliminate guesswork in protein separations.  Determine exact eluent
 compositions at the point that each protein elutes form the LC column.

*Optimize Desalting.  Determine optimal cutoff point of separation
of salt
 from protein in gel filtration.

*Minimize regeneration time of ion exchange columns.  Minimize the
time to
 equilibrate an ion exchange column after a separation completion.

*Verify column packing efficiency.  Determine LC column packing
efficiency
 before proceeding with separation run.
