SolventTrak^TM is a solvent conservation system designed to recycle uncontaminated solvents used in isocratic HPLC processes. In most systems, a high percentage of the mobile phase can be recycled and reused which saves money by reducing solvent consumption and disposal costs.

What Makes SolventTrak Reliably Accurate?
SolventTrak automatically detects eluting peaks and diverts them to waste while sending the clean, uncontaminated solvent back to the reservoir for recycling.

Traditional recycling systems use a fixed voltage level (or threshold above baseline) which must be exceeded before peaks can be detected. If the baseline changes, new settings must be applied or contaminants may be recycled instead of sent to waste. Conversely, pure solvent may be sent to waste rather than being recycled.

• SolventTrak incorporates a unique integration algorithm to accurately detect peaks in the eluent so that contaminants are eliminated even if chromatography system conditions cause the baseline to drift up or down.
  
  
• Solvents recycled with SolventTrak are cleaner and can be used longer.
  
  
• Each SolventTrak is calibrated and certified to an NIST traceable standard and arrives with a Certification of Validation

How Does SolventTrak Work?
The signal from any HPLC detector is connected to SolventTrak, which monitors and continuously displays the voltage level on a large, highly readable LCD panel located on the front of the instrument. The signal, if desired, can be connected directly to a chromatography data system or integrator.

SolventTrak peak detection sensitivity may be adjusted by touch-sensitive controls which change familiar peak width and peak threshold parameters, similar to those found on most integrators and data systems.

How Does SolventTrak Further Enhance Purity?
When a peak is identified an additional delay time may be set to allow for volume between the detector and the valve. This further enhances the accuracy and purity of the recycling. An LCD indicator and a switchable audible alarm alert the operator that a peak has been detected.

A reliable and inert electrically actuated solvent diverter valve automatically switches mobile phase to waste when peaks are detected. The valve may also be intentionally switched via TTL or contact closure by actuating that command on the front panel keypad if and when required.

Important Special Features
SolventTrak can place a tick mark (peak marker) on the output signal to show exactly where peaks have been detected and sent to waste. This is very useful during initial system set-up and significantly more important during system testing and validation. Sophisticated circuitry permits the signal to be zeroed automatically via a contact closure or manually using front-panel touch controls. SolventTrak complies with CE requirements. Power requirements are 95 to 250 VAC self switching

SolventTrak Saves
With the high cost of solvent and solvent disposal, a routine analytical HPLC system can recover the cost of SolventTrak in 60 to 90 days. Then continue to save with SolventTrak on: Solvent Purchases...Disposal Costs...and Solvent Preparation Time.

Optional Clean-up Kit
Automated system clean-up with wash solvent. Includes 2nd diverter valve and mounting bracket.
