SolventTrak: HPLC Solvent Recycler for Purists
Is your Lab affected by Acetonitrile shortages?...Then ‘SolventTrak’ Solvent Recycler for Isocratic HPLC could solve your problem!
There is a significant world-wide shortage of Acetonitrile which has pushed up prices to extremely high levels. Due to this shortage we would like to introduce you to our SolventTrak solvent recycling system. Our sales of this product have dramatically increased in the past few months. The unit can save up to 90% of solvent in an isocratic system by diverting clean solvent (no peaks) back into the system. With payback times of just 4 weeks for many customers, solvent recycling is suddenly a hot topic, with major pharmaceutical companies buying multiple units at one time.
Recycling solvent saves money by reducing the amount of solvent required for a separation and also the disposal costs. It also has environmental benefits.

Pays for itself after just 2 months use!
SolventTrak is a solvent conservation system designed to recycle uncontaminated solvents used in isocratic HPLC systems.
In most systems much of the mobile phase can be recycled and reused. This saves money by reducing solvent consumption and the need for solvent disposal.
Key benefits:
- Unique peak detection algorithm accurately defines peaks and diverts them to waste
- Installs easily into any isocratic LC system
- Saves up to 90% of solvent consumption
- Reduces solvent disposal costs
- Pays for itself in 60 to 90 days
- Easy to use — no complex programming
- Returns reliably clean solvent to mobile phase reservoir
- Automatic performance validation
- NIST traceable calibration certificate included as standard
SolventTrak excels over traditional solvent recycling systems:
Traditional recycling systems use a fixed voltage level (or threshold above baseline) that must be exceeded before peaks can be detected. If the baseline changes, new settings must be applied or contaminants may be recycled instead of being sent to waste. Conversely, pure solvent may be sent to waste instead of being recycled.
SolventTrak incorporates a unique integration algorithm to accurately detect peaks in the eluent. This ensures all contaminants are eliminated, even if chromatography system conditions cause the baseline to drift up or down.
SolventTrak is Reliably Accurate:
SolventTrak-II automatically detects eluting peaks and diverts them to waste while sending clean, uncontaminated solvent back to the reservoir for recycling.
How SolventTrak works:
The signal from any HPLC detector is connected to the SolventTrak. The SolventTrak monitors and continuously displays the voltage level on a large, easy-to-read LCD. SolventTrak automatically detects eluting peaks and sends them to waste using an inert solvent diverter valve. All clean, uncontaminated solvent is sent back to the reservoir for reuse.
When a peak is detected, it is indicated on the LCD display and by an audible alarm (that can be disabled). The peak detection sensitivity can be adjusted by changing the peak width and peak threshold parameters. This is easy to do using the buttons on the front of the SolventTrak.
Additional features for enhanced purity:
If required, an additional time delay can be set after a peak has been detected. This allows the volume of solvent between the detector and the valve to be sent to waste, enhancing the accuracy and purity of the recycling.
The solvent divert valve can also be manually switched using TTL, contact closure or via the front control panel.
Easy setup, testing and validation:
The SolventTrak easily installs into any isocratic HPLC system. It 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 useful for both setup, testing and validation.
NOTE: Each SolventTrak II is calibrated and certified to an NIST traceable standard and includes a Certificate of Validation. SolventTrak II complies with CE requirements. Power requirements are 95-250V AC self switching.
