Solvent selection valve module

• Allows use of alternate B solvent with changeover programmed into the method or selected during the run.
• Purify with one solvent followed by column wash with an alternate solvent.
• Dedicated port to automatically load samples. PeakTrak can automatically run sequential injections of the same sample without user input.

Fractionation valve for targeted collection

Use PeakTrak software to control optional six-port fractionation valve to collect peaks based on detection or within time windows.

Peak cutting options

Trigger peak collection via slope, threshold, or time windows. Detect at one, two, or all wavelengths using the internal UV or UV-vis PDA detector. Alternatively add an ELSD or other external detector.

Evaporative Light Scattering Detector (ELSD)

ELSD has self-contained flow splitter pump for minimal sample loss.

Sample load cartridge

Load low-solubility samples with confidence. Use as a guard column with reusable columns.

Error-free RFID detection

CombiFlash Torrent recognizes RediSep columns and automatically selects an optimized purification method. Foxy R2 RFID sensors allow for mixed racks and unlimited fractions with intelligent rack management

Automated six-port injection valve

Enables true walk-away automation of column equilibration, sample loading, purification, column and cartridge air purge, and post-run valve cleaning.

Patented active level sensing

Active level sensing ensures adequate solvent for purifications and prevents waste overflows.
