HPLC Column Selectors: The column selector is an integrated HPLC automated column selection and switching module. Both a fully automated and push-button operated column selector are available. The module can accommodate six (6) analytical HPLC columns plus one built-in By-PASS line.
* Quaternary solvent blending supports isocratic and gradient applications with 11 unique gradient profile curves. Blend up to 4 solvents in any proportion with Auto-Blend Technology. Compatible with a wide range of solvent types to support reversed-phase, normal-phase, GPC, SEC, and IEX application.
The Waters Alliance 2695 Separations Module is a high performance liquid chromatographic system with a quaternary, low-pressure mixing pump and inline vacuum degassing. Flow rates from 50 uL/min to 5 mL/min can be generated for use with 2.1 mm ID columns and larger. The autosampler has a maximum capacity of 120 vials (12x32, 2-mL) with programmable temperature control from 4 to 40°C. A heated column compartment provides temperatures from 5 degrees above ambient to 65°C.
The 2545 Binary Gradient Module (BGM) is a high-pressure mixing binary gradient pump that serves as the primary solvent delivery device for the Waters AutoPurification System, enabling subsequent isolation and purification of targeted compounds. The 2545 Binary Gradient Module: Operates at analytical and preparative scales Performs between flow rates of 0.50 to 150.00 mL/min with a pressure up to 6000 psi Integrates solvent selection valves on each solvent delivery channel to allow for rapid solvent changeovers and system purges
