High Performance Liquid Chromatograph (Alliance e2695 / Waters)

The High Performance Liquid Chromatograph is used in analytical chemistry to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out of the column. The Waters Alliance e2695 HPLC System is fully automated/integrated with Auto sampler & 2 detectors and is configured for the SAR(A) analysis of Crude Oil. Waters Alliance HPLC system features: Solvent management with: - quaternary solvent blending - Solvent conditioning with integral PerformancePLUS four-channel in-line degasser - low dispersion for work with microbore, narrow bore or analytical columns - programmable flow rate ramp - 11 linear/non-linear gradient curve profile -"autoblend" on-line pH-gradient generation - SystemPREP one touch wet prime Sample management with: - 120 vial capacity with 5 independent carousels - auto addition - all electric design, no compressed gases required - Waters 2695 Sample Heater/Cooler - Integral, pre-installed assembly - 4 °C to 40 °C - Waters 2695 Plunger Seal Wash - Integral, pre-installed assembly - Programmable flow rate - Waters 2695 Column Heating/Cooling - Forced air recirculation Peltier-based column heater/cooler module - Ambient minus 15° C or 4° C (whichever is greatest) up to 65° C - Integral mounting clips for column(s) and tubing's Detectors: - Waters 2489 UV/Visible (UV/Vis) Detector - Waters 2414 Differential Refractive Index Detector Fraction Collector: - Waters Fraction Collector III Software: - Computer with Empower 3 - Personal Single System Software.
