Agilent 1100 Series - G1310A HPLC Isocratic Pump

Agilent 1100 Series - G1310A HPLC Isocratic Pump

Cambridge ID #: 14776

The HP / Agilent 1100 HPLC series is the current model and arguably the best design in the industry because of the optimized design of the quaternary pump ensuring virtually pulse-free and stable solvent flow, with dual floating pistons in series, precisely servo-controlled. This design with variable stroke volume allows pulse-free solvent delivery and efficient mixing. An inlet-valve electronically activated and synchronized to piston stroke - eliminates vapor formation with volatile solvents and is maintenance free. With high-speed proportioning valve and pre-configured vacuum degasser, for convenient low-pressure mixing of up to four solvents and highest flexibility in solvent choices.

 

 Features:

  • Ease-of-use - handheld control module lets you enter operating parameters fast, store methods easily and display pressure profile, diagnostics and task-oriented information.
  • Durable - stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE ensure long lifetime. Seal wash option for high salt mobile phases keeps maintenance to a minimum for lower operation costs.
  • Wide flow range - up to 10 ml/min for broad HPLC work, including semi-preparative separations.
  • Better for GLP - built-in leak and pressure test with graphical presentation of pressure profiles, and early maintenance feedback.

 

Specifications:

  • Hydraulic system: Dual piston in series pump with proprietary servo-controlled variable stroke drive, floating pistons and active inlet valve
  • Settable flow range: .001– 10 ml/min, in 0.001 ml/min increments
  • Flow range: 2 – 10.0 ml/min
  • Recommended pH range: – 12.5, solvents with pH > 2.3 should not contain acids which attack stainless steel.
  • Operating voltage: 230V

EFC is the gold standard for robust and reliable nanoflow performance and delivers the precise flow and gradient performance necessary for retention time reproducibility and stable ion generation essential for high sensitivity nanospray MS performance.

Features:

  • Electronic Flow Control (EFC) provides real-time adjustment of the flow rate throughout the analysis for reliable and reproducible results.
  • Micro vacuum degassing with very low internal volume per channel (1 mL) for fast changeover of mobile phase and quick purge.
  • Control from handheld controller for convenient local status monitoring.
  • 2nd generation flow sensors.
  • Application focus: High resolution separations and high sensitivity MS detection. Proteomics is a typical application area for the nanoflow pump.
