Agilent 1200 Preparative HPLC with DAD

Agilent 1200 DAD Detector Features: 

The Agilent 1200 Series DAD offers multiple wavelength and full spectral detection at up to 80 Hz sampling rate, keeping up with the analysis speed of ultra-fast LC. Even when operated at high data rates, the 1200 Series DAD SL allows precise identification, quantification and peak purity analysis at trace levels. This exceptional capability assures that your ultra-fast LC methods comply with the strictest regulatory performance requirements. 

Detector type1024-element diode array
Light sourceDeuterium and tungsten lamp
Short-term noise± 1.0 x 10 -5 AU at 254 nm and at 750 nm
Drift2 x 10 -3 AU/h at 254 nm

Wavelength range190-950 nm
Wavelength accuracy± 1 nm, self-calibration with deuterium lines, verification with holmium oxide filter
Slit widthProgrammable: 1, 2, 4, 8, 16 nm
Diode width< 1 nm
Wavelength bunchingProgrammable, 2 - 400 nm, in steps of 1 nm

Agilent 1200 Preparative Pump Features:

For isocratic and gradient separations the Agilent 1200 Series preparative pump delivers a stable and reproducible flow at both low and high flow rates. By adding a second pump, a high-pressure gradient system can be assembled easily.

  • Flow rates up to 100 mL/min at 400 bar without changing pump heads
  • Precise high-pressure binary gradient formation with low delay volume for preparative and analytical applications with flow rates as low as 0.5 mL/min
  • Extended seal lifetime by automated seal wash
  • Setting upper and lower pressure limits will turn off the pump, e.g. if the column gets blocked or leaks occur
  • Convenient system setup by automated electromagnetic purge valve
Hydraulic systemDual pistons in parallel
Settable flow range0.001 – 100 ml/min
Flow precision< 0.5 % RSD
Pressure range20 to 400 bar (5880 psi) system pressure
Compressibility compensationUser-selectable, based on mobile phase compressibility
Recommended pH range1.0 – 12.5, solvents with pH < 2.3 should not contain acids which attack stainless steel.
Control and data evaluationAgilent ChemStation for LC Communications Controller-area network (CAN), RS-232, APG Remote: ready, start, stop and shut-down signals, CAN-DC OUT, LAN optional
Safety and maintenanceExtensive diagnostics, error detection and display (through control module and Agilent ChemStation), leak detection, safe leak handling, leak output signal for shutdown of pumping system. Low voltages in major maintenance areas.
GLP featuresEarly maintenance feedback (EMF) for continuous tracking of instrument usage in terms of seal wear and volume of pumped mobile
phase with user-settable limits and feedback messages. Electronic records of maintenance and errors.
HousingAll materials recyclable.
