Positioning

When is the Varian 920-LC appropriate?

  • When a fully automated analytical HPLC that is capable of Fast LC applications using sub-3 Ám particle columns such as in high throughput fee-for-service laboratories
  • If an automated, premium performance analytical HPLC is required
  • For the ultimate in analytical flexibility choose from a system with low pressure quaternary gradient solvent delivery system with degasser built-in, choice of cooled or uncooled autosampler, UV-Vis or PDA detector, and option of RI, Fluorescence or ELS detector
  • When the flexibility of a low pressure quaternary gradient system with autosampler and a choice of detectors such as in method development, medium to high throughput QA/QC labs or when the highest levels of performance are required
  • Where routine automated applications of <500 samples per day must be analysed by an instrument
  • When a combined analytical HPLC and low temperature (< 65C) GPC system is required select the Varian 920-LC system with an RI detector and the Galaxie GPC 'add-in'
  • When a robust Fast LC solution is required that is also capable of conventional analytical HPLC
  • For regulated pharmaceutical laboratories just add the AIQ validation option
  • For automated method development and optimization, add Fusion AE and the CVM 500 with 6 position column selector and solvent selection valve to a Varian 920-LC

When are modular systems appropriate

  • For simple manual configurations choose from the wide range of Varian's HPLC modules such as in university teaching laboratories
  • Dedicated routine isocratic analyses such as sugars, or aromatic hydrocarbons in distillate
  • Bio-inert applications which require fully inert PEEK or titanium flow path
  • LC-MS which requires a inert binary gradient pumping system with PEEK heads and pulse damper, PEEK plumbing and an inert PEEK based injector

The major advantage of Varian compared to most other HPLC vendors is our full solution from sample preparation to service, and all components are at the highest level of competitive performance.  

  • For environmental and industrial customers, no other vendor offers the breadth of top-end GC, MS and atomic/molecular spectroscopy instrumentation and solutions.
  • For the pharmaceutical customer, no other vendor offers analytical to process scale-up in as complete a fashion as Varian, with leading edge consumables and associated NMR, dissolution and MS technologies.
