1260 Infinity Refractive Index Detector 
Product Description
The sensitive and robust 1260 Infinity Refractive Index Detector (RID) is the detector of choice for fast and reliable LC results when you are routinely analyzing non-UV absorbing substances, such as carbohydrates, lipids and polymers. The detector is also ideal for gel permeation chromatography (GPC) and size exclusion chromatography (SEC).
  • Minimum baseline noise for excellent sensitivity and low limits of detection.
  • Consistent, reproducible results - unmatched thermal and electronic stability using electronic temperature control (ETC) maintains a steady optical unit temperature of up to 55°C.
  • Fast start-up - thermal design means initial setup is typically less than two hours; it generally takes less than one hour for the module to warm up.
  • Optimized light levels - light intensity is adjusted automatically to compensate for lamp degradation and flow cell staining.
  • Save time and solvents - you can use the recycle valve to keep the system at operating conditions, avoiding warm-up time and saving solvent.
  • Automatic purging of the reference flow call using programmable purge and wait times.
  • Easy maintenance - convenient front access for inspection and maintenance of tubing and valves.
  • Early maintenance feedback (EMF) for continuous tracking of instrument usage (purging lamp burn time) with customizable limits and feedback messages.
  • Extensive diagnostics, including error detection and display with Instant Pilot controller and Lab Advisor software.
