Agilent Technologies - 1260 Infinity Refractive Index Detector
Manufactured by Agilent Technologies
High sensitivity and robust detection
The Agilent 1260 Infinity Refractive Index Detector (RID) is the ideal detector for fast and reliable LC results when routinely analyzing non-UV absorbing substances, such as carbohydrates, lipids and polymers. The 1260 Infinity RID is also the detector of choice for gel permeation chromatography (GPC) or size exclusion chromatography (SEC).

Features of 1260 Infinity Refractive Index Detector
- Minimum baseline noise results in excellent sensitivity for low limits of detection. More details
- Unmatched thermal and electronic stability for consistent, reproducible results. Electronic temperature regulation maintains a steady optical unit temperature of up to 55 °C. More details
- Thermal design allows initial setup in typically less than two hours. Warm-up of the module is generally less than one hour for fast startup.
- Optimum light level, adjusted automatically to compensate for lamp degradation and flow cell staining.
- Recycle valve that can be switched on to keep the system at operating conditions, avoiding warm-up time and saving solvent.
- User-settable purge and wait times enables automatic purging of the reference flow cell.
- Convenient front access for inspection and maintenance of tubing and valves.
- Early Maintenance Feedback (EMF), with user-settable limits for continuous tracking of the reference flow cell purging.
- Extensive diagnostics, error detection and display with Instant Pilot controller and Agilent Lab Advisor software.
