Agilent Technologies Inc. - 1100 Series Refractive Index Detector

For unrivaled sensitivity, reproducibility

The Agilent 1100 Series refractive index detector is the ideal detector for fast and reliable HPLC results when analyzing non-UV absorbing substances, such as carbohydrates,lipids and polymers. This is also the detector of choice for gel permeation chromatography.

Features

Excellent sensitivity for low limits of detection

• Minimum baseline noise enables higher signal to noise. At trace level lower limits of detection can be achieved, for example in carbohydrate analysis amounts as low as 10 nanogram sucrose can be detected.

Unmatched thermal and electronic stability for consistent reproducible results

• Electronic temperature regulation maintains a steady optical unit temperature up to 55 °C.
• Countercurrent heat exchangers keep the optical unit–and the flow cells– at a constant temperature.
• EPAC technology perfectly insulates the optics from heat-generating internal electronics as well as from environmental interference.
• The optimum light level is adjusted automatically to compensate for lamp degradation and flow cell staining. The measuring photodiodes maintain excellent, unwavering performance.
• The proven Agilent 1100 Series electronic design enables a reproducible digital signal path without external A/D converters.

Advanced features improve laboratory productivity

• The thermal design allows initial setup in less than two hours, typically. Warmup of the module is generally less than one hour for fast startup.
• To avoid warm-up time at all the detector is kept at operation conditions and the recycle valve helps to save solvent costs.
• The system can purge the reference cell automatically. Early maintenance feedback (EMF) is available with user-settable limits on time between purging.
• Autozero can be programmed as part of a method, which balances the photodiodes electrically, and ensures unattended operation of the detector.

Complete solutions

• The Agilent 1100 Series GPC-SEC system is a complete solution, based on the refractive index detector. The configuration comes with a startup kit containing an applicaiton-specific column, reference standards, as well as setup instructions and performance data.
