AGILENT LIGHT TRAP ASSEMBLY PL0890-0580

The AGILENT LIGHT TRAP ASSEMBLY PL0890-0580 is an optical component used in Agilent evaporative light scattering detectors (ELSD). Mounted opposite the illumination source inside the ELSD optical chamber, the light trap captures the transmitted incident beam and prevents internal reflections within the instrument body. Its primary use is to maintain a low, stable baseline and accurate scattered-light detection for non‑UV active analytes during HPLC or preparative chromatography.

Key Features:

• Function: captures transmitted incident beam and eliminates internal reflections in the ELSD optical chamber.
• Application: intended for use in Agilent Evaporative Light Scattering Detectors (ELSD) integrated with Agilent LC systems.
• Role: optical assembly / service part for the ELSD detection cell to preserve correct scattered-light measurement.

Advantages:

• Reduces internal reflections and stray light, producing a more stable baseline and lower background noise in ELSD signals.
• Supports accurate, repeatable detection of non‑volatile analytes by preserving the integrity of the scattered‑light measurement.
• Facilitates maintenance of ELSD optical performance by providing a dedicated, replaceable assembly for the detector optical path.
