SEDEX 81LT LT‑ELSD Detector
SEDEX 81LT: High‑Value LT‑ELSD Performance for Everyday Chromatography
The SEDEX 81LT delivers reliable, cost‑effective Low‑Temperature Evaporative Light‑Scattering Detection (LT‑ELSD) for standard analytical workflows. Powered by true SEDEX low‑temperature technology, it provides high sensitivity, excellent stability, and accurate mass‑based response, making it a powerful universal detector for routine and advanced Liquid Chromatography.
Compact, robust, and engineered for simplicity, the SEDEX 81LT introduces a modern design that integrates smart optical and electronic enhancements — offering premium LT‑ELSD performance at an accessible price point.
With a footprint of just 10 inches, it fits effortlessly into any LC setup without compromising space or budget.
Designed with GLP‑friendly operation in mind, the SEDEX 81LT includes complete SOPs for streamlined method validation and regulatory compliance.
Intuitive Operation, Smart Control, and Cost‑Saving Features
The SEDEX 81LT has been engineered to make LT‑ELSD both efficient and easy to use.
It can be fully controlled:
- Directly on the instrument for quick standalone operation
- Via PC for integrated LC workflows
- Via remote shutdown, automatically powering down gas, heater, photodiode, and light source at the end of a run
→ This reduces operating costs and extends component lifetime.
With its optimized nebulizer design and low‑temperature evaporation technology, the SEDEX 81LT ensures consistent, universal detection of virtually any analyte — even those lacking chromophores, ionization efficiency or specific optical properties.
Key Benefits of the SEDEX 81LT
✔ True Low‑Temperature Evaporation for Superior Sensitivity
Protects thermally labile and semi‑volatile analytes while ensuring stable, noise‑free baselines.
✔ Universal Detection — No Chromophores, No Ionization Required
Ideal for analytes invisible to UV, RI, or MS under challenging conditions.
✔ Dedicated 81LT Nebulizer & Optimized Optical Cell
Minimizes band broadening and enhances peak shape for high‑quality chromatographic results.
✔ Broad Flow Range (200 µL/min to 2 mL/min)
Accommodates a wide variety of analytical LC conditions with fast, tool‑free nebulizer handling.
✔ SAGA — SEDEX Automated Gain Adjustment
Automatically protects against overloads and off‑scale peaks while optimizing sensitivity in real time.
✔ Full Remote Control & Intelligent Shutdown
All critical components (gas, heater, light source, photodiode) shut off automatically after analysis to preserve instrument longevity.
✔ Compact, Reliable, and Budget‑Friendly
High‑performance aerosol‑based detection in a small footprint — perfect for routine labs and cost‑sensitive environments.
Ideal Applications
- Routine HPLC analyses requiring universal detection
- Semi‑volatile and thermolabile compound analysis
- QC laboratories seeking robust low‑temperature ELSD performance
- Academic and industrial labs needing a compact, affordable universal detector
- Methods where UV or RI detection fails (no chromophore, poor refractive index contrast)
