English

SEDEX 81LT

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.

English

SEDEX 86LT

The SEDEX 86LT is the next‑generation replacement for the SEDEX 85LT, delivering significantly enhanced sensitivity, dramatically reduced baseline noise, and improved analytical performance across HPLC, UHPLC and SFC workflows.

English

SEDEX 100LT

The SEDEX 100LT represents the highest tier of Low‑Temperature Evaporative Light‑Scattering Detection (LT‑ELSD), delivering unmatched sensitivity, robustness, and truly universal detection for HPLC, UHPLC and SFC applications.

English

SEDEX FP

The SEDEX FP delivers robustness, sensitivity and operational simplicity for purification workflows.
Powered by SEDERE’s proven Low‑Temperature Evaporative Light‑Scattering Detection (LT‑ELSD)technology, it provides strong, stable and universal mass‑based detection for compounds that UV, RI or MS often fail to monitor effectively during preparative or high‑load chromatographic steps.

English

SEDEX PA

The SEDEX PA is SEDERE’s advanced LT‑ELSD detector dedicated to polymer, oligomer and macromolecule analysis. Specifically engineered for SEC/GPC workflows, it combines SEDERE’s signature Low‑Temperature sensitivity with the ability to operate at high temperatures when required, providing exceptional flexibility for challenging polymer matrices and high‑boiling‑point mobile phases.

Our Values

At SEDERE, performance is never accidental. It is the result of deliberate design choices, deep technical expertise, and a long-term commitment to analytical excellence. Our values define how we design our instruments and how we support our customers—today and for the future.

Sensitivity

Mastering what others cannot detect.Sensitivity lies at the core of SEDERE technology. Our detectors are designed to reveal the finest analytical details with accuracy and consistency, enabling reliable detection even where signals are faint and challenges are high.

Flexibility

Designed to serve your application, not the opposite. Analytical methods evolve, and so do laboratory requirements. SEDERE instruments are conceived to adapt seamlessly to a wide range of applications, operating conditions, and workflows offering long-term versatility without compromise.

Experience

ELSD expertise refined over decades.Dedicated exclusively to ELSD, SEDERE builds on years of scientific insight, engineering know-how, and application experience. This expertise ensures proven solutions, trusted support, and confidence at every stage of your analytical work.

Applications

Explore Our ELSD Application Database

SEDERE has developed an extensive library of ELSD application notes, illustrating the wide-ranging use of SEDEX low‑temperature Evaporative Light‑Scattering Detectors (ELSD) in LC and SFC applications. While this collection is not exhaustive, it provides concrete examples of how ELSD technology is effectively applied to solve a broad variety of analytical challenges across multiple industries.
