HPLC Detectors
Fluorescence Detector
Column/Instrument Specifications & Methodology
The Fluorescence Detector provides selective, sensitive detection for fluorescent analytes in HPLC workflows. It complements UV-Vis detectors where low-level fluorescent species require enhanced sensitivity. Laboratories choose fluorescence detectors for trace-level quantitation and enhanced signal-to-noise in targeted assays.
Throughput, Compatibility & Reagent Ecosystem
Compatible with common HPLC flow cells and detector interfaces, the unit supports method development and routine QC runs. Buyers should confirm excitation/emission wavelength needs and flow-cell compatibility when requesting quotes to ensure detector suitability.
ELSD – Evaporative Light-Scattering Detector
Column/Instrument Specifications & Methodology
The Evaporative Light-Scattering Detector (ELSD) is used for detecting analytes that lack strong UV absorbance, such as lipids, polymers, and sugars. ELSD provides mass-sensitive detection by evaporating mobile phase and scattering light from analyte particles. Laboratories use ELSD when UV or fluorescence detection is not suitable for target compounds.
Throughput, Compatibility & Reagent Ecosystem
ELSD units integrate with common HPLC flow cells and require compatible mobile-phase volatility to ensure proper nebulization and evaporation. Buyers should specify typical solvent systems and flow rates during procurement to ensure detector selection aligns with method conditions.
RI – Refractive Index Detector
Column/Instrument Specifications & Methodology
The Refractive Index (RI) Detector measures changes in refractive index and is suitable for analytes that do not absorb in the UV range, such as sugars and polymers. It complements ELSD and provides a universal detection option for certain classes of analytes. Labs select RI detectors for applications where mass-insensitive detection and non-derivatized analyte measurement are required.
Throughput, Compatibility & Reagent Ecosystem
RI detectors require stable column temperature and compatible mobile phases; buyers should confirm solvent systems and intended method conditions when requesting quotes to ensure detector selection aligns with method stability constraints.
DAD – Diode Array Detector
Detector Performance & Wavelength Range
The DAD Diode Array Detector provides broad spectral scanning across UV-Vis wavelengths for HPLC method development and routine QC. It captures full-spectrum peaks to support peak purity checks and spectral identification during gradient and isocratic runs. The detector fits analytical laboratories focused on chromatographic method qualification and stability testing. Procurement teams source it for instrument upgrades and method transfer workflows where spectral resolution and reliable retention-time correlation are required.
Signal Fidelity & Integration for QC
High signal-to-noise performance and integrated data output streamline QC reporting and compatibility with common chromatography data systems. The detector supports scan and fixed-wavelength modes for flexibility across assays. It is positioned for institutional buyers requiring repeatable spectral data for batch release and method validation.
UV-Vis Detector
Wavelength Range & Sensitivity
The UV-Vis Detector delivers stable fixed-wavelength and variable-wavelength absorbance detection for HPLC analysis. It is suited to assays that rely on single-wavelength quantitation and routine QC throughput. Sensitivity and linearity are primary selection factors for analytical QC teams evaluating trace-level assay performance. The detector aligns with laboratories requiring dependable absorbance response and simple operational modes for routine release testing.
Integration with Chromatography Systems
Designed for seamless integration with common chromatography data systems, the detector supports standard analog and digital outputs for data capture. Procurement teams often select this unit for method transfer projects and instrument fleet standardization within QC departments. It is positioned for institutional buyers seeking repeat procurements for replacement or capacity expansion.
