🔬 SparkFlux2000

Lingfeng CAD Charged Aerosol Detector

A high-sensitivity universal mass detector for non-volatile compounds without UV absorption

What is the SparkFlux2000?

The SparkFlux2000 is a universal HPLC detector based on charged-aerosol detection. Column effluent is nebulized, the solvent is evaporated, and the remaining particles are charged and measured. Because the response is based on particle mass rather than UV absorption, it detects a very wide range of non-volatile and semi-volatile compounds — including those with no chromophore.

As the authorized regional distributor for the Lingfeng CAD, WeikeTory provides genuine products, application method support and local technical service.

Universal response — independent of chromophores; detects sugars, lipids, alkaloids, excipients and more.
High sensitivity — down to the nanogram level.
Wide dynamic range — about four orders of magnitude.
Good repeatability — peak-area RSD can be ≤1%.

Applications

Typical Applications

Pharmaceutical excipients

Quantification of PEG, Tween, Poloxamer and other non-UV-absorbing excipients.

Natural products & TCM

Alkaloids, saponins and oligosaccharides with weak or no UV absorption.

Lipids & LNP

Phospholipids (e.g. DSPE) and other lipid-nanoparticle excipients for mRNA-related research.

Food & sugars

Sugars, edible oils (triglycerides) and other components for food quality testing.

Generic consistency evaluation

Universal detection of components lacking chromophores.

Environmental

Per- and polyfluoroalkyl substances (PFAS such as PFOS/PFOA).
