The analyte detection challenge
No single liquid chromatography (LC) detector delivers ideal results.
Often, one analyte responds more strongly than another, or may
not respond at all. What is most desired is the ability to accurately
measure a wide range of analytes with consistent response.
Charged aerosol detection (CAD) is a revolutionary technology that
will change the way you view every sample. This technique provides
consistent analyte response independent of chemical structure and
gives greater sensitivity over a wider dynamic range.

The area percent response is accurate and consistent across
a wide spectrum of molecules from ions to proteins.
With the flexibility and performance for analytical R&D, and
the simplicity and reproducibility needed for manufacturing
QC/QA, charged aerosol detection can be used for the analysis
of pharmaceuticals (large and small molecule), biomolecules,
foods and beverages, specialty chemicals, and polymers.
A charged aerosol detector opens new opportunities for discovery and routine analysis – the ideal detector for every lab.

Charged aerosol detection measures signals that are in direct
proportion to the amount of analytes present in a sample. These
signals are derived from the measurement of an electrical charge
originating from ionized nitrogen that is diffusionally transferred
to the surface of the analyte particle. This technology quantifies
the analyte particles that attract this charge, including those
that cannot ionize or do not have chromophores. The result is
accurate and consistent response, regardless of analyte structure.
With charged aerosol detection, you can measure any nonvolatile
and most semivolatile analytes.
Understanding charged aerosol detection
Three Simple Steps
Charged aerosol detection begins by nebulizing the eluent into droplets, which are subsequently dried into particles. The particle size increases with the amount of analyte.
A stream of charged gas collides with the analyte particles. The charge is then transferred to the particles – the larger the particles, the greater the charge.
The particles are transferred to a collector where the charge is measured by a highly sensitive electrometer. This generates a signal in direct proportion to the quantity of analyte present.

The Thermo Scientific™ Dionex™ Corona™ Veo™ detector improves
the capabilities and extends the advantages of charged aerosol
detection. The Corona Veo detector combines all the benefits of
CAD for the high speed and increased resolution of UHPLC, along
with improved low flow performance for micro LC. This detector
widens the envelope of LC conditions for mobile phase composition
to take advantage of ever advancing column technologies.
• Simple, intuitive operation
• Enhanced linear dynamic range
• Sub-nanogram sensitivity
• Expanded flow rate range optimized from 0.01 to 2.0 mL/min
The Corona Veo detector incorporates an advanced concentric
nebulizer design that facilitates the use of an expanded range of
flows and eluents:
• Easy-to-access design for maximized uptime
• Micro LC flow optimized
• Designed for simple capillary connections

The Corona Veo detector is designed to integrate into any liquid
chromatographic system, HPLC or UHPLC, from any manufacturer.
The stackable design and rugged construction allow positioning
anywhere within a system. Software drivers are available for the
Thermo Scientific™ Dionex™ Chromeleon™ Chromatography Data
System (CDS), as well as ChemStation®, EZChrom®, OpenLab®, and
Empower® 2 and 3 software.
The UltiMate SolutionCombine the Corona Veo detector with the Thermo Scientific™
Dionex™ UltiMate™ 3000 LC system to provide an ideal solution for
approximation of relative analyte concentrations, even when standards
are not available. Widen the scope of your detection possibilities using
orthogonal and complementary solutions by pairing with UV or mass
spectrometry (MS). This approach maximizes the amount of compound
data obtained from a single analytical run.
Easy integration with any LC System
New bioinert 1/32” capillary Thermo Scientific™ Dionex™ Viper™ Fingertight Fitting System provides virtually zero-dead-volume connections for any column, at any flow rate up to 1250 bar.

Flexibility for many analytesCharged aerosol detection is an ideal primary LC detection
technology that delivers predictable results without intricate
optimization. There are a minimum of parameters to optimize
enabling you to quickly begin generating data. This detector
can be used in a range of applications from basic research to
quality control.
Lipids
Lipids, including fats and oils, contain molecules with a wide
variety of structural properties and are found throughout many
products and industries. These are traditionally difficult to
characterize with conventional detection technologies. Charged
aerosol detection is a powerful tool for lipid analysis due to its
structure-independent response.
Pharmaceutical Product Characterization
Using HPLC-HILIC methodologies, counterions along with their
parent compound can be analyzed simultaneously with the
Corona Veo detector. This approach helps speed selection of
final product formulations.
Industrial Water Treatment
Polyacrylic acid, a biodegradable water soluble polymer and
environmentally toxic agent, is used as an anti-scaling inhibitor in
circulating water systems. The low levels present are difficult to
characterize using standard methods. This example shows detection by
CAD at low ppb levels.

Sugar analysis using HPLC-RI or HPAE-PAD is limited to isocratic
methods or requires complicated methodologies using dedicated
instrumentation. The Corona Veo detector offers the flexibility to use
reversed-phase gradients and HILIC modes of separation on any LC
system with dilute-and-shoot simplicity.
Power Function - Enhanced Linearization
The Power Function provides several benefits when using
charged aerosol detection. The use of this built-in feature
can provide quantitative results from unresolved peaks in a
chromatographic analysis, and simplify calibration curves for
improved mass balance determinations.
