Going beyond HPLC The Problem—Detection No HPLC or UHPLC detector is perfect. UV detection is the most widely used technique, but it fails to detect compounds without chromophores. Other universal detectors do not combine application versatility with reliability. This results in detection gaps. The Solution The Thermo Scientific Dionex Corona ultra RS Charged Aerosol Detector is the solution. Charged aerosol detection delivers performance that refractive index (RI), low-wavelength UV, and evaporative light scattering (ELS) detectors simply cannot match. It measures analytes that other...

Charged Aerosol Detection What makes any detector useful is its ability to accurately measure a wide range of analytes with consistent response. However, most detectors exhibit limitations. Often, one analyte responds more strongly than another, or may not respond at all. The Corona ultra RS detector measures charge that is imparted to analyte particles, with the charge being in direct proportion to the amount of the analyte in the sample. Measuring this charge is accurate and consistent, regardless of the analyte. The result is that the detector can quantify any nonvolatile analyte—this...

Consistent response and a wide dynamic range Consistent Response Detector Response for Nonvolatiles 10.7% RSD variation in CAD response among 1.0 µg samples by flow injection 250,000 200,000 150,000 100,000 50,000 Forced Degradation The Corona ultra RS detector is unique among universal detectors in that it allows quantitation across a range that exceeds four orders of magnitude. This wide dynamic range provides significant advantages for the simultaneous measurement of an analyte and low-level impurities in a single run. In the forced degradation example shown below, trace levels of...

Enhanced performance Enhanced Sensitivity The Corona ultra RS detector provides an enhancement in sensitivity when used with UHPLC. Sub-nanogram levels of detection can be readily achieved, but there is more than just greater sensitivity. More importantly, the level of sensitivity is consistent across analyte types. Achieving New Levels of Sensitivity 500 pg of each sugar on column Glucose Sucrose Lactose Complementary to UV and MS Detection The Corona ultra RS is an ideal primary detector. However, when combined with UV, diode array detection (DAD), or MS, it provides an orthogonal and...

Application solutions Algal Oil Lipid Profile Fatty Acids HPLC is a powerful tool for lipid analysis. With UV detection, quantitation is made difficult Py differing relative response due to the wide variety of structures. Other universal detectors demonstrate a lack of response consistency making relative quantification difficult. With response independent of chemical structure, charged aerosol detection delivers consistent, predictable results with no optimization. Total Glycerides of Biodiesel The same detector can be used to assess purity or to perform in-process quality control of...

Biopharmaceutical Analysis Pegylated Protein Analysis of biopharmaceuticals present new challenges. Complex mixtures of large and small molecules, many without chromophores, can be analyzed using charged aerosol detection. PEGylated MAb PEGylation helps the biological stability of therapeutic monoclonal antibodies (MAbs) but measuring the residual PEG can be difficult. With predictable response irrespective of the analyte, charged aerosol detection can be used to measure residual PEG in PEGylated proteins. With its sensitivity and dynamic range, both low levels of the PEG impurity and the...
