Ultra Performance in Fluorescence Detection:

Low volume flow cell design (<2μL) – The axially illuminated design of this flow cell enables greater light absorption, thereby enhancing sensitivity, despite it’s reduced cell volume.

High-intensity light source, low-noise electronics and low dispersion optics – maximizes light throughput ensuring optimal signal-to-noise performance as compared to conventional fluorescence detectors for LC

Support for data rates up to 80HZ – fit the requirements of any ultra fast, ultra performance application allowing for the full characterization of the narrow, sharp peaks typical of UPLC type separations

3D scanning capability – allows for the fast determination of wavelength maxima enabling efficient methods development

Facilitating Chiral Method Development Using UPSFC/MS

Chirality plays a critical role in drug profiles because enantiomers can have vastly different biological/pharmacological/toxicological properties. Chiral analysis is typically addressed in the early stage of drug discovery. Due to its superior resolving power and high speed, SFC has gained a strong foothold in the chiral analysis arena. Furthermore, SFC eliminates the use of toxic solvents typically associated with normal phase LC chiral analysis, such as hexane and chloroform.

The use of MS detection was demonstrated to facilitate chiral UPSFC method development. Taking advantage of the specificity of MS detection, a mixture of two enantiomers with different molecular masses was screened simultaneously. By examining the XICs combined with a prior knowledge of the compound mass, the compound identity was easily determined. The throughput for chiral method development was, therefore, improved two-fold, compared to a traditional SFC-UV approach. The ACQUITY UPSFC/MS System is ideal for laboratories pursuing high throughput enantioselective analyses, enantiomeric excess determination in a complex mixture or matrix, and impurity profiling.
