Automatically performs a variety of method scouting processes
The high-speed performance of SFC can shorten the time required for method scouting.
It automatically generates a large number of methods by utilizing combinations of up to 12 columns, four modifiers, and different ratios of modifiers to mobile phase.
Chiral analysis with "Nexera UC Chiral Screening System"
CHIRALPAK® Series and CHIRALCEL® Series columns (Daicel Corporation) for chiral analysis are capable of resolving a wide variety of compounds by showing complementary separation targets.
The combination of the Nexera UC Chiral Screening System and these columns simplifies method scouting for chiral analysis.

The Nexera UC LC/SFC switching system makes it easy to switch between LC and SFC just by adding a single LC pump to an SFC system. By utilizing this system, conventional LC analysis can be performed as usual. At the same time, with samples that are difficult to separate using LC, conditions can be investigated with SFC which has different separation modes than LC.

Using the System for Chiral Analysis
Various methods are needed to separate chiral compounds, structural isomers, and other such substances in all sorts of fields, such as pharmaceuticals, foods, and environmental testing. Because supercritical fluid chromatography (SFC), which uses supercritical CO2 as a mobile phase, exhibits different separation behavior than ultra high performance liquid chromatography (UHPLC), superior separation results can be quickly obtained during method development by screening with both SFC and UHPLC separation methods.
By simply adding one solvent delivery unit to a standard SFC system, both SFC analysis and UHPLC analysis can be performed using a single system. Sharing the solvent delivery unit (for pumping organic solvents), autosampler, column oven, and detector for both SFC and UHPLC analysis minimizes space requirements and equipment cost and improves the equipment utilization rate. Moreover, this allows for selection of the optimal column from among a combined total of up to 12 SFC and UHPLC columns, when performing method scouting.

Purging of mobile phases, which is required when switching between SFC and UHPLC, is accomplished by simply executing a batch table automatically generated by the dedicated software. That means even first-time users can smoothly switch between SFC and UHPLC analysis. It also enables multiple mobile phases and columns to be used for method scouting. No reconnecting of flow lines is required when switching from SFC to UHPLC (or from UHPLC to SFC). Consequently, the system can switch continuously between both analysis modes without being affected by the preceding mode.
SFC and UHPLC involves significantly different mobile phases and separation characteristics, but analysis can be performed reliably without effects from switching modes by simply purging the flow lines.
In this example, methods were scouted for two types of chiral standard samples using both SFC and UHPLC. UHPLC and SFC parameter settings in the method scouting software can be specified by clicking a button to switch between modes.
A comparison of UHPLC/SFC chromatograms using three different columns indicated that UHPLC parameters provided better separation for omeprazole and SFC parameters provided better separation for imdapamide. LabSolutions software makes it easy to compare chromatograms from multiple sets of data.
The LCMS-2050 provides both high speed and high sensitivity analysis even in a small design. We have achieved the utmost in both miniaturization and high performance with Shimadzu's technology cultivated over many years of MS development. A single platform, a single solution for LC detection, the LCMS-2050 has the power to deliver better results with incredible simplicity and unparalleled robustness.
