Metoric Core, Core-Shell Columns, for basic compounds, coordination compounds - YMC

Excellent peak shape on basic compounds

Meteoric Core C18 column is a high resolution column which provides excellent peak shapes for basic compounds (Peak 1 and 2) compared to sub-2 µm Core-Shell columns. Chromatographers can expect ultrafast analysis of basic compounds with highly quantitative and sensitive analysis by using Meteoric Core C18.

Excellent peak shape on coordination compounds

Meteoric Core C18 is able to provide excellent peak shapes for coordination compounds which are often adsorbed to a column, resulting from a strong interaction with impurities such as trace amount of metal ion. Meteoric Core is suitable for a quantitative analysis of coordination compounds.

High column efficiency

Meteoric Core C18 has high column efficiency which is almost equivalent to sub-2 µm columns over a wide range of flow rate.

Low pressure and high throughput

The operating pressure of Meteoric Core is one half to one fifths of sub-2 µm Core-Shell type columns. High throughput analysis using Meteoric Core could be expected even with longer length columns since the usable maximum flow rate of it is higher than competitors’ sub-2 µm Core-Shell.

Ultra fast analysis and excellent resolution

Meteoric Core C18 can shorten the analysis time by two thirds compared to the conventional fully porous C18 column with the same column dimension and under the same analysis condition. Moreover, it maintains the theoretical plate number at a two times faster flow rate. It allows us to decrease analysis time by one thirds while maintaining resolution, and at an operating pressure less than 5,000 psi.
