Does Waters have a direct equivalent to the Millipore Sigma Ascentis ES-Cyano, 4.6 mm x 10 cm column, in order to achieve the same exact selectivity for an existing method? - WKB123447

ENVIRONMENT

• Column equivalency
• Cyano (CN)

ANSWER

No

ADDITIONAL INFORMATION

Waters does not sell a direct equivalent to the Millipore Sigma Ascentis ES-Cyano, 4.6 mm x 10 cm column. 

Waters cannot guarantee the same selectivity on a Waters CN column for an existing method that uses an Ascentis ES-Cyano, 4.6 mm x 10 cm column.

Different CN columns will likely show different selectivity when compared under the same specific method conditions.

Waters does sell CN columns, but experimentation would need to be performed, and method changes would likely need to be performed to achieve the desired selection with a column other than the original column used.

Waters Cyano columns include:

XSelect HSS Cyano

Nova-Pak Cyano

Spherisorb Cyano

Resolve Cyano

µBondapak Cyano
