This pack of three guard columns is suited to laboratories that want replaceable protection for compatible NUCLEODUR C18 ec analytical methods.

Frequently Asked Questions

1. What is the Macherey-Nagel NUCLEODUR C18 ec guard column used for?

It is used ahead of a compatible analytical HPLC column to help protect the main stationary phase from strongly retained contaminants and particulate loading.

2. What are the dimensions of the Macherey-Nagel 761931.3 guard column?

Each guard column is 4 mm long with a 3 mm internal diameter.

3. What stationary phase is used in the Macherey-Nagel 761931.3 guard column?

It uses NUCLEODUR 100-3 C18 ec with a 3 µm particle size.

4. How many guard columns are supplied?

This configuration is supplied as a pack of three guard columns.

5. How does this NUCLEODUR guard column compare with an Agilent ZORBAX C18 guard cartridge?

The Macherey-Nagel guard column is the better fit when the analytical method uses NUCLEODUR 100-3 C18 ec and requires matched stationary-phase selectivity. An Agilent ZORBAX guard cartridge is more appropriate for systems built around the corresponding ZORBAX analytical phase and holder.
