ODS-AM is produced in large lots using ultra pure YMC silica as a base material and a multi stage synthesis process. For the derivatisation, monomeric bonding chemistry is applied followed by an extensive endcapping process to reduce the silanol activity.
The resulting ODS-AM packing is extensively tested to ensure compliance with specifications set for very low variations in physico-chemical properties.
The recommended pH range of using YMC-Pack ODS-AM columns is 2-7,5. Flush acid and buffer salts before storage. Store the column in methanol / water = 70/30. If columns are affected by undesired contaminants and back pressure increases, flush the column with THF. Clogged inlet frits can be cleaned by changing the flow direction or replacement.
For detailed information please refer to the "Column Care and Use Instructions”, which are shipped with each analytical column.
