acetonitrile/water. Failure to perform this intermediate step could result
in precipitation of the buffer salt in the column when 95% acetonitrile
is introduced. Completely seal the column to avoid solvent evaporation
and drying out of the chromatographic bed.
V. eCORD INTELLIGENT CHIP TECHNOLOGY
a. Introduction
The eCord Intelligent Chip Technology represents a significant
advancement in column usage tracking management which can be
realized if the column is installed on an ACQUITY UPLC System.
The eCord Intelligent Chip provides a paperless tracking history of the
column’s performance and usage throughout its lifetime. The eCord
is permanently attached to the column body via a tether that cannot
be removed. This ensures that the history of the column is always
accessible to the user of that column.

At the time of manufacture, information such as the performance test
chromatogram, column manufacturing QC data and Certificates of
Analysis is downloaded onto the eCord. This information may then be
accessed via the ACQUITY UPLC console once the column is installed.
b. Installation
The eCord device can be read by connecting the yellow fob to the
reader/writer located on the right-hand side of the ACQUITY UPLC
Column heater module. Once the eCord is connected to the magnetic
catch on the column heater, column identification and overall
column usage information can be accessed.

c. Manufacturing
The eCord Chip provides the user with the Batch Certificate of Analysis
and Performance Test Chromatogram.
