1-10 ACQUITY UPLC I-Class System
columns, specially designed ACQUITY UPLC columns maximize its
high-pressure capabilities. Compared with traditional HPLC columns,
ACQUITY UPLC columns deliver superior resolution and sensitivity in the
same run time or equivalent resolution and greater sensitivity with faster run
times.
eCord technology
ACQUITY UPLC columns include an eCord™ column chip that tracks the
usage history of the column. The eCord column chip interacts with the system
software, recording information for as many as 50 sample queues run on the
column. The eCord column chip provides documentation of the column used
for each chromatographic run and records the following information:
• Number of injections onto the column
• Number of samples injected onto the column
• The highest pressure that the column has experienced (and the date)
• The highest temperature the column has experienced (and the date)
In addition to the variable column usage data, the eCord column chip also
stores these fixed, column-manufacturing data:
• Unique column identification.
• Certificate of Analysis.
• QC test data.
When you attach the eCord column chip to a receptacle on the column heater
or column manager, information is automatically recorded by the system. No
user action is required.
Detectors
These specially matched detectors operate with lower flow cell volume,
minimized tubing volume, and specialized fittings to control bandspreading
and maintain the characteristic narrowness of the peaks. The small-particle
chemistries utilized in UPLC system chromatography produce very narrow
peaks. The ACQUITY
®
TUV, PDA, and e λ PDA detectors and mass
spectrometers collect data at sufficiently fast rates, to acquire these peaks
without affecting the sensitivity or accuracy of the peak measurement.
