System Components
The Agilent 1290 Infinity Autosampler
The Agilent 1290 Infinity Autosampler offers the well-established Agilent
flow-through design with variable volume injection and takes it to new levels
of performance. New inert materials in the metering device seal and needle
seat help to achieve extremely low carryover. The reduced hydraulic volume of
the flow path is suited to faster gradients and the ability to use overlapped
injections and automatic delay volume reduction (ADVR) contribute to faster
cycle times and even faster gradient delivery to the column. The system draws
exactly the set volume of sample solution without waste and achieves high
reproducibility across the range from sub-microlitre to maximum injection
volume of 40 µl. The standard installed injection capillary allows injections to
20 µl.
