1290 Infinity Thermostatted Column Compartment (G1316C)
The Agilent 1290 Infinity Thermostatted Column Compartment (TCC)
controls the temperature between 10 °C below ambient and up to 100 °C
at 2.5 ml/min and 80 °C at up to 5 ml/min, respectively. The temperature
stability specification is ±0.05 °C and the accuracy specification ±0.5 °C
(with calibration)
contact with the thermostat vanes, still- air temperature in the column
environment and most importantly by pre- heating (or cooling) the mobile
phase by passing it through a heat exchanger before entering the column.
There are two independent temperature zones in each TCC which can
work together for long columns up to 300 mm length or work at different
temperatures for short columns of 100 mm length or less.
The module comes with a 1.6 µl low dispersion heat exchanger and each
valve kit contains additional low dispersion heat exchangers for each
column. The low dispersion heat exchangers, up to 4, can be mounted
flexibly inside the TCC. For conventional HPLC operation, 3 µl and 6 µl
built- in heat exchangers are also available.
Each TCC can accommodate one internal valve drive to facilitate valve
switching applications from simple switching between two columns to
alternating column regeneration, sample preparation or column
back- flushing. Each valve head comes as a complete kit containing all
required capillaries, additional low dispersion heat exchangers and other
parts.
The switching valves have exceptional ease- of- use and flexibility when
making connections to the valve: When pressed, the drive unit of the
Quick Change Valve slides forward for easy access (see
page 18 left). Alternative valve heads can be interchanged by the user on
the drive mechanism for different applications (see
right). Note the RFID tag on top of the valve head.
