Agilent Column Compartment for HPLC

The Agilent G7129-40058 is the Integrated Column Compartment (ICC) assembly designed for the Agilent 1260 and 1290 Infinity II Vialsamplers (modules G7129A, G7129B, and G7129C). This component is a specialized housing unit that installs directly into the vialsampler module, allowing users to mount liquid chromatography columns inside the sampler itself rather than requiring a separate, external column thermostat module.

Functionally, this compartment enables the heating and temperature control of up to two HPLC columns (up to 30 cm in length) with a temperature range typically up to 80°C, provided the necessary heater elements and heat exchangers are installed. By integrating the column housing into the sampler, the system significantly reduces the length of capillary connections between the injector and the column. This reduction in "dead volume" minimizes peak dispersion, leading to sharper peaks and higher resolution, while simultaneously saving valuable laboratory bench space.

The part is often described as an "Empty Column Compartment" because it provides the structural framework and door assembly but typically requires the separate installation of specific low-dispersion heat exchangers (such as Quick Connect heat exchangers) tailored to the specific column volume and application requirements.

Used. In great condition.
