Agilent G1315-87321: Capillary assembly with heat exchanger for high-precision chromatographic detection
The G1315-87321 is an essential component in the configuration of chromatographic detection systems, particularly those equipped with diode array detectors (DAD) or multiple wavelength detectors (MWD) from the Agilent 1200/1260 Infinity range. This capillary assembly is specially designed to integrate seamlessly into the flow cell system, with a fixed mounting directly on the heat exchanger plate, ensuring maximum heat transfer efficiency and optimal analytical reproducibility.
The main role of this capillary is to ensure accurate and stable liquid flow while regulating its temperature prior to spectrophotometric analysis. The internal diameter of 0.17 mm makes it ideal for applications requiring low dispersion and high chromatographic resolution. Made of high-quality stainless steel, it offers excellent resistance to corrosion, pressure and temperature variations, while ensuring a long service life.
The integration of a heat exchanger directly into the capillary is a decisive advantage for laboratories wishing to strictly control analytical conditions. By stabilising the temperature of the fluid entering the flow cell, the G1315-87321 reduces background variations and improves baseline stability, which are crucial aspects for high-performance analyses.
The assembly is designed with two types of precision fittings: a left-hand S-type (Swagelok, 1.6 mm ID) short screw version and a right-hand M4-type (0.8 mm ID) pre-crimped version. This design choice ensures perfect compatibility with Agilent system connectors, while providing a secure, leak-free connection. This component complies with the UNSPSC 41115701 standard for chromatography accessories.
Compatible with liquid chromatography (LC) techniques, this capillary is designed for the most demanding analytical applications, particularly in the pharmaceutical, biotechnology and environmental fields. Its "special" subtype status indicates that it is tailor-made to meet specific detector architecture requirements, enhancing its added value in customised chromatography systems.
The G1315-87321 is a high-precision component that is essential for ensuring the highest level of analytical performance in Agilent spectrophotometric detection systems. It contributes to the reliability of results, the reduction of analytical errors and the optimisation of analysis times.
