CP4787 Agilent – Universal Quick-Seal/Press-Fit connector for 0.53 mm GC columns, ideal for large-volume injections
The Agilent CP4787 is a universal Quick-Seal/Press-Fit connector specifically designed to meet the rigorous requirements of gas chromatography (GC) applications. This model is perfectly suited for capillary columns with an internal diameter of 0.53 mm and is commonly used in tandem with retention gaps during large-volume injections.
Thanks to its glue-free design, the CP4787 allows for simple, quick and clean installation, eliminating the risk of contamination or leakage. The Quick-Seal system guarantees optimal sealing without specialised tools, making operation accessible even to inexperienced technicians. A simple press is all it takes to form a reliable, airtight connection.
This connector is designed to operate at up to 300°C in isothermal mode and up to 325°C in programmed mode, making it compatible with a wide range of analytical conditions, including analyses requiring high temperatures. Its robust construction also ensures excellent chemical stability, which is essential for sensitive applications such as GC/MS.
The CP4787 integrates ideally with fused silica columns, particularly those that have undergone specific deactivation treatments (methyl, PEG, cyano/phenyl). It can be used with various solvents, depending on the polarity level of the sample, thanks to its broad compatibility with different types of retention gaps.
Designed for durability, this glass or pressed quartz al connector offers consistent and repeatable performance. It is also colour-coded ( blue) for easy identification in multi-equipment laboratories.
The CP4787 is therefore the ideal accessory for improving analytical accuracy, reducing downtime due to leaks, and optimising the performance of high-volume GC analyses. It is designed for quality control, pharmaceutical, environmental, petrochemical, and food laboratories.
