Agilent G1390A Universal Interface Box: Seamless integration into Agilent 1100 systems
The Agilent G1390A has been designed to meet the specific needs of laboratories equipped with the 1100 series. This module acts as a gateway between the detectors and the fraction collector. It is essential for the operation of the LC-MSD (G1946 C/D), the FLD fluorescence detector (G1321A), the RID refractometer detector (G1362A) and third-party detectors used as peak triggers. However, it is not required for the VWD (G1314A), MWD (G1365A/B) and DAD (G1315A/B) detectors, as these communicate directly via the CAN bus of the 1100 series. This selective use allows the module to be adapted only when necessary, ensuring optimal flexibility in the configuration of analytical systems.
Features and peak-based trigger control
The strength of the G1390A lies in its ability to efficiently manage trigger signals for fraction collection. Thanks to its analogue input, it allows triggering to be configured based on parameters such as peak threshold or slope. In addition, its GPIO interface expands the possibilities with digital triggering. The four integrated relays provide clear marking of collected fractions, improving traceability and reliability of results. The user also benefits from visual status indicators: a green LED indicates that analysis is in progress, yellow indicates that the instrument is not ready, while a red LED immediately alerts the user to any errors affecting the proper functioning of the instrument.
A robust, compact and easy-to-maintain tool
With its small dimensions (100 x 140 x 30 mm), the G1390A fits easily into the laboratory environment without cluttering the workspace. Its 22 to 25 V DC power supply and power consumption of less than 100 mA ensure compatibility with Agilent module standards. System maintenance is also simplified: regular firmware updates can be performed to correct certain malfunctions or improve compatibility, ensuring long-term use. If an internal problem is detected by the device, the user is immediately notified, facilitating diagnosis and rapid intervention.
