The purpose of this document is to describe the key differences between the SS420x and the 35900E, analog to digital converters for chromatography detectors used with EZChrom Elite Chromatography Data System. EZChrom Elite communicates with the 35900E over a LAN connection and does not control the BCD connector used to control an autosampler. The channels in the 35900E can be configured independently within one generic instrument as described below.
This guide outlines the key differences between the Agilent SS420x and the newer 35900E Analog/Digital Converters used in chromatography detectors. It explains how these devices communicate with the EZChrom Elite Chromatography Data System, noting that the 35900E uses a LAN connection rather than controlling the BCD connector for autosampler control.
The document details configuration options for single and dual-channel operations within the 35900E interface. It also provides a technical comparison of specifications between the SS420x and 35900E models, covering dimensions, signal channels, memory capacity, electrical performance, and data acquisition rates.
