In many argon or helium gas supply systems, the detection of trace nitrogen (N2) is essential in determining system integrity. The Model 2120XL is the new standard in this critical measurement. It provides continuous and accurate nitrogen analysis using field-proven emission spectroscopic technology in a space-saving 19” rack-mount 3U package.
The 2120XL’s unique design raises the bar for reliability available on the market. It uses a menu-adjustable, digitally controlled sample flow for all applications. During operations, the 2120XL allows for a wide range of pressures without affecting readings with a low overall sample flow requirement. Its plasma emission detector design is based on a unique Duty Cycle Controlled System which dramatically reduces contamination and coating inside the plasma cell, offering a more efficient, reliable and accurate analyzer than any other system available.
Non-Consuming Sensing Technology
The 2120’s non-consuming sensing technology requires no regular maintenance or replacement intervals, providing ultra-low detectability without the maintenance overhead of similar high-performance systems. Even when maintenance is required, the 2120XL offers ease of access to all internal components which minimizes down time. A new design and specialized components also minimizes necessary volume for purge-down time.
The 2120XL operates with microprocessor-based electronics utilizing menu-driven functionality. Users are provided a large, luminescent LCD display and 2 x 20 vacuum fluorescent displays to show all menu functions and parameters. A preamplifier with multiple stage gains support a wide dynamic operating range. The 2120XL also offers a full diagnostics suite including a display of raw millivolt signal for troubleshooting.
