The Chroma is a highly versatile, ultra-accurate trace gas analyzer

One of the most flexible trace gas monitoring solutions available to the market, the Chroma is optimized to specific background gases to ensure optimum performance for your application.

A trace gas analyzer configurable to a wide range of applications

Offering a non-depleting Plasma Emission Detector (PED), Flame Ionization Detector (FID) and Thermal Conductivity Detector (TCD), the Chroma analyzer is one of the most versatile gas analyzers for trace gas measurement available. Most applications will be satisfied by a single 4U rack analyzer configuration, making the Chroma a compact, cost-effective solution for continuous process control or quality monitoring.

High versatility for diverse application needs

Applications that depend on the very highest levels of product purity depend on trace analysis of exceptional sensitivity and performance. Impurities requiring measurement are both diverse in nature and found in a number of background gas streams, so high flexibility is also a must. Measurements need to be reliable, so a technology that can provide stability is essential. No matter what your application monitoring requirements, you’ll also want a solution that is easy to use and has a low lifetime cost-of-ownership. We don’t believe you should have to compromise.

A no-compromise solutuion

The Chroma’s flexible ultra-trace analysis is delivered through a smart combination of cutting-edge sensing technology and intelligent control software. Benefiting from the fast, accurate, sensitive and selective response of Servomex’s non-depleting Plasma Emission Detector (PED) cell, Flame Ionization Detector (FID) or Thermal Conductivity (TCD) technologies, the Chroma offers sophisticated configuration and performance options which are far ahead of the competition.

Easy and intuitive to use

Added to the Chroma’s measurement performance is its ability to provide an easy-to-use solution with added flexibility. Feature-rich software permits full device interaction remotely via Ethernet/Internet, while a full range of reporting options provide simplified statistical data analysis. The Chroma also features a user-friendly high resolution TFT color LCD for easy local configuration and interaction.

A powerful solution for process control and quality monitoring

The Chroma is a mainframe analyzer fully customizable to your application, with a number of performance and cost-saving benefits.

Software optimization

The Chroma is optimized via sophisticated and flexible operational software that offers access to all device functions via a PC. This updated software ensures increased security and stability, with a robust, Windows 10-based operating system.

Easy to use for complex applications

The Chroma has a fully automated, tune-to-the-application system for simplicity of use. PlasmaHC and ArgonSep technology supports the sophisticated sensor options, while a large, clear display screen makes operation easier.

Safer, cost-effective measurements

For CH4/NMHC measurements, the Plasma HC system requires no FID and therefore no H2 fuel gas, reducing costs and enhancing safety.
