Greenpix - Advancing Modular, High-Performance Silicon-Based Micro-GC for Real-Time Gas Analysis

Founded in 2014, APIX Analytics has been at the forefront of developing and commercializing micro gas chromatography (µ-GC) systems, with more than 1,000 units installed worldwide for applications such as natural gas and biomethane energy content analysis, as well as impurity monitoring.

Building upon this experience, the European-funded Greenpix project launched in 2022 has led to the creation of a new generation of µ-GC analyzers, named Greenpix. This next-generation platform retains the cutting-edge technologies of previous models, such as a highly sensitive micro thermal conductivity detector (µ-TCD) and the proprietary nano-gravimetric detector (NGD), while introducing novel features that enhance performance, integration, and manufacturability. These include a fully silicon-based, ultra-compact injector and a new modular design based on a fluidic manifold that enables automated assembly, reduces manual operations, and allows for flexible OEM (Original Equipment Manufacturer) integration.

Recent proof-of-concept demonstrations have underscored Greenpix’s capabilities, including trace-level detection of hydrogen sulfide (H₂S) and tetrahydrothiophene (THT) using µ-TCD. The platform also enables high-precision trace-level permanent gas analysis (He, H₂, O₂, N₂...), a critical requirement in the fields of hydrogen purity and carbon capture. The system is compatible with alternative carrier gases such as hydrogen, providing a reliable and efficient solution in contexts where helium supply is constrained. Greenpix’s short cycle times are especially valuable in applications like mud logging, where every second matters.

These advancements position Greenpix as a compact, flexible, and high-performance solution that is redefining performance standards in real-time gas analysis across diverse energy and industrial sectors.
