DPS InstrumentsModel Companion 2 -Portable Gas Chromatography System

SHARE
The Companion 2 Portable Gas Chromatography (GC) System is designed for remote and mobile applications, providing comprehensive analytical capabilities in a compact format. This portable GC features modular designs with integrated accessories, allowing for versatile configurations tailored to specific applications. It supports a range of detector types, including BCD, FID, FPD, HID, NPD, PID, and TID, with precise temperature control options extending up to 325°C. The system is equipped with electronic pressure controls, offering resolution down to 0.1 kPa, ensuring accuracy throughout the analytical process. It features a unique fluidless column oven with efficient inlet and outlet temperature profiles that streamline peak separation. The Companion 2 also comprises built-in air, headspace, purge & trap concentrators, and can handle multiple samples using automated DPX control software. With a durable, compact, lightweight design, it ensures robust operation while maintaining sample integrity through sophisticated contaminant control mechanisms.
