Agilent 990 MicroGC G3588A

The Agilent 990 MicroGC (G3588A) is a compact, manufacturer-configured micro gas chromatograph designed for fast, laboratory-quality compositional analysis of gases (for example natural gas, biogas and process gases). Each analytical channel is a miniaturized GC with electronic pneumatics control and a micro-thermal conductivity detector, enabling continuous or unattended at‑line, in‑line or field operation and rapid results in minutes.

Key Features:

• Configurable 1–4 independent micro‑GC channels (dual cabinet expandable to four channels).
• Micro‑machined thermal conductivity detector (µTCD) on each channel.
• Dynamic Electronic Gas Control (DEGC) injector with a 10 µL sample loop.
• Carrier gas options: He, H2, N2 or Ar (manufacturer recommends high‑purity gases, e.g., 99.999%).
• Isothermal operation with optional backflush capability to shorten cycle times; designed for fast analyses (results in minutes).
• Operating ambient range 0–50 °C; certified to operate up to 2,000 m altitude.

Advantages:

• Delivers fast, on-site, lab-quality gas composition results in minutes—useful for natural gas, biogas, refinery and process monitoring.
• Very small footprint and low resource use: Agilent states substantially lower power and carrier‑gas consumption (approximately 10% versus conventional GCs), reducing operating cost and logistics.
• Modular, exchangeable channels and electronic gas control enable quick reconfiguration and field servicing to maximize uptime and application flexibility.
• Inert (Ultimetal‑treated) sample path improves detection limits and supports demanding analyses (including low‑ppm sulfur measurements).
