Product catalog summary
Specifications Overview
The R490 M MicroGC is designed for rapid analysis of Biomethane quality, including certified Metrology SHV and THT. It is a compact system mounted in a 5U 19" rack, suitable for standard analysis bays, and performs measurements every 3 minutes. The device is delivered ready for use with an acceptance report and includes a complete analytical method.

Configuration and System Settings
The system features two specific channels for Biomethane quality analysis and a third channel for THT or other compounds. It includes a computer with embedded software for automation, piloting, control, integration, and calculation, with Modbus tables. The Soprane software on the embedded PC allows direct connection for maintenance and remote control via Ethernet.

Injector and Oven
The injector is miniature with no moving parts, offering variable injection volumes from 1 µL to 10 µL, programmable by software, and is heated. The oven is isothermal, adjustable from 40 °C to 180 °C.

Detector and Quantification
The micro catharometer (TCD) detector has two channels with an internal volume of 200 nL per channel and four filaments. The quantification limit is a few ppmV, with a measuring range from ppmV to 100% and SHV from 9 to 12.6 kWh/m3.

Performance and Adjustment
Repeatability is less than 2% RSD at 25 °C. Adjustments are made using standard cylinders on a Biomethane mixture for SHV, with an average of three consecutive analyses. Measurement uncertainty is class A for SHV, Wobbe index, and density, with specific tolerances for CO2, O2, H2S, and THT.

Carrier Gas and Sample Handling
Helium with 99.9999% purity is used as the carrier gas. The sample inlet features a Swagelok stainless steel connection with an integrated high-capacity dust filter, supporting pressures from 0.1 to 1 bar rel.

Environmental and Communication Features
The device operates in relative humidity from 0 to 95% and temperatures from -10 °C to 40 °C. Communication options include a TCP/IP Ethernet port, RS485 Modbus, and optional 4-20 mA outputs.

Automation and Data Management
Automation includes automatic start on power-up and configurable analysis delays. Data can be stored on the embedded computer or a remote server.

Documentation and Physical Specifications
Documentation includes specific manuals in English and acceptance documents. The device dimensions are L482mm x H225mm x W464mm, weighing 17 kg, with a power supply of 100-240 Vac 50-60 Hz 6.3 At.
