The precisive OXS-3100 Opticla GC infrared hydrocarbon analyser real-time optical analyser capable of accurately separating the hydrocarbon components; which previously could only be performed by gas chromatograph (GC) analysers.

Using a unique wavelength-sweeping tunable filter spectrometer, fast update rates down to sub-second intervals are performed for the full C1 through C5 analysis.

Sampling is a flow-through type, suitable for a continuous, on-line, unattended operation. The hydrocarbon analyser does not require carrier gas, fuel gases, or on-site calibration gases.

The standard system configuration provides measurements of 100% of up to methane, 25% of ethane, 25% of propane, 10% of butanes and 5% of pentanes.

Other ranges and/or additional gases are available. Contact ADT for specific requirements, compounds and ranges. The Precisive OXS-3100 is available as a stand-alone analyser in two hardware configurations. Standard data interface includes a Modbus TCP/IP. An ATEX, CSA hazardous rated instrument available in Q1-2013.

Key features:

Real-time operation down to sub-second update rates
C1 – C5 alkane separation and total gas analysis
Flow-through analysis without the need for carrier-gas
Remote, unattended continuous operation
Eliminates carrier gases and other consumables
Permanent span calibration for industrial deployment
Virtually zero cross-sensitivity and high sensitivity

AI Overview BETA

The Precisive OXS-3100 Optical GC is an infrared absorption hydrocarbon analyser for on-line measurement of five alkane components in natural gas. A wavelength-sweeping tunable filter spectrometer separates methane through pentanes, providing full C1–C5 analysis with updates at intervals below one second. For natural-gas monitoring, flow-through sampling supports continuous, unattended operation without carrier gas or fuel gases.

Standard ranges: methane up to 100%; ethane and propane up to 25% each
Standard ranges: butanes up to 10%; pentanes up to 5%
No on-site calibration gases are required
Standard data interface: Modbus TCP/IP
Permanent span calibration for industrial deployment
