How does the 490-GC Micro-GC Work

Complete miniaturised GC system:• 1 up to 4 complete GC channels

Each GC channel is a separate GC:• Silicon micro-machined injector• Oven with analytical column • Micro-machined Thermal Conductivity Detector (µ-TCD)• Pneumatics• Electronics

Each channel is tuned for a specific part of the sample

On Board Data Handling

Built into the 490-PRO:• Peak integration• Peak identification• Peak calibration• Peak grouping

This means that for routine measurements:• Full autonomous operation (no operator required)• No external data handling software required • No PC needed to generate results

20

490-PRO – Fully Automated Operation

Sequential measurement runs that include:• sample type • valve/sample position• flush time• calibration level

Calibration and/or verification analysis• after a desired # of samples • based on a specific time• on demand via remote command• automatic (re)calibration if verification values “fail”

21

490-PRO – Fully Automated Operation

Stream selection and control:• Electrically actuated multi-position valves • Solenoids based stream selectors

Remote Communication:• MODBUS • Digital input

22

Standard Functionality

• Validation of• Verification samples• Sample streams• Calibration samples

• Calculation parameters:• Multi channel normalisation. Optional a bridge component• Add estimated concentrations for non detected peaks• Convert acquired analog input signals to functional values, ex.

sample flow• Definable alarms to:

– activate a relay – store results in MODBUS registers

• Definable 4-20 mA signals

23

Additional available Functionality in 490-PRO

“Energy meter”• According to ISO 6976, ASTM D3588, GPA 2172 and GOST

– calorific value– relative density – compressibility factor

35 day logging:• according API (chapter21)

Serial output:• MODBUS communication

Note: requires licenses

24

MODBUS (490-PRO is a MODBUS “slave”):

Communication:• Serial: RS-232 or RS-485• Ethernet TCP/IP

Commands from Industrial Network:• Start analysis type

– Run, calibration, verification, column conditioning, method parameters

• Stream selectionInformation to Industrial Network:

• Instrument status • OBDH results• Application results
