• Preventative maintenance without diverting your critical resources
• Priority scheduling over non-SureService customers
• Warranty work without the hassle of additional service calls

In general, services to be performed during maintenance include:

Gas Chromatographs

• Determine whether there are any known faults and address these either during or prior to carrying out the scheduled maintenance.
• Physically examine the instrument or analyzer:
• Carrier gas pressures are noted and checked against the original settings
•  Ancillary gas pressures and flow rates are noted and checked against the original settings
• Sample flow rate is checked against the original settings
• Change the elements of the inline stream filters as required.
• Overhaul the chromatographic valves as required.
• Ensure the sample shut-off valves operate correctly, and replace as required.
• Check that the stream selection valves are operating correctly. Replace internal stream selection valves as necessary where external stream selection is used. Advise customer of problem and corrective actions taken.       
• Check detector bridge balance and adjust as necessary. If the bridge will not balance, change detector (thermal conductivity or flame ionization detector as applicable), amplifier boards, and/or power supplies at cost.
• Check flame ionization detectors as applicable for leaks from the exhaust pipe and to ensure electrical voltages are correct.
• Using MON2000 gas chromatograph software, run and compare a chromatograph of the calibration gas (supplied by customer) with a chromatograph taken of the calibration gas at the installation or last maintenance visit
• Return GC to normal operation and ensure that it is functioning correctly.

Process Gas Analyzers

• Determine whether there are any known faults and address these either during or prior to carrying out the scheduled maintenance.
• Physically examine the instrument or analyzer.
• Repair as necessary all sample handling and conditioning components including:
• Sample system leak check
• Peristaltic condensate pumps and sample pumps
• Sample chiller temperatures and moisture sensor/trip
• Gauges, flow meters, valves, and solenoids
• Chiller impingers
• Sample pump interlocks
• Sample probe filter/gaskets
• Check and adjust sample pressures, flows, and vacuum level.
• Check sample probe and HSL temperatures/controllers.
•  Verify shelter environment
•  Validate analyzers operating to spec
•  Analyzers will be verified and as found as left data will be provided to the customer
• Detailed service report including:
•  As found / As left data
• Operating parameter deviations
• Adjustments to bring unit to spec
• Consumable items replaced
• Parts used in corrective maintenance
• System lifecycle operational recommendations
• Return analyzer to normal operation and ensure that it is functioning correctly.

Liquid Instrumentation 

• Determine whether there are any known faults and address these either during or prior to carrying out the scheduled maintenance
• Physically examine the instrument or analyzer
• Return analyzer to normal operation and ensure that it is functioning correctly
