Sulfur Analyzers

The front panel touchscreen Graphical User Interface operating system is Linux. The system controller Auto Pilot PRO (APP) main board is running on Thermo Fisher Scientific’s proprietary OS “TaskSwitcher”. The PC based configuration and data review software, AutoCONFIG, is a Windows based system.

There are a total of 5x analogue inputs configured as 4-20mA or 0-5V.

3 are configured as density inputs, while 1 can be configured as density or flow. In case all 5 are required, then the 5^th can be configured for flow.

4x analogue outputs 4-20 mA are configured for total sulfur concentration output. Note that for dual range or multi-stream applications, the configuration of each output may vary. Consult our applications team for a more detailed explanation.

8x relay outputs rated at 10A 250VAC/30VDC and 8x solid state relay outputs rated at 1A 60VDC are configured to indicate alarm conditions and stream selection status.

12x digital inputs, of which 8 are configured for stream selection, range control, remote calibration and analysis suspension.

For a complete description of the IO please refer to our applications team.

We have both, for Ethernet and RS485 communication, respectively. MODBUS is the primary protocol for all APP ports of which we offer MODBUS TCP and Encapsulated MODBUS on the APP Ethernet port.

We provide the copper Ethernet through RJ-45. To use optical fiber for long distance communications, it is recommended to use a “copper to fiber converter.” These converters are easily sourced but not within the scope of Thermo Fisher Scientific.

Not presently, we are continuing to conduct voice of the customer interviews to determine whether this feature would be utilized by our customers in the process industry.

It is possible to access the SOLA iQ Analyzer across a network either locally or remotely. This is subject to the usual security requirements that any user will need to satisfy to access a network.

Although the APP Main board and the System Controller Board (SCB) have USB ports, the system software does not support the USB port for the communication of Modbus; an external RS485/USB converter can be used for this purpose. RS485 communication ports can be disabled. 

There is a single USB port inside the cabinet (installed on the SCB) for the purpose of storing/downloading of data.

Instrument air, for cabinet purge and solenoid activation minimum 3.8 bar(g), maximum 6.9 bar(g) pressure, 180-210 l/min (application dependent). Oil free and -40^oC dew point.

Zero Grade Air, maximum 5.5 barg 300 ml/min. For some applications, such a diesel fuels, Zero Grade Nitrogen is used in addition to Zero Grade Air.  For the SOLA Trace Analyzer, we recommend Heliox (21% oxygen balance helium) for combustion air. Consult the factory for application specific advice.

100 VAC - 240 VAC, 50/60 Hz, 18 amp circuit recommended; 18 amps maximum during warm-up cycle; 7-8 amps once achieving operational temperatures.

While the response of the touchscreen may be slightly impaired by using gloves, it does still work.

The SOLA iQ Analyzer has the same divert sample valve function driven by alarm conditions as the SOLA II Analyzer. A unique feature of the SOLA II Analyzer and SOLA iQ Analyzer is the function whereby the lamp voltage rate of change is monitored continuously. In the event of a sudden increase in lamp voltage demand (which may indicate full or partial loss of combustion), the sample divert valve is operated to prevent contamination of the optical cell.

Yes, we have taken care to place the utility and sample connections in similar positions to those of the SOLA II Analyzer. Also, the mounting tabs for the SOLA iQ Analyzer are in the same positions as they are on the SOLA II Analyzer.

The SOLA iQ Analyzer has the facility to store up to 30,000 data points which can be retrieved via Thermo Scientific AutoCONFIG Software; these can be configured as a selection of analytical and analyzer hardware performance data points. Data points can also be retrieved from the SCB board via a USB, but this requires opening the door to the electronics enclosure to gain access.  We also have storage for 30Gb of data incorporated into the System Controller Board, accessible by the front panel GUI or remotely using VNC viewer.

The SOLA iQ Analyzer performance is equivalent to SOLA II Analyzer.

No, it is similar.

No, it has the same injection valve as the SOLA II Analyzer. We tested other types of valves which are claimed to have lower maintenance requirements, but the analytical performance and reliability was not acceptable.
