ANALYTICAL INSTRUMENTATION
Spectroscopy. Seeking to simplify and speed up laboratory operations, the characterisation of base oil by advanced spectroscopic and chemometric tools was described, as well as the application of this new approach to catalyst research and development.
In order to avoid contamination in recycling processes the application of spectroscopy in mixed municipal waste was described. This was followed by an explanation of the ways in which analysis with thermo-rheological tools enables the optimisation of extrusion and blending.
The next session was chaired by Dr Anton Ginzburg from KU Leuven in Belgium, and focused on Recycling. The concept of circular plastics (Truecircle initiative) was discussed, highlighting the challenges and opportunities in chemical and mechanical recycling. This included examples in polyolefin-based materials for food- and non-food applications. Participants asked about value creation and energy efficiency as well as bad publicity relating to plastics.
The group-type analysis of recycled feedstock was then described with the determination of trace level impurities by GC and comprehensive GC×GC. The audience was particularly interested in how the EPED detector compares to the conventional AED detector.
Novel concepts for the identification and quantification of hydrocarbon streams originating from pyrolysis were presented, using several GC techniques and comprehensive GC×GC. A particular focus was given to GC coupled to a novel vacuum UV detector in comparison with conventional detailed hydrocarbon
analysis via GC-FID and GC×GC.
In the final presentation of the session, the challenges relating to the analysis of malodour compounds using multi-dimensional GC×GC were described. This prompted questions about the types of waste samples that were analysed and the sample preparation protocol.
After the break, Dr. Beate Gruber from BASF in Germany chaired a session on Instrumental/ Method Development. Recent Micro GC developments, such as operation with a phone or tablet, were described for out-of-lab and process applications. Bio-oils obtained from lignocellulosic biomass pyrolysis have the potential to replace petroleum-based fuels, but they are complex and contain water, so an analytical method was described. This couples supercritical fluid chromatography with ion mobility spectrometry - mass spectrometry (SFC-IMS-MS) for bio-oil characterisation.
Historically the analysis and certification of gasoline, jet fuel, diesel and biodiesel blends has required the use of numerous analytical technologies and methodologies, which can be costly and complex. A platform-based approach to fuels analysis that employs a single, automated analytical approach using GC-VUV was therefore described.
Dr Melissa Dunkle from Dow Benelux then chaired a session which was a short course on GC×GC in Petrochemical Applications and Data Evaluation. Melissa delivered a presentation on diverse detection techniques in GC×GC, which was followed by Anupam Giri who described the application of GC×GC in a variety of petrochemical applications.
Summary
Whilst it was unfortunate that PEFTEC 2021 had to be a virtual event, Marcus Pattison believes that it was an outstanding success. “As a free online event, we were able to bring PEFTEC to a much wider audience than ever before. The usual participants from the refinery and petrochemical sectors were present, but we also welcomed much broader global participation with more researchers, students, laboratory technicians and process managers.
“This year, there was also a marked increase in the numbers of people working on environmental issues such as waste management and recycling, and we anticipate this being a growing theme as we plan for PEFTEC 2022.
“Nevertheless, we have now issued an open invitation to all interested parties for ‘Topics of Concern’ – if anyone would like to suggest which subjects PEFTEC 2022 should address, or if they would like to be considered for the delivery of a presentation, we would be delighted to hear from them.”
PEFTEC 2022 will take place on 8th & 9th June in Rotterdam, and as a hybrid event, it will offer the advantages of a physical event at which people can meet face to face, with the benefits of the same virtual platform so that anyone who is unable to attend in person, can do so online.

Advanced and rugged enclosure makes PEMS ideal for NRMM and HDV harsh environment real world emissions monitoring
Horiba has launched an advanced rugged enclosure for its versatile OBS-ONE portable emissions measurement system (PEMS), enabling it to be used for the in-service monitoring of real world emissions (RWE) of combustion engine powered non-road mobile machinery (NRMM) in real-life operational and often harsh environments.
Called the OBS-ONE-RE, the enclosure is a feature-rich system in its own right and enables the OBS-ONE – as trusted the world over by leading OEMs of light- and heavy-duty vehicles for establishing real-driving emissions (RDE) and in-service conformity – to be used for monitoring the exhaust gases of machinery such as diggers, quarry vehicles, snowmobiles, inland water vessels and portable power generating sets.
Les Hill, Manager of HORIBA’s Global Product Planning Group and a member of a number of RDE working groups, comments: “In 2016, the European Commission published the EU Stage V legislation for Non-Road Mobile Machinery. Subsequently, in 2019, the in-service monitoring of NRMMs became mandatory, to monitor for discrepancies between engine-under-test emissions established in the laboratory and real-world emissions when the engine is installed in equipment and in use.”
Launched in 2014, HORIBA’s OBS-ONE measures concentration levels of gaseous emissions – specifically carbon monoxide (CO), carbon dioxide (CO2 nitrogen dioxide (NO2
The OBS-ONE-RE features high endurance and reliable springs that protect the OBS-ONE from shock and vibration in all three axes. In addition, the OBS-ONE-RE is weather-proof, has dust filters and has a cooling system that maintains a consistent internal temperature; enabling the OBS-ONE-RE to operate over the range -7 to +40o
C.
Built-in Wi-Fi allows the OBS-ONE-RE to be operated and monitored remotely, enabling the NRMM driver to concentrate on the vehicle or machinery operation.
This rich feature set makes the rugged enclosure the perfect solution for protecting the OBS-ONE from the harsh environments in which many NRMMs, and some HDVs operate and which must now be monitored under industry regulations.
Lewis George, Product Design Engineer of HORIBA UK’s R&D department, comments: “The OBS-ONE-RE is the result of extensive research, development and verification, including testing on the shaker rigs of certified test houses and on various NRMM vehicles, to ensure the product’s durability and robustness. Most importantly, the OBS-ONE maintains a stable response within tolerances appropriate for certification.”
George goes on to explain that HORIBA is already the go-to company for LDV RDE PEMS and for HDV in service monitoring PEMS, adding: “Now we’ve risen to the challenge of taking our trusted and reliable PEMS out into the harshest environments, which will be useful for product development purposes as well meeting the industry’s requirements for in-service monitoring post product launch. Also, our solution offers easy onsite customisation, ensuring monitoring can be performed reliably while ensuring the safety of those operating the OBS-ONE.”
Those developing NRMMs or HDVs likely to be used in harsh environments are encouraged to contact Horiba for further information on the latest RWE regulations, likely changes to regulations in the future and how Horiba’s proven and trusted OBS- ONE and the Rugged Enclosure can help them achieve compliance and de-risk their programmes.
