ANALYTICAL INSTRUMENTATION Lubricant Analysis Innovative lubricant testing solutions


Savant Group members, Savant Labs and Tannas Co., showcased their latest innovations in lubricant and fl uid performance testing at this year’s Gulf Coast Conference (GCC) in Galveston, TX. Focusing on the rapidly evolving needs of hybrid and electric vehicle technologies, the companies highlighted their state-of-the-art instrumentation, quick turnaround testing services, and pioneering methodologies that continue to shape the industry.


Savant Labs boasts an impressive portfolio of analytical technologies, ranging from conductive deposit and corrosion analysis to a wide range of standard and customised lubricant evaluations. Complementing this, Tannas Co. also specialises in the development of advanced laboratory instrumentation, enabling users to conduct high-level testing capabilities in-house.


Among the key technologies is the TanEV Conductive Deposit Test (CDT™), ASTM D8544, developed specifi cally for hybrid and electric vehicle lubricants. This method assesses the likelihood of lubricants forming conductive deposits on copper motor windings, connectors, and other electrical components at high temperatures. Another highlight is the TanEV Wire Corrosion Test (WCT™), ASTM under development, a fully energised procedure operating at up to 150°C. The test monitors changes in circuit conductance over 72 hours, linking


resistance variation with the extent of corrosion. A range of metallic materials can be tested using this method.


Savant also showcased the Quantum™ Pro Oxidation Tester (ASTM D2272 & D2112), which measures oxidation stability by exposing samples to oxygen in a stainless-steel pressure chamber under controlled temperature and pressure conditions. The pressure changes indicate antioxidant depletion and signal the test’s completion. Additionally, visitors will see the TBS™ 3000 HTHS Tapered Bearing Simulator Viscometer (ASTM D4683, D6616, CEC L-36-90), a high-temperature, high-shear rotational viscometer that evaluates a fl uid’s thin-fi lm performance under dynamic conditions. This instrument provides highly precise viscosity measurements for both fresh and used fl uids across a range of temperatures and shear rates.

Elemental Analysis


Analysis of total fl uorine, chlorine, and sulfur in aromatic hydrocarbons with the Xprep C-IC


a boat introduction system. While effective, this approach can be slow and less reproducible, especially at low concentrations. Direct liquid injection offers a modern alternative—eliminating intermediate steps, allowing larger sample volumes, and improving both sensitivity and throughput.


Analysis of halogens in aromatic hydrocarbons is essential in the petrochemical and chemical industries. Even trace amounts of fl uorine, chlorine, and sulphur can disrupt both upstream and downstream processes, leading to issues such as catalyst poisoning and/or equipment corrosion. From an environmental perspective, excessive halogen content in fuels can result in harmful emissions.


The ASTM D7359 standard provides a reliable method for determining total Fluorine, Chlorine, and Sulfur in aromatic hydrocarbons, covering concentrations from 0.10 to 10 mg/kg. The technique is based on oxidative pyrohydrolytic combustion, where halogens and sulphur compounds are converted into HF, HCl, and SO₂/SO₃, absorbed in an absorber solution, followed by analysis by Ion Chromatography (C-IC). This approach ensures sensitive and accurate results at trace level and higher concentration levels.


Traditionally, samples are introduced into the combustion furnace using

TE Instruments developed the Xprep C-IC, a compact, fully automated system for Combustion Ion Chromatography. It is the only confi guration capable of handling both direct liquid injection and boat introduction in one analyser setup. This gives laboratories maximum fl exibility in method selection.


Direct injection, supported by the Liquids Module and Vectra Autosampler, allows up to 250 µL of sample to be introduced at a controlled rate. This results in faster introduction, lower blank values, and a signifi cantly improved performance for trace-level applications such as aromatic hydrocarbons and ultrapure chemicals. Calibration tests show superior linearity (R² > 0.999), lower detection limits, and better repeatability compared to conventional boat introduction methods.


Conclusion By combining ASTM D7359 with the Xprep C-IC, laboratories can achieve accurate, effi cient, and fully automated analysis of Fluorine, Chlorine, and Sulphur in aromatic hydrocarbons. The analyser design enables fl exibility and performance, ensuring reliable results for routine quality control and compliance testing.

Better lab project management


Nowadays, the majority of industrial projects are subject to delays and cost over-runs. Usually, these result from the tendency to award projects to the lowest bidder. But environmental oversight as well as multiple governmental, environmental and social reviews can also cause signifi cant amounts of delays. In extreme cases, these can add more than 10 years to the length of a project.


Therefore, cost management becomes an even more pressing concern for all parties involved. Relatedly, parties tend to pursue increasingly complicated terms and conditions in an attempt to minimise risk, adding greater regulatory burden. As a result, risk management may be weakened beyond the basic requirement for the project to complete test runs before it starts to generate an income.


Of course, such risks are far higher in zones of hostility or instability, and any inability to certify products as ‘fi t for purpose’ automatically causes product prices to drop signifi cantly. We have seen price drops of 90% due to minor contamination or potential disposal costs due to the need to dispose of off-spec materials found at sites.


As such, confi dence in product certifi cation results is an absolute essential and labs must have contingency plans in place should they become operationally compromised via fi re, explosion or contamination. Relatedly, contingency planning is essential to ensure that reliable product certifi cation restrictions are well managed and technically feasible. Insurers also have signifi cant interests in risk management practices and risk contingency policies. Contamination clean-up is often a very large cost consideration for insurers. Violent disruption, too, is now an additional risk being carefully evaluated in many parts of the world.


The team members at R&E Owen Laboratory Exerts, have direct experience in dealing with the above risks and ways in which they might be best managed, having worked in several war zones and over 74 countries to date. We directly work out of the UK, Europe and Canada. We are a reliable and knowledgeable entity with a wealth of useful experience over 50 years, including a real awareness of both price sensitivity and risks.
