Antek lab instruments provide reliable, precise elemental analysis for total nitrogen and sulfur, speciated nitrogen and sulfur, fluoride, chloride, and bromide.
Antek’s 40-year foundation of technology innovation continues as part of the PAC family. Antek products are recognized by global regulating bodies, leading scientific research institutions, and process laboratories as the instrument of choice for selective multi-element detection.
Antek also includes process analyzers for monitoring total nitrogen and sulfur in liquids, gases and LPGs and determination of nitrogen, sulfur, total hydrocarbon, and aromatics for the quality assurance for CO2.
Cambridge Viscosity (CVI), with over 25 years of experience, is a known global leader in small sample viscosity.
Its innovation includes a patented sensor technology, which sets it apart from the rest of the industry. This patented, proprietary electromagnetic-based sensor technology utilizes only one moving part, a piston, driven electromagnetically through fluid in a small measurement chamber. A deflector, positioned over the piston, moves fluid into the measurement chamber, while two coils move the piston back and forth at a constant force. Proprietary circuitry analyzes its two-way travel time to measure absolute viscosity. Every CVI viscometer uses one of these sensors, which is key to running an efficient process since the same technology is utilized both in-line and in the lab.
Originally established in 1931, Herzog has a comprehensive line of laboratory instruments for testing atmospheric and vacuum distillation, flash point, vapor pressure, bitumen properties, cold flow properties, viscosity and other physical properties of materials.
Herzog early on pioneered efforts to automate traditional manual methods of testing in order to save manpower and eliminate user errors. Herzog also took the lead in efforts to develop and standardize new, alternative lab methods where the hallmarks were low sample volume requirements, achieving faster results, higher precision in analysis and greater ease of use by operators with lower general skill levels.
With more than 35 years of experience, ISL is a recognized leader in the field of physical testing equipment of petroleum products. ISL technology includes self-contained automated analyzers, such as mini distillation, flash and fire point, viscosity, cold properties, evaporation loss; lubricants and asphalts testing equipment.
ISL’s story began when a group of engineers and scientists in the North of France, the heart of the country’s petrochemical industry, began developing automatic instruments for use in the petroleum industry.
By the mid 1970s the ATPEM trademark was born, and rapidly became a worldwide leader in automatic petroleum testing instrumentation. In 1986, ATPEM was reorganized and became ISL, and was acquired by PAC in 1999.
Phase Technology was founded in 1989 by Charles and Norman Tsang and has grown organically through the design and engineering of highly innovative and functional products, dedication to research and development and precise cost-effective manufacturing capabilities. Phase has an outstanding reputation as a leader in the cold-flow properties testing industry due to consistent introduction of new innovative products and continual improvement in the quality, design and capabilities of its offerings.
PetroSpec is the leading provider of dependable, portable, high-quality spectroscopic analyzers for measuring the chemical and physical properties of fuels. PetroSpec instruments are dedicated to field compliance testing for gasoline and diesel, helping end users meet such ASTM standards. PetroSpec analyzers were developed to support the USEPA Reformulated Gas program. They produce fast and accurate analyzers for hydrocarbon fuels, bio-based fuels, and petroleum products.
Advanced Sensors is the leading global supplier of Oil in Water (OiW) analyzers to the Oil and Gas Industries, providing innovative solutions that guarantee analyzers are self-cleaning, reliable and durable. Accurate measurement ensures process and environmental control and offers early warning indicators of leaks and discharges.
Advanced Sensors combines numerous measurement technologies, such as ultrasonics (the cornerstone of the zero routine maintenance Oil in Water analyzers), fluorescence, video microscopy, optical spectroscopy and optical spectrometry, to ensure analyzers stay clean and provide precise readings, thus offering complete solutions relevant to the users specific requirements.
