PAC is a worldwide leader in laboratory analysis equipment. With a product portfolio of over 200 testing instruments, it delivers cutting-edge technology and R&D resources to support its core technologies in diverse applications like: gas chromatography, elemental analysis, physical properties, fuels composition, viscosity and laboratory automation.

Cloud Point: in petroleum products and biodiesel fuels, the temperature of a liquid specimen when the smallest observable cluster of hydrocarbon crystals first occurs upon cooling under prescribed conditions.

Pour Point: in petroleum products, the lowest temperature at which movement of the test specimen is observed under the prescribed conditions of the test.

Cold Filter Plugging Point: the lowest temperature at which a fuel will give trouble-free flow in certain fuel systems.

Freeze Point: the aviation fuel temperature at which solid hydrocarbon crystals, formed on cooling, disappear when the temperature of the fuel is allowed to rise under specified conditions of test.

Our density analyzers will help your laboratory efficiency achieve the highest level of quality compliance. Accurately measure density in light and mid distillates, heavy oils, food and beverage applications or mobile labs.

Atmospheric distillation, vacuum distillation and micro-distillation measured by our automated analyzers which correlate with standard methods.

PAC offers reliable, precise elemental analysis that is applicable to a variety of industries. The innovative MultiTek® elemental analyzer uses a uniquely efficient process that includes combustion ion chromatography (CIC), ultraviolet fluorescence (UVF), and our chemiluminescence (CLND) technologies to measure total sulfur, total nitrogen, and/or halides.

Fuel composition analysis is critical to maintaining fuel quality, regulatory and environmental compliance, and consistency of performance.  PAC analyzers measure: jet fuel or diesel thermal oxidation, gasoline, diesel fuel and blending streams, ethanol in gasoline, ethanol purity, and fuel lubricity.

PAC provides a range of liquid and gas chromatography turnkey solutions for petroleum, petrochemical and natural gas industries. Determination of boiling range distribution by gas chromatography is one of the most commonly used means of characterizing hydrocarbons and their different formulations. It is fast, reliable, and fully compliant with multiple international simulated distillation methods.

Determine the temperature at which a particular organic compound gives off sufficient vapor to ignite in air. Measuring a flash point requires an ignition source. At the flash point, the vapor may cease to burn when the ignition source is removed.

Measure the viscosity of a fluid by determining its resistance to gradual deformation by shear stress or tensile stress, all while requiring a very small sample of fluid.
