Fast and Precise CFPP Testing of Diesel Fuels With Error-Free Detection


Anton Paar (Austria) introduces Callisto 100, a fully automated, compact, stand- alone CFPP tester operated by touchscreen. The tester contains all required components according to the standard method. Testing and results are in full compliance with ASTM D6371, EN 116, EN 16329, IP 309 and JIS K2288. In addition, Callisto 100 can be used for manual cloud and pour point measurements.


Based on more than 30 years of Anton Paar’s experience in Peltier element technology, Callisto 100 comes with a newly


developed state-of-the-art Peltier element concept which allows the connection of a methanol-free cooling system. It ensures outstanding homogeneity of the cooling jacket, which is the most critical and decisive parameter for a correct CFPP value determination.


For easy and intuitive operation, Callisto 100 comes with pre-programmed standard test methods and the possibility to create and store up to 90 individual user programs. The large colour display indicates the sample and jacket temperature in real time and provides additional graphical information about the aspiration and back flow times to observe the temperature behavior of the sample during the test.


Callisto 100 has a minimum downtime for high sample throughput. Once users have prepared their second complete filtration unit and put it into the storage place at the rear of the instrument, the instrument is ready for the next test run within seconds. To make the cleaning of the pipette as easy as possible, a programmable automated cleaning routine can be initiated at the push of a button. In addition, Callisto 100 is entirely maintenance-free.

Pioneering a New Age of Precision in Vapour Pressure Testing


AMETEK Grabner Instruments (Austria) has extended its vapour pressure tester product portfolio with the launch of a new automatic tester for low-volatility measurements. Grabner developed the MINIVAP VPXpert-L to automate the manual ASTM D2879 Standard Test Method for Vapour Pressure by Isoteniscope used by the chemical industry. The MINIVAP VPXpert-L analyser measures gasoline, jet fuels, solvents and chemicals as well as food, flavour and fragrance products with vastly improved precision. The analyser is optimised for a pressure range from 0.1 to 100 kPa and shows a measuring repeatability better than 0.1 kPa.


Government regulations mandate the measurement of the vapour pressure of virtually any liquid manufactured, stored or shipped to ensure transportation safety and


to protect the environment. The MINIVAP VPXpert-L is the first completely automatic analyser that accurately tests fuels and chemicals down to 0.1 kPa vapour pressure in a temperature range from 0 to 120°C. The pressure range of this new tester is limited to 100 kPa, which results in an optimized measuring repeatability of less than 0.1 kPa. The instrument requires only 1 mL of sample per test, eliminates the need for vacuum pump and manual filling, and yields results within minutes.


“AMETEK Grabner Instruments is the recognised leader in vapour pressure testing. With its introduction of the MINIVAP VPXpert-L, Grabner paves the way for a new era in vapour pressure testing,” explains Oliver Sauer, Head of Marketing & Sales at AMETEK Grabner Instruments. “In terms of precision, the new instrument is about five times more precise when compared with other testers.”

“With this analyser, we are able to meet two key market requirements. First, we fulfill the demand of the petroleum industry for higher precision in routine gasoline and jet fuel testing. And, we offer a solution for the chemical, flavours and food industries, which have a specific need for low-volatility testing.”

The MINIVAP VPXpert-L includes all standard vapour pressure methods for testing fuels and incorporates new static methods for testing chemical compounds. These new “VOC”-methods measure the absolute vapour pressure based on the static Triple Expansion Method and yield results equivalent to the static ASTM D2879 Isoteniscope method.


While experienced personnel are needed to operate an Isoteniscope, the VPXpert-L is easy to use. When the sample is connected to the instrument, a fully automatic measurement can be started immediately. To prevent composition changes of chemicals during the test, a sample evacuation is not required. Instead, dissolved and entrained air is automatically removed from the measurement result. Cross contamination between low volatile samples is minimised through a clever combination of high-quality Sampling Pro valves and automatic rinsing. To ensure proper sample outgassing and to reduce equilibrium time, a sample shaker is installed in every unit.


Rapid Molecular-Level Characterisation of Non-Volatile Components of Crude Oil

Crude oil is an extremely complex mixture of hydrocarbons and other chemicals which varies widely depending on origin, age, maturity and how the petroleum was formed. Detailed chemical analysis can produce ‘fingerprints’ that can be used to determine the source of the petroleum. High boiling hydrocarbons as well as highly polar compounds are not accessible to traditional GC/MS analysis but can be easily and rapidly accessed with Bruker’s LDI technology.

Crude oil samples can be measured by LDI without any purification by dissolving 10 mg of oil in 990 µL toluene. 1 µL of this solution is applied to a stainless steel target and simply dried for 15 min at room temperature. Following acquisition at a mass resolving power of 450,000 (m/z 400), molecular formulae are automatically calculated for each peak in the mass spectrum and grouped by classification.


Bruker’s unique eXtreme resolution technology is essential for resolving and calculating the correct molecular formula of each chemical peak in these types of complex samples. Applying statistically based principal component analysis enables the differentiation of crude oils based on their different chemical qualities. This capability can be vital for detecting even slight differences in reservoirs or temperature or pressure that cannot be detected by any other analytical means.
