Analytical Instrumentation Vapour Pressure Testing at its Best
In 2007 eralytics started a new era of petroleum analysers, being the fi rst manufacturer to offer instruments which featured colour touch screens and modern industry PCs with USB and Ethernet interfaces. This ultimately changed the way lab technicians interact with their analysers.
Today, eralytics is proud to announce its next generation of analysers for the petroleum industry. They feature a highly rugged 8-inch touch screen where you can tap, swipe and scroll through your measurement data like you are used to from your smartphone. The new front USB connectors further speed up data downloads from the instruments, which makes operating eralytics analysers another notch easier and faster. Naturally, also the new generation meets the familiar eralytics benchmark motto: “Performance you can rely on”, which stands for full compliance with the latest international standards, unrivalled precision and ultimate durability.
The fi rst of eralytics well-established analysers to be available in this next-generation design are the vapour pressure testers of the series ERAVAP.
For standard vapour pressure tests of all kinds of fuels, solvents and crude oils with maximum accuracy we offer the model ERAVAP EV10. This instrument is equipped with a high-precision pressure transducer, which guarantees long-term stability and best-in-class repeatability (0.15 kPa for pure solvents at 37.8°C) in the pressure range of up to 10 bar (1000 kPa). For the measurement of high-pressure LPG samples eralytics offers the extended pressure range model ERAVAP EV20, which allows vapour pressure tests at up to 20 bar (2000 kPa).
Both models are available as all-in-one solutions equipped with a built-in shaker motor. They provide fully automated vapour pressure testing of gasoline, crude oil and LPG according to the latest international standards such as ASTM D5188, D5191, D6377, D6378, D6897, EN13016 1+2, etc. Additionally ERAVAP’s capabilities can be extended with eralytics’ unique special application modules: -) Low VP Module for the measurement of e.g. chemicals with vapour pressures as low as 0.1 kPa within an extended measuring range of -99 to 300°C. -) High Viscosity Module with heating for the inlet and outlet of the analyser up to 70 °C to allow measuring of e.g. crude oil samples with an extremely high viscosity at ambient temperature. -) Low Temperature Module to perform vapour pressure measurements of e.g. gasoline samples down to -20°C (-4°F) With all the above features eralytics’ new generation vapour pressure tester family remains the most comprehensive one on the market, tying in with our motto: ERAVAP - Vapour Pressure Testing at its Best.

ERAVAP ONLINE is the counterpart to eralytics’ laboratory vapour pressure tester ERAVAP. Its core is based on the very same measurement cell as the laboratory instrument uses with additional measures to further increase the already excellent durability of the lab instrument. This alikeness of the two measurement cells leads to identical results on both instruments rendering error-prone correlations unnecessary.
ERAVAP ONLINE handles up to fi ve independent fl uid streams which can be freely confi gured as sample, quality control or cleaning agent streams. The measurement results are output over MODBUS or analog lines. Confi gurable digital I/Os can be used for further communication if needed.
ERAVAP ONLINE is delivered with a set of two measurement cells which store all important calibration parameters directly. Therefore the recalibration procedure interrupts the measurement sequence for only a minute – the time needed to exchange the two cells. Afterwards the spare cell is recalibrated off-site.
With available test methods for crude oil (ASTM D6377), gasoline (ASTM D6378) and LPG (ASTM D6897) the ex-proof ERAVAP ONLINE analyser is the ideal solution for a wide variety of different applications in your process environment. Whether it is quality control or fuel blending ERAVAP ONLINE is your analyser of choice.
The Fastest Side of Flash Point Testing

After the great success of the single position fl ash point tester ERAFLASH, eralytics is happy to introduce the unique 10 position autosampler version ERAFLASH S10. The covered methods ASTM D7094 and ASTM D6450 are both continuously closed cup methods and therefore intrinsically safe in usage. There is no risk at all of a fi re in the lab as any fl ame is automatically extinguished due to a lack of oxygen.

Using these safe methods for our 10 position fl ash point tester helps to overcome any preconception lab managers might have against auto sampler fl ash point testers in general due to safety concerns. In contrast to Pensky Martens testers a sample volume of only 1 or 2 ml is needed which is never exposed to an open fl ame.
Since December 2013 the fl ash point method ASTM D7094 is also accepted as an offi cial alternative to ASTM D93 for fuel specifi cation testing according to ASTM D396 (Fuel oils), D975 (Diesel fuel oils), D2880 (Gas turbine fuel oils), D3699 (Kerosene) and D7467 (Diesel Fuel Oil, Biodiesel Blend B6 to B20).
With its unrivaled temperature range of -25 to 420 °C (-13 to 788 °F) ERAFLASH S10 cannot only be used for fuel specifi cation purposes. It is also an extremely cost effi cient tool from the fl avours and fragrances industry all the way to big used oil testing facilities. All industries profi t from the small sample volume and the patented Peltier Boost Technology (PBT) allowing for unmatched heating and cooling rates and therefore for shortest turnaround times on the market.

eralytics is proud to release a new instrument for the measurement of oil-in-water. Ecology meets economy in ERACHECK ECO by combining an advanced optical fi lter-based measurement technique with the ecologically safe extraction solvent cyclohexane. The use of a cost-effi cient measurement technology in combination with the low-cost solvent cyclohexane gives you the most economical oil-in-water tester available today.
Adding ERACHECK ECO to eralytics’ product line is a huge step towards a cleaner environment. But let’s take a look at the big picture and start from the beginning: In 1989 the Montreal protocol decided to forbid all CFC solvents by 2020 at the latest due to their harmful effects on the ozone layer. These types of solvents were used to measure one ecologically important parameter called oil-in-water – a closely monitored value to decide if waste water or discharge water shall be allowed to be disposed as is or if it needs to be further purifi ed to be safe for the environment.
After 1989 the US Environmental Protection Agency (EPA) switched from the previous IR method ASTM D3921, which used a CFC solvent, to a gravimetrical method called EPA 1664B. In Europe people shifted to gas chromatography using method ISO 9377-2. Both techniques suffer from several drawbacks in comparison with the IR methods. They are more time consuming and/or less accurate and repeatable.
There was and still is a need for an easy-to-operate measurement technique which offers all the advantages of the IR methods but without the need for a CFC solvent such as Freon 113. ERACHECK PRO was the fi rst oil-in-water tester released by eralytics in 2008 to offer that. It uses a high-end quantum cascade laser light source which allows measuring extracted oil in the ecologically friendly solvent cyclohexane with highest precision in the low sub-ppm range. Quantum cascade lasers are highly effi cient, but on the downside, they are also a pretty costly technology. So eralytics engineers looked into fi nding a measurement technique that was considerably more cost-effi cient, without compromising on the benefi ts of ERACHECK PRO.
In hindsight we can say that this was no easy task at all. But we succeeded in building an instrument based on optical high-tech fi lters which can measure oil-in-water down to a concentration of 0.5 mg/l. We call it ERACHECK ECO. It still uses the eco- friendly solvent cyclohexane and is the most economical highly precise analyser available on the market today.
Naturally, we continue to offer ERACHECK PRO, because it reaches an even lower limit of detection. Therefore, the PRO model remains the instrument of choice for specialised high-end applications, whereas ERACHECK ECO is designed to be the new sturdy workhorse for oil-in-water testing.
Upgrade your oil-in-water testing to the next level in terms of precision, ease of use, measurement speed and environmental friendliness with ERACHECK ECO.
