Analytical Instrumentation New cloud point option for diesel fuel analysis


Cloud point is the temperature at which wax crystals are first observed in the liquid sample upon cooling under prescribed conditions. It is an important physical property for estimating diesel fuel performance under cold temperatures since wax formation can cause flow performance issues such as fuel filter clogging.


The ASTM D975, Specification for Diesel Fuels, specifies the manual cloud point testing method D2500 as the referee method. Although the manual method maintains its significance from its history and its position as the referee method, it is a heavily time/labour consuming test, and the judgement of the cloud point is highly dependent on the operator’s skill which often times can result in poor precision and accuracy.


In the latest version (D975-17a), the ASTM committee has approved the addition of D7683 Standard Test Method for Cloud Point of Petroleum Products (Small Test Jar Method) as an alternative to the manual method.


Tanaka Scientific’s MPC models which automatically run cloud point tests according to D7683 offers simple and precise measurements. Compared to the manual method, testing time is reduced by more than 50%, and sample volume by 90%. Pour point can also be measured simultaneously according to ASTM D6749 on the same sample.


Precision is significantly improved due to automation. Furthermore, the MPC models allow for 1 °C test intervals for pour point and 0.1 °C intervals for cloud point which helps the user achieve even more precise results. Model MPC-102S uses advanced refrigerant-free cooling technology without the need for connection to an external refrigerated chiller which saves lab space and eliminates maintenance of refrigerant and coolant.

45201pr@reply-direct.com Improve traceability and


profitability in fuel testing PAC proudly introduced the new Phase Technology DFA-70Xi. A 4-in-1 diesel analyser measuring cloud point (ASTM D5773), pour point (ASTM D5949), kinematic viscosity (ASTM D7945) and density (ASTM D4052). European Lab Services (ELS)is pleased to announce to be fully capable of performing verification for this instrument according to ISO 17025.


This verification boosts the productivity of an analyser: the result accuracy and traceability is guaranteed, any discussion concerning the results is eliminated and the proactive verification approach will reduce risk of downtime. Every step of the test procedure in the analyser is checked thoroughly compared to its test method.


The accreditation of ELS also extends to all other petroleum physical properties, cold properties, density and viscosity analysers in the market.


European Lab Services is the only company worldwide performing on-site ISO 17025 accredited verification for petroleum analysers for petroleum testing.

The unique ISO 17025 verification concept of ELS is now applicable on


general lab equipment European Lab Services (ELS) was the first and still is the only company worldwide performing on-site ISO 17025 accredited verification of petroleum analyzers. Common examples are ASTM D93 Flash point testers, ASTM D86 atmospheric distillation and ASTM D445 kinematic viscometers. The goal of this performance evaluation is to guarantee the accuracy and traceability of the test results produced by the lab analyzers.

With an extension of the ELS flexible scope, European Lab Services is now capable of and allowed to perform verification of general lab equipment under the ISO 17025 accreditation. Next to petroleum equipment, the accreditation now also covers thermostatic regulators, water baths, calibration baths, centrifuges, fridges, ovens, climate chambers and many others. Combined with the ISO 17025 accreditation for calibration of temperature sensors and balances, European Lab Services is now capable of testing virtually all lab equipment for performance evaluation.

On-site customised Gas Standard Preparation has never been easier than with Zephyr – a compact version of well-known GasMix™ family from Alytech, France. This low cost, compact device is a smart companion in quality assurance for all gas analysers, GC or gas detectors helping you significantly reduce your stock of gas standard cylinders and related cost.


With its touch screen and intuitive interface, very simple in operation, Zephyr is widely used in various applications for gas mixing/dilution. It can create calibration gas standards from a concentrated gas and a diluent with a dilution ratio up to 10000; be employed for generation of synthetic atmosphere for an oxidation reactor or a glove box; make sample steam dilution and/ or internal standard addition.


GasMix™ is compliant with International standards method ISO6145-7 Gas Volumetric Preparation.


The dedicated Software ZeSoft is fully automated the operation and allows a single injection run or a fully automated and pre- programmed sequences that can be stored in the memory and recalled at any time.


Unique Smart Sequence building feature helps operator


to make multi-point calibration curves easily. User chooses the number of points, starting and ending concentration values, and the software calculates the respective concentration levels.


When it is used for the calibration of an analyser, accuracy of final concentration is very important. With Zephyr uncertainty of the final gas concentration is calculated automatically taking into account the used flow and the certified uncertainty of the parent gas.


Zephyr is compatible with aggressive gases and active compounds like sulfurs, H2


S, ammonia,


VOC. With its small foot print, imbedded smart software and internal battery (up to 8h autonomy operation) it can be installed where you need it, in the lab, in the field, in mobile lab.
