MINIDIS ADXpert

Automatic and fast mini-distillation

This true atmospheric distillation analyzer is extremely compact, portable and light weight and operates as a fully stand-alone unit. Designed for the quick and accurate quality control in laboratories and in the field, a distillation run on light products takes just 15 minutes and requires as little as 6 mL of sample. Because of its small size the portable mini-distillation apparatus is the ultimate solution for places where limited or no lab-space is available.

MINIDIS ADXpert uses full automation from sample introduction to heating regulation, vapor temperature registration, volume measurement in the receiver compartment and calculation of the distillation curve from the raw data obtained during the test. This way it achieves the highest levels of accuracy, repeatability and reproducibility. The automatic operation involves simply inserting the filling tube into the sample container and pressing "RUN". No sample preparation like cooling is necessary, neither special programming of the test conditions or prior distillation knowledge is required. Fully automatic cleaning programs and the use of cheap and disposable sample cups guarantee highest productivity and eliminate the need to do manual cleaning of glassware.

MINIDIS ADXpert performs according to ASTM D 7344, the New Mini-method for the Distillation of Petroleum Products at Atmospheric Pressure and generates detailed D86 test reports. The distillation apparatus has a resolution about twice as good as D86 distillation units, yielding results that are well within ASTM D86 r/R requirements. The extremely versatile unit allows precise testing of various gasoline, jet fuel and diesel products (groups 0-4), biofuels, solvents, aromatics, organic liquids, chemicals and contaminated or blended samples.

Revolutionizing ASTM D 86 Testing

The automatic distillation analyser MINIDIS ADXpert is revolutionizing ASTM D 86 testing. It is a true atmospheric distillation analyser in an extremely small format. The automation significantly improves the repeatability and the reproducibility of the highly precise results. The MINIDIS offers a detailed ASTM D 86 compliant report and prints and/or transmits the results via a serial PC link.

Outstanding: Highest Safety

Broken glassware is one of the major reasons for fire hazards experienced when distilling with glass flasks. Because of the rugged metal housing, the sealed metal distillation cycle and the small sample volume the MINIDIS ADXpert does not need a fire protection system. Cheap and durable metal sample cups instead of expensive glass flasks significantly reduce consumable costs and make the MINIDIS ADXpert a perfect solution for distillation testing in challenging environments.

Full Automation for Highest Productivity

The MINIDIS ADXpert provides a complete distillation run and test report in 15 minutes (for gasoline) using only 6 mL of sample. The automatic operation involves simply placing the filling tube into the sample and pressing "RUN". No special programming of test conditions or prior distillation test knowledge is required. With the automatic sample introduction, the pre-programmed rinsing cycle and the use of disposable sample cups, any test preparation or manual cleaning of glass parts is avoided.

Unmatched versatility

Applicable for gasoline, jet fuel and diesel products (groups 0-4), biofuels, solvents, aromatics, organic liquids, chemicals and contaminated or blended samples. Fast measurements, automatic cleaning and close to no waste allow for versatile applications in laboratories, at-line or in Mobile Labs.

Problematic samples? No Problem!

Classical D86 distillation analyzers often encounter so called “problematic” samples. Mining solvents, condensates and raffinates for example cannot be measured by a D86 analyzer in most cases. MINIDIS ADXpert incorporates a versatile temperature control for a very small sample volume, which allows easy and fast heater adjustment. So even “problematic” samples can be distilled until the final boiling point is reached! The highly accurate volume detection system allows for precise and repeatable analysis of Biofuels and vegetable oils mixtures.

True Portability for All Applications

MINIDIS ADXpert performs according to the new D7344 standard for true atmospheric distillation. Results of the MINIDIS ADXpert excellently match D86, ISO 3405, IP123 and DIN51751 results. Fully automatic measurements, the temperature controlled sample introduction and a sophisticated automatic heating program eliminate sources for D86 distillation operator bias.

MINIDIS ADXpert features true portability, the rugged housing and optional 12V vehicle battery operation, making it the perfect solution for all kinds of applications, where standard laboratory instrumentation cannot be applied - like measurements in the field or in mobile laboratories.

Principle

The sample is introduced automatically into the disposable sample cup (2) and heated up with the electrical heating element (1) below. At the top of the distillation column (3) the temperature of the vapor is measured with a thermoelectric sensor (4). The volume of the condensate (7) is determined using a combination of an optical meniscus detection system (6) and a variable condenser chamber (5).

I am getting a position error message when trying to run a sample and the program crashes. Can anyone assist

MiniDis ADXpert

As a regulatory agency we need to use equipment that is ASTM approved. Is this unit ASTM approved for D7344? Can is run a approved distillation with product containing more than 10% ethanol?
