ASTM D1160 Compliant Computer Controlled Boiling Analysis
Iludest are renowned chemical engineers who have built a reputation over decades of supplying custom-built semi-automatic and fully-automatic laboratory installations and pilot plants that meet the precise specifi cations of the petroleum industry. With over 300 installations worldwide, Iludest are unsurpassed at confi guring one-off assemblies which cater to individual specifi cations, e.g. purifying lub oils, essential oils, industrial blended oils, etc.
Aside from providing entire turnkey systems, Iludest have a range of their own tried and tested analytical tools that have been instrumental in their success. One of these is the i-Fischer®
DIST D-1160 CC / FISCHER® AUTODEST® 850 AC, a fully computer controlled
unit of turn-key design, and ready for use after installation and commissioning. The unit extends the current test method and does not limit your vacuum distillation testing options.
Users can defi ne their own tailored program above and beyond current standards. The system is fully housed and equipped with doors in the front and rear to satisfy safety requirements and to facilitate servicing the unit.
The protocol is printed out and shown on the monitor whilst distillation is being carried out featuring distillation curves in actual boiling temperatures (ACT) and atmospheric equivalent temperatures (AET) as well as essential distillation parameters. The fi nal data and the distillation curves are printed and stored on hard disk and/or data disks.

Cost Calculator Developed to Highlight Savings Achieved by Using New ASTM Method D8045
Metrohm is proud to announce the release of a new calculator that helps refi neries defi ne their cost savings when using a new method developed by the ASTM. Recently published method D8045 utilises thermometric titration for Acid Number (AN) determination in crude oil and petroleum products. Acid Number is an important quality parameter and is used to determine a refi ning value for crude oil. Compared to the traditional and well-known ASTM method D664, which utilises potentiometric titration for Acid Number determination in crude oil, laboratories that run D8045 save by lowering the amount of solvent required. A laboratory that runs just 25 crude oil samples per day will save an average of over $30,000 per year in solvent costs. The calculator is customisable by adjusting sample and solvent cost values for each laboratory and can be accessed by visiting the Metrohm website. In addition to these signifi cant cost savings, D8045 is also much faster than D664, completing the analysis in 1 minute as opposed to 3 minutes for D664. Sensor conditioning or maintenance are not required.

The VIDATM analyzers integrate innovative features to ensure reliable and accurate analysis of light and mid distillates, heavy oils, food and beverage applications or mobile labs.
VIDA is designed to be a true “push-button” solution, based on the proven oscillating U-tube method. Its smart software automates every step of the test sequence from sample injection, bubbles detection to system cleaning and data reporting allowing minimal operator attendance but also enhanced fl exibility. The automatic cleaning feature reduces maintenance time and consumption of solvents, even when testing diffi cult samples.
We offer integrated tables for automatic conversions of density output for: API crude oil, refi ned products & lubricants, as well as alcohols, acids, alkalis, sugars and customizable tables (VIDA80H).
Special functions guarantee a complete operation traceability together with extra quality assurance in data management and strict compliance with ASTM D4052, ASTM D5002, ASTM D5931, ISO 12185, ISO 15212-1, DIN 51757 and JIS K2249-1.
VIDA comes in several presentations for different applications:

Automate the Analysis of Active Oxygen with Fast Peroxide Analyser
Hydrocarbon streams such as Styrene, Isoprene and Butadiene may form thermally unstable peroxide types on exposure to air. Accurate monitoring of reactive peroxide traces is required to prevent hazardous plant conditions. The Fast Peroxide Analyser developed by Da Vinci Laboratory Solutions is an automated, fast and precise alternative to traditional wet chemistry methods such as ASTM D2340 and E299.
The DVLS Fast Peroxide Analyser (FPA) is based on an HPLC stack including a quaternary pump, an automated sample introduction system, an UV detector and instrument control processing software. The analysis of Peroxide, as active Oxygen, is based on the oxidation of Iodide by Peroxide. Two reagents, Acetic Acid in Propanol and Sodium Iodide in Propanol are mixed, resulting in a stream of acidifi ed Iodine solution in Propanol. The sample is injected into this stream.
3,000 sccm
Next step is to lead the liquid stream through a heated inert reaction coil. Iodine is formed under temperature controlled conditions inside the dedicated reaction oven developed by Da Vinci. After passing the reaction coil the HPLC UV detector spectrophotometrically determines the formed Iodine, which is proportional to the level of peroxide.
The reaction oven developed by Da Vinci enables an optimal heat distribution to the reaction coil. The oven design matches the HPLC modules thus allowing stacking of the oven between the autosampler and the detector.

The module contains two heating plates; one plate is situated directly above and the other one is located directly below the reaction coils. To stabilise the heating cycle and to prevent a temperature overshoot an air fan is installed at the back of the module.
The outlet of the reaction coil is placed in a cooling compartment to ensure a cooldown of the reagents and product before they enter the UV detector. The oven maximum temperature is 225°C (437 °F).
Linearity was determined by measuring the prepared concentration range of I2 in Propanol. Each concentration was measured in triplicate. The test results show that the linearity of the FPA is set at R2 ≥0.999 over a range of 3 – 100 mg/L I2 in Propanol, which is equivalent to 0.2 – 6.3 mg/L active oxygen.
The LOD for I2 is measured at 0.46 mg/L at a prepared I2 concentration of 13.8 mg/L and 1.23 at a prepared concentration of 55.2 mg/L. Comparing the measured LOD values with the target of ≤ 3 demonstrates the excellent performance of the Fast Peroxide Analyser.
