In addition, a new instrument discovery dialog makes it easy for users to find all the instruments connected to the software. IRIS is fully compatible with the latest revisions of MS Windows®.

“IRIS Software was designed to meet our client’s needs for increasing lab efficiency by providing the same software to manage numerous instruments, “said Eef Klok, PAC Vice-President of Product Management and Marketing. "To help our customers maximize efficiency, we have been continuously adding new plugins to IRIS. We currently offer 15 of the most frequently utilized PAC lab instruments, including the Herzog OptiDist, ISL PMD 110, AC Analytical Controls® Reformulyzer® M4, and ISL VIDA."

October

ISL PMD 110 is now approved for use in the ASTM Reference Standard D1655 for Aviation Fuels. ASTM recently added ASTM D7345, the PMD Method, to the jet fuel reference standard, D1655 as an alternative to ASTM D86. ASTM D7345 is the “Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure (Micro Distillation Method)”.

Based on an innovative micro-distillation method, the PMD 110 determines the boiling range characteristics of any commercially available petroleum product, including light and middle distillates, in less than 10 minutes and using only 10 ml of sample. Thanks to its compact, robust, and portable design, the PMD 110 is easily installed in mobile or on-site laboratories.

The PMD 110 is in perfect correlation with ASTM D86 (groups 0-4), ISO 3405 (groups 0-4), IP 123, and D1160 (for Biodiesel B100). With its automated features, such as built-in calibration, automatic sample detection, and an automatic pass/fail notification makes the PMD 110 one of the easiest distillation instruments on the market.

PAC has over 50 years of experience in developing automatic flash point analyzers for petroleum products, biodiesels, solvents, fluxed bitumen, food, and beverages. This newest edition is enhanced by being simpler to use, easier to clean, and safer to operate. The OptiFlash detects flash points up to 400°C and complies to leading global standards, such as ASTM D93, ISO 2719, EN ISO 2719, IP 34, JIS K2265, and GB/T 261.

With the OptiFlash’s intuitive user interface and built-in automation, users can now easily start a test without having to spend time doing manual tasks like installing the flash point and temperature sensors, as well as installing the test cup for each test. Its innovative design also makes it much easier to clean allowing the user to not only disassemble the cup cover without any tools but also to clean highly viscous samples, like bitumen. This improves the reliability of the test results significantly since customers can now run a quick clean before running any new sample.

“Determining the flash point of a product can be a dangerous test to run just due to its nature. With this in mind, PAC made sure to instill the highest safety standards into the new OptiFlash. With its ultra fast optical flame detector, the OptiFlash is the only instrument that can now detect a fire or even small flames in an extended range around the test cup,” says Eric Schellenberger, PAC President.

This new instrument replaces the previously released PAC flash point instruments, the Herzog HFP 339, Herzog HFP 360, and ISL FP93 5G2.

August

ISL Houillon Viscometers, the VH1 and VH2, comply with the recently released revised version of ASTM D7279-14 Standard, “Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids by Automated Houillon Viscometer”.

The new revision of the standard extends the scope from lubricating oils to include distillates (e.g., base oils, formulated oils, fuels, and biodiesel) and also adds a new precision at 40°C and 100°C, established through an interlaboratory study.

Our customers can now run their distillate oil samples on the VH1 and VH2 while complying with ASTM D7279. Requiring less than 1 ml of sample, the Houillon approach is applicable to both transparent and opaque samples, while needing less manpower to run. Since the kinematic viscosity results are produced within 60 seconds, the ASTM D7279 method has proven to be ideal for rapid testing of in-service engine oil conditions.

In addition to small sample size and fast analysis, the ISL Houillon Viscometers are easy to operate, flexible due to the capability to accommodate one or two solvents for cleaning, and robust in construction. Finally, the single-bath design, including 4 Houillon tubes, combined together with advanced automatic features, enable the simultaneous run of up to 16 tests.

June

The 393 sensor’s new design is configurable to the end user’s needs; it has numerous industry standard process connection options, including ANSI, DIN, and RTJ flanges. With these new connections, it is easy to install CVI’s patented sensor technology in petrochemical plants and refineries, including hazardous areas.

CVI’s technology is based on the oscillating piston method, which has only one moving part with no mechanical linkages. The sensor electromagnetically drives a piston through a fluid in a controlled measurement chamber at a constant force. Proprietary circuitry analyzes the pistons two-way travel time to measure the absolute viscosity. The sensor is constructed of all 316L stainless steel and the piston is constantly mixing the sample and scrubbing the measurement chamber clean.

Cetane Ignition Delay

PAC developed the newly released ASTM D7668 “Standard Test Method for Determination of Derived Cetane Number (DCN) of Diesel Fuel Oils—Ignition Delay and Combustion Delay Using a Constant Volume Combustion Chamber Method” for the PAC Herzog CID 510. It provides highly accurate Derived Cetane Number (DCN) analysis for diesel fuels with excellent correlation to the CFR Engine.

As part of the method development process, ASTM and the Energy Institute conducted an extensive interlaboratoy study in March of 2013. In the ILS, 17 laboratories participated from the United States and Europe to compare the cetane number determined with the referee method, ASTM D613 (CFR Engine Technology) and the derived cetane number determined with the ASTM D7668 (CID 510). The precision of the CID 510 (ASTM D7668) from the ILS study is much better than traditional CFR Engine technology (ASTM D613), as well as other CVCC instruments (ASTM D7170 and ASTM D6890). In addition to high precision, the CID 510 provides excellent correlation to the mean value of the CFR Engine.

“With other technologies, refineries had to compensate for less precise centane number results in Diesel by adding more cetane improver to the process just to make sure they do not go below the minimum specification requirement for cetane number ” says David Tran, PAC Vice-President for Product Management and Marketing. “ With the excellent precision and correlation of our CID 510 technology, refineries are able to run their process closer to the true specification limit for the cetane number of diesel, allowing them to add just the right amount of Cetane improvers and achieve significant cost savings. For a refinery producing 100,000 barrels of Diesel per day, operating at 1 cetane number closer to the specification could save as much as $800,000 USD per year.”

In addition to high precision, the CID 510 has significant benefits. It is easy to use with fully automated measurement and one push button operation, as well as automated calibration. It also contains enhanced safety features, such as a built-in fire monitoring and suppression system, over pressure protection for the fuel injection system and combustion chamber, and a fuel level sensor for the injection system. The CID 510 is a benchtop unit, which means it is much smaller than the traditional CFR engine technology that typically required its own room.

PAC pioneered the IP 599 method, “Determination of Fatty Acid Methyl Esters (FAME) in aviation turbine fuel - Gas Chromatography using heart-cut and refocusing”, that was recently approved and published by the Energy Institute (EI). As part of the approval process, EI conducted an in-depth interlaboratory study that included 8 laboratories from Europe and Canada analyzing the samples via this method. The precision, as calculated by the Energy Institute, exceeds the known statements for competing technologies such as IP 583 (IR), IP 585 (GC-MS) and IP 590 (HPLC) methods.

PAC developed this new method after its AC FAME in AVTUR analyzer, a unique gas chromatography analyzer combining deans-switching and re-focusing. It provides accurate quantitative data on individual and Total FAME components in the range of C16 to C18 with the option to analyze C14 FAME which is a marker for the presence of lower chain methyl esters such as those produced from coconut oil. This innovative method is specified for the range of approximately 3.5 to 116 mg /kg FAME; this is sufficient to meet the 5 mg/kg lower limit defined in DEF STAN 91-91 and ASTM D1655.

“In addition to higher precision and analyzing a wide range of jet fuels, this new method utilized by the AC FAME in AVTUR instrument is the easiest one to perform due to no sample preparation or complex multi component calibrations,” says David Tran, Vice-President of PAC Product Management and Marketing. “Due to its ease of use, a highly educated chemist is no longer required to run this analysis. It can now be used for routine analysis by refineries, distribution and pipeline companies, independent labs, airline companies, or military for the measurement of FAME (biodiesel) in jet fuel.”

April

PAC’s AC Analytical Controls Reformulyzer M4 fully complies with the recently released revision of the multi-dimensional GC method EN ISO 22854 method, “Liquid petroleum products — Determination of hydrocarbon types and oxygenates in automotive-motor gasoline and in ethanol (E85) automotive fuel -- Multidimensional gas chromatography method”, from CEN and ISO.

The main changes in this new method from the previous version are the addition of nitrogen as alternative carrier gas to helium, an update of the response factors for ethanol and ETBE, and an inclusion of a 2nd procedure that enables operators to analyze high ethanol fuels (E85) by using a dilution step. This allows the reporting of ethanol, ethers, and higher alcohols in fuels containing between 50% and 85% ethanol as this may be requested in future E85 specifications. The method is fully harmonized with the latest version of ASTM D6839, which was published in 2013.

PAC released the Reformulyzer M4, which determines full group type analysis of gasoline and gasoline blend streams using multi-dimensional gas chromatography, in September of last year. It is the fastest and most flexible analyzer on the market to combine analysis for Paraffins, Olefins, Naphthenes, Oxygenates, and Aromatics in one instrument.

“With the latest release of this method, the Reformulyzer M4 ensures our client’s compliance while also offering unique benefits. The M4 significantly reduces the total cost of ownership and increases the instrument uptime through the improved trap performance,” says David Tran, PAC Vice-President of Product Management and Marketing. “In addition, the M4 reduces analysis time by ~50% to 39 minutes while other group type analysis instruments take 75 minutes to run. This enables refineries to make timely decisions to keep their products on spec and optimize their operations. This same advantage allows independent labs to improve their capacity by almost doubling the number of samples they can process.”
