Gasoline Additive to Eliminate Uncertainty in Fuel Blends is Featured in New White Paper


A new White Paper published by Wilks Enterprise (USA) presents the advantages and cost savings for on-site analysis with a portable mid-infrared based analyser, such as the InfraCal Ethanol Blend Analyser, to help fuel blenders quickly flag out-of-spec product and ensure the final blend meets specifications. This analysis is important as the use of ethanol as a gasoline additive has increased dramatically over the past few years and will likely continue to increase.


For fuel blenders, this means an added challenge to avoid an incorrect blend that could lead to regulatory fines, loss of customer confidence and damage to equipment. Portable infrared analysers offer a simple, accurate and low cost solution to on-site blend testing at locations such as the blending rack. The resulting costs of an incorrect blend can far out way the modest cost of an on-site ethanol blend analyser. With many already in use at petroleum terminals and by regulatory agencies, the InfraCal Ethanol Blend Analyser has proven to be a reliable tool to ensure blend accuracy.

the new ADU 4+ automatic distillation tester with built-in cooling system, fire extinguisher and integrated computer with external flat screen monitor and ADUPro software. The compact, rugged unit performs distillation testing at atmospheric pressure of aviation fuels, gasoline, turbine fuels, fuel oils, kerosene, naphtha, solvents, special boiling point spirits and a wide


variety of petroleum products.Performing distillation testing manually, typically requires considerable operator experience to be done properly and safely.


Reading a thermometer, observing the receiver, manually adjusting the heating and recording test results must all be done accurately and simultaneously. With the Petrotest ADU 4+ all of these steps are done automatically using state-of-the-art electronics, avoiding incorrect ASTM D86 measurements and eliminating operator bias.


The modular ADU 4+ provides fully automatic analysis of boiling characteristics according to ASTM D86, D850 and D1078-IP 195. The unit also can be customised to perform user-specific applications. A powerful 1200-watt heater provides heating up to 450 0C (depending on sample and stem correction mode). All distillation criteria, e.g. cooling temperature and chamber tempering, can be switched over automatically from group 1 to 4 during the distillation. The unit includes glassware set according to ASTM D86 (Group 1-4). With additional accessories, the unit is suitable for testing of aromatic hydrocarbons and volatile organic liquids according to ASTM D850 and ASTM D1078.


The ADU 4+ is designed as a complete ready-to-go system that occupies only a minimum amount of laboratory bench space. The highly versatile unit features volume detection by solid-state light barrier system, rugged high-grade stainless steel powder coated cabinet, temperature-controlled swing-out receiver chamber and digital display with membrane keys.

New Compact Distillation Tester


Liquid Flow Sensor for Low-Volume Dosing Applications


Swiss sensor manufacturer Sensirion is launching a flow sensor for flow rates below 2 cc/sec (120 ml/min) with hydrocarbon-based liquids such as photoresists and solvents.


Designed for use in high-purity fluid handling applications in the semiconductor, PV and flat panel display industries, the new SLQ-QT105 sensor features a short measurement response time of approximately 40 ms and very high sensitivity for flow rates down to 0.05 cc/sec (3 ml/min). Detection of air bubbles in the microliter range is also possible.


Flow is measured without moving parts and non- invasively through the wall of a straight flow path. All wetted materials are made from Teflon®


or quartz glass.


The compact, lightweight device is equipped with fittings for 4x3mm PFA tubing. A smart digital interface and robust RS485 communication is offered for long distance and bus capability.


According to product manager Jonas Horn, the SLQ- QT105 opens new perspectives for high-purity process control by remedying the shortage of precise, reliable, fast and inexpensive sensors for flow rates in the low milliliter range.


Mechanical solutions, such as small paddlewheels and ultrasonic flow meters, are often unable to fulfill requirements due to their slow response, problems with bubbles, and inability to measure flow rates below 100 ml/min repeatably.


With the SLQ-QT105, the advantages of CMOSens® Technology are now available for the first time for use in high-end semiconductor applications.
