PEFTEC 2017 - Show Preview Analysis of Gasoline using GC-VUV
At PEFTEC 2017 VUV Analytics Inc. will be showcasing how ASTM Method D8071 simplifi es the analysis of fi nished gasoline through the use of GC-VUV. The method provides complete PIONA compound class characterisation in a single measurement, potentially replacing the use of multiple legacy methods for this analysis. The setup procedure is easy and requires no pre-column tuning or valve timing adjustments. Faster GC run times can be achieved due to the method’s ability to handle co-elution among various species and hydrocarbon classes. The commercial application, known as VUV PIONA+, is suitable for use with fi nished gasoline, reformate, reformer feed, FCC, light naphtha, and heavy naphtha samples. Both methods will be on display in the VUV Analytics Inc. booth and discussed further by Dr. Kevin Schug and Dr. Thomas Groger during the fi nal afternoon session covering spectroscopic techniques and on-line analysis.

Fast Liquid FTIR Analysis The Specac Pearl
spectrometer accessory is drastically changing how liquid is analysed using FTIR transmission spectroscopy.
The liquid cell, aka ‘Oyster Cell’, is easily opened, changed and cleaned, allowing fast measurement of liquid sample of various consistencies with minimal preparation.
Samples can be introduced with a pipette or syringe and there is minimal mess or fuss.
Recently, Specac analysed Olive oil using the Pearl FTIR liquid accessory. A calibration curve was established, determining the % of sunfl ower oil against absorbance for future readings.

Automatic Distillation: Goodbye Dry Point Probe, Hello Optical DP Detection
The end point of a distillation test is typically determined by its fi nal boiling point. However, there are many samples such as pure products or other samples where the vapour temperature does not increase at the end. In these cases, the end point is determined by the moment when all liquid in the fl ask has vapourized, the so called Dry Point.
To measure the Dry Point, automatic distillation instruments need a DP sensor probe. Three of the main disadvantages of using a DP sensor probe are; fi rstly, insensitivity of the probe and the potential for imprecise positioning of the probe at the centre of the bottom of the sample fl ask can result in inaccurate detection and thus fl awed results. Secondly, DP probes break rather easily because they are fragile and diffi cult to handle and, fi nally; DP probes are expensive.

AirSTAR CPPP Innovation in Cloud & Pour Point testing
To overcome these problems, Orbis BV have developed Optical Dry Point detection, ODP. It detects the Dry Point without the need of an external probe. ODP is included in Orbis’ new PAMv2 Plus distillation unit as standard and at no extra cost. Applicable methods include ASTM D86, D1078, D850, E123 as well as other recognised industry methods such as IP195, DIN51751, ISO 3405.

Innovative Modular Design Improves Productivity and Flexibility for Cold Properties Testing
ORBIS BV have introduced a unique modular concept for Cold Filter Plugging Point, Cloud Point and Pour Point Testing.
Bram Hollander, International Sales Manager at Orbis BV, says “the AirSTAR range of CFPP and CPPP instruments were designed with fl exibility and lab effi ciency in mind”.
-105 ºC AirSTAR CFPP Head compatible

Both the AirSTAR CFPP and CPPP instruments use Orbis’ “ColdBlock” cooling unit (-105 °C/- 157 °F). The ColdBlock unit has been designed to automatically interact and operate with up to eight AirSTAR CFPP or CPPP instruments, which means users have the fl exibility to
switch AirSTAR testing Heads between different cooling units. Bram continues, “Each laboratory has its own test demands, the modular design offers lab workers fl exibility and increased productivity. For example, while one CFPP Head is automatically cleaned in the docking station another AirSTAR Instrument Head can use the ColdBlock cooling unit and start running the next CFPP/CP/PP test. The modularity of the AirSTAR design saves time and space.”
The AirSTAR instruments are easy to use, maintenance friendly and comply with traditional industry test methods. The AirSTAR range has been designed to improve effi ciency for those using the following cold property test methods; (CFPP) ASTM D6371, EN116, EN16329, IP309, (CP) ASTM D2500, ASTM D5771, IP219, IP444, ISO3015, JISK2269, (PP) ASTM D97, D6892, D5853, IP15, ISO 3016 and JISK2269.
