Analytical Instrumentation 17 New Age in Flashpoint Testing
MINIFLASH TOUCH is the latest addition to the AMETEK Grabner Instruments (Austria) line of portable flashpoint testers that combines all of the field-proven advantages of the MINIFLASH tester line with a new full colour touch screen design. The MINIFLASH series is a uniquely designed group of flash-point testers that uses a continuously closed cup method to determine the flash point of petroleum products, liquids and solids.
The MINIFLASH method offers the highest repeatability and reproducibility, an excellent and ASTM-proven correlation) to the D93 Pensky-Martens method. It delivers results equivalent to other well- known, closed-cup standards. Typical applications include the fast screening of diesel and jet fuels; the flash-point testing of potentially flammable goods, pharmaceuticals, aroma products, paints, varnishes, engine and lubricating oils; and the determination of solid waste composition and unknown mixtures of liquid hydrocarbons. The unit’s compact size and rugged housing make it the perfect solution for military applications, mobile labs and other demanding applications.
The MINIFLASH TOUCH utilises Ignition Protection Technology for maximum safety during flashpoint tests. This Grabner-developed method measures the instantaneous pressure increase inside a continuously closed test chamber resulting from an electric arc that ignites vapour from a 1 or 2 mL sample. No open flame is produced. Automatic explosion probing and automatic interruption of oxygen supply after flashpoint detection make the MINIFLASH the safest flashpoint tester available. The instrument’s innovative design also eliminates offensive fumes in the testing area and reduces sample waste.
For a quick sample turnaround and extended instrument life, Grabner Instruments developed Peltier Protection Technology, an advanced and fast thermoelectric heating and cooling regulation technology that extends the measuring temperature to well above 400°C and optimises performance and lifetime of the Peltier cooling.
Grabner Instruments has also developed Combustion Analysis to visualise the presence of contaminants and small concentrations of flammable compounds in samples. This gives users the opportunity to follow every millisecond of the flash combustion in unprecedented detail and makes the MINIFLASH suitable for flash-point testing of contaminated samples, biodiesel fuels and other difficult applications.

Analysis of Benzene, Toluene and Heavy Aromatics in Solvents
The BTX analyser is part of the Baggi (Italy) BASE Instruments Series.
It is the result of combining the latest state- of-the-art-technology with over 60 years of industry experience.
This real time process analyser is ideal for the measurement of the presence of aromatics (in parts per million) within hydrocarbon solvents. It uses
ultraviolet/visible spectrophotometry for achieving very accurate results.
The fully automated instrument is accompanied with a sampling loop, tailored according to the customer’s requirements. An ATEX version is available for operation in potentially explosive atmospheres.

PPB Arsine in Olefins Calibration Standards
Kin-Tek (USA) Trace Source FPK Gas Permeation Tubes are used with FlexStream or Span Pac I Gas Standards Generators to dynamically generate ppb calibration standards of arsine in a matrix of nitrogen, air, or polymerisation grade ethylene or propylene. Concentrations from below 10ppb to over 500ppb can be produced.
FPK Gas Permeation Tubes emit a small, steady flow of arsine vapour that is set by the temperature of the tube. That flow is mixed in the standards generator with a controlled flow of clean matrix gas to form the calibration gas mixture. Mixture concentration is adjusted by changing the matrix gas flow rate. Calibration based on the Standard Additions Principle compensates for unknown residual arsine in the matrix gas.
Trace concentration mixtures of arsine are generally not stable and must be dynamically generated. To minimise the hazard of working with arsine, FPK tubes contain only vapour phase at low pressure. Conventional tubes contain the condensed liquid analyte. FPK tubes can be totally sealed for storage and
shipping so that there is no fugitive emission of arsine. Reader Reply Card No 62 Reader Reply Card No 63 Annual Buyers’ Guide 2013 •
