Analytical Instrumentation 29 ERAFLASH - Te Safe Side of Flashpoint Testing
The patented PBT - Peltier Boost Technology™ by eralytics™ (Austria) opens a new dimension of flashpoint testing. Unrivaled measuring speed complements the widest temperature range ever achieved in a single instrument (-25 to 420°C). The small sample size (1-2 ml) and the continuously closed measuring chamber (ASTM D6450 & D7094) of the ERAFLASH™ guarantee maximum safety and speed at minimum costs.
ERAFLASH is the most flexible flashpoint tester for reliable measurements of all kinds of liquids and solids today on the market. A small footprint, true portability and its rugged aluminum design are ideal for stationary and mobile laboratories.
ERAFLASH also is the instrument of choice for demanding tests, including but not limited to fresh and used oil analysis (fuel dilution curve measurement), product specifications, transport classifications (D.O.T., ADR), forensic analysis, FAME (biodiesel), recycled fuels, hazardous waste (RCRA), etc.
The cost savings for expensive samples and for waste disposal as well as the easy cleaning due to the small sample volume make the ERAFLASH also the preferred flashpoint tester for the flavors & fragrances, the paints & varnishes and the bitumen industries.
The display of the Combustion Graphics™ on the large color touch screen is ideal for R&D applications and for the contamination analysis of demanding samples that contain only small amounts of flammable compounds (e.g. FAME / biodiesel).
To meet the strict safety requirements in today’s high-tech laboratories, ERAFLASH operates in full compliance with the safest Continuously Closed Cup Flash Point (CCCFP) methods ASTM D6450 and D7094. There are no open flames or glowing wires at all in the ERAFLASH. Instead, the flashpoint is detected by pressure measurement inside the closed measuring chamber. Naturally, this design completely prevents the risk of fire or hazardous fumes.
ERAFLASH additionally offers several correlation methods, which cover all major closed cup methods (e.g. ASTM D56 - TAG, ASTM D93 & EN ISO 2719 - Pensky Martens), as well as flash/no flash methods (e.g. EN ISO 3679 & 3680, ASTM D3828 – Small Scale). The correlation methods were developed by eralytics’ internationally renowned flashpoint specialists, Mr. Andreas Schwarzmann and Dr. Roland Aschauer.
The patented PBT - Peltier Boost Technology™, allows for previously unmatched heating and cooling rates. The Peltier elements are arranged above the measuring chamber following a revolutionary concept developed by eralytics R&D team. This new design allows turnaround times that are significantly shorter than those offered by all other instruments available on the market and enables measurements over the full temperature range of -25 to 420°C (-13 to 788°F) with a single analyzer.
Cleaning after measurements often took time and involved maintenance activities or replacing sensors or other elements of the chamber assembly. ERAFLASH is different. Its innovative CPT-Contamination Prevention Technology™, a combination of an advanced electrode protection and self- cleaning ignition system, reduces cleaning & maintenance to an absolute minimum.

Lubricating oils are given specific functional properties by mixing additives with base oil. In order to ensure consistent and desirable performance, the concentrations of the additives during the lubricant manufacturing process must be precisely controlled.
Sulphur compounds in petroleum can produce harmful effects such as air pollution, metal corrosion and catalyst degradation. Sulphur concentration of crude oil and high-sulphur fuels is monitored or controlled in refinery and production processes in the petroleum industry.
X-ray fluorescence (XRF) spectrometry has become increasingly popular for quantitative elemental analysis of base oils as well as additives and lubricant products thanks to its high precision and simple sample preparation.
Unlike many traditional techniques, XRF does not require chemical decomposition, digestion or serial dilution.
ASTM D6443-04 specifies the use of the wavelength-dispersive (WD) XRF technique because it offers sufficiently high precision, resolution and light- element sensitivity to meet the industry’s needs. Traditionally, WDXRF spectrometers have been large, floor-standing models with substantial installation conditions and high cost of component replacement. In its search for greater cost-efficiency however, the lubricant industry is turning to tools that not only do the job, but are also easier and less expensive to acquire, install and maintain
Lubricating oils and additives can now be routinely analysed with excellent accuracy, sensitivity and repeatability using the Rigaku (USA) Supermini200 benchtop WDXRF spectrometer with minimal site requirements.
Mercury in the Petrochemical Industry
PS Analytical (UK), have been involved in the determination of Mercury (Hg) since its inception in 1983 and has been heavily involved in the oil & gas industry for over 25 years.
They are ISO 9001 manufacturer of analytical instrumentation and sampling apparatus for trace metal analysis. One of our specialist areas is the determination of Hg in natural Gas, liquefied gas streams, naphtha, produced water, condensates and crude oil. PS Analytical have worked closely with all the oil and gas majors, the majority of the field testing companies and many of the mercury removal system suppliers. The Sir Galahad instrumentation complies with the latest ISO and ASTM methods for mercury in natural gas; ISO 6978:2 and ASTM 6350. They have also sold many online Hg systems worldwide.
In addition to this PS Analytical offer a consultancy measurement service and have undertaken numerous projects to validate the performance of mercury removal systems and establish the fate and transportation of Mercury for upstream and downstream operations.
