Epsilon 4 Oils & fuels

Save thousands in oil and fuel production

Epsilon 4 can be used to save up to $190,000 in the production of oils and fuels. Compliant, repeatable and accurate elemental analysis is a given but additional value is generated in several parts in your refining operation:

• the elemental analysis of crude oil to optimize and adapt refinery processes
• the determination of low levels of chlorine for optimal desalting and corrosion control
• the determination of low levels of S, Ni, V, Ca and Fe to prolong your catalysts' life and improve their performance
• and the analysis of the sulfur content during fuel production and blending

Analyses performed by Epsilon 4 comply with international test methods and regulations, like TIER 3, ISO 13032, ISO 20847, ISO 8754, ASTM D4294, ASTM D4929, JIS K2541-4, IP 336 and IP 496.

Epsilon 4 Lubricating oils

Value beyond compliance

Speeding up engine test while maintaining product quality are essential industry requirement for producers of lubricating oils. Compliance to international test methods like ISO and ASTM is an essential industry requirement for elemental analysis of lubricating oils. For the Epsilon 4 this mandated compliancy is merely the starting point, but where the instrument really shines is the additional value it brings for many other analytical tasks in the production of lubricating oils. For example:

• reduce errors of production by positive material identification
• faster and more accurate dosage of expensive additives
• supporting optimal blending efficiency of base oils and additives.

All analyses performed by Epsilon 4 comply with the latest test methods and norms, like ASTM D7751 and ASTM D6481.

Overview

Epsilon 4 Anywhere

Due to its low infrastructural requirements, Epsilon 4 can be placed next to the production line anywhere in your process. Its high performance enables most applications to be operated at ambient conditions, reducing costs for helium or vacuum maintenance. 

Value beyond analysis

Energy dispersive X-ray fluorescence spectrometer for the elemental analysis range from carbon (C) to americium (Am) and the concentration range from sub-ppm to 100 wt%.

Use Omnian for standardless analysis, use FingerPrint for material testing when analysis speed is important or use Stratos for a rapid, simple and non-destructive analysis of coatings, surface layers and multi-layered structures. One could also use Enhanced Data Security which supports compliancy with regulations like FDA 21 CFR Part 11 or use Oil-Trace for quantifying fuel-biofuel mixtures to fresh and used lubricating oils.

Ready for any sample type

The Epsilon 4 handles a wide variety of sample types, including solids, pressed and loose powders, liquids and filters. It performs non-destructive quantitative analysis of elements from carbon (C) fluorine to americium (Am), in concentrations from 100% down to sub-ppm levels, on samples weighing anything from a few milligrams to kilograms.

The Epsilon 4 is a robust and reliable alternative to conventional systems for a wide variety of industries and applications, even when light element analysis is of outmost importance, including: cement production, mining, mineral beneficiation, iron, steel and non-ferrous metals, RoHS screening and quantification, petroleum and petrochemicals, polymers and related industries, glass production, forensics, pharmaceuticals, healthcare products, environmental, food and cosmetics.

Features 

Flexible configurations

Epsilon 4 is a highly flexible analytical tool available in a 10-Watt version for elemental analysis (F – Am) in areas from R&D through to process control. For even higher sample throughput or extended light-element capabilities and in more challenging environments a 15-Watt version is available, which can even analyze carbon, nitrogen and oxygen.

Latest developments

Epsilon 4 instruments combine the latest excitation and detection technologies with state-of-the-art analysis software. The 15-Watt X-ray tube in combination with the high current (3 mA), latest silicon drift detector SDD30 together with the compact design of the optical path, deliver even better analytical performance than 50-Watt power EDXRF and even benchtop WDXRF systems - with the added bonus of power efficiency. 

Fast and sensitive

Fast measurements are achieved by using the latest silicon drift detector technology that produces significantly higher intensities.

Unique detector electronics enable a linear count rate capacity to over 1,500,000 cps (at 50% dead time) and a count rate independent resolution typically better than 135 eV for better separation of analytical lines in the spectrum. This allows the Epsilon 4 spectrometer to run at full power and therefore realizes a much higher sample throughput compared to traditional EDXRF benchtop instruments.

Reduce helium consumption

The high performance of Epsilon 4 enables many applications to be operated in air atmosphere, without longer overhead time and costs involved for helium or maintenance of vacuum system. When measuring in air, low-energy X-ray photons characteristic of sodium, magnesium and aluminium, are sensitive to variations in air pressure and temperature. Built-in temperature and air-pressure sensors compensate for these environmental variations, ensuring excellent results whatever the weather.

Enhanced data security

The Enhanced Data Security option for the Epsilon system software helps you strengthen your audit trail, minimize the risk of error, and prove that your XRF instrument is working as expected. Capabilities include advanced user management, action logging and data protection.
