All Eralytics analyzer results are displayed immediately after the test on their large and user-friendly color touch screen.Videos

Introducing the ERASPEC: High-Precision Fuel Analysis with FTIR Technology
The ERASPEC is a cutting-edge mid-FTIR spectrometer engineered to deliver fast, precise fuel analysis, crucial for maintaining fuel quality, ensuring regulatory compliance, and supporting advanced research. Leveraging its patented interferometer, the ERASPEC measures the complete infrared spectrum of various fuels, such as gasoline, diesel, and jet fuel, within less than 60 seconds. This device stands out due to its ability to automatically derive critical fuel properties, including Octane and Cetane numbers, distillation points, and the concentration of fuel components like ethanol and benzene, oxidation, aromatics, olefins and many more parameters, all from a minimal 10 ml sample.
Designed with versatility and ease of use in mind, the ERASPEC supports a range of analytical modules, making it adaptable for many standards. The device's fully automated operation requires no warm-up time, sample preparation, or manual calibration, ensuring quick and highly accurate results with minimal operator intervention. The robust, portable design of the ERASPEC, coupled with its intuitive touchscreen interface, makes it an ideal choice for both laboratory and field applications, even in challenging environments like oil platforms.
The ERASPEC’s comprehensive data management capabilities allow for seamless integration into existing workflows, with options for data storage in the equipment, USB transfer, RS232 interfaces, direct LIMS connectivity via LAN, and direct report printing. Its compact form factor 29 x 35 x 34 cm (11.4 x 13.8 x 13.4 in) and light weight 9.7 kg (21.4 lb) make it highly portable, ensuring that reliable fuel analysis is always at hand, whether in a fixed lab setting or out in the field. This device is essential for industries requiring high-precision fuel testing and is backed by a standard 1-year warranty, extendable to 2 years under manufacturer’s terms.
Applications of the ERASPEC Include:
Monitoring fuel quality in refining and blending operations
Compliance testing in fuel production and distribution
Highly accurate on-site fuel analysis in mobile and field settings
Supporting R&D in fuel composition and properties
