Results and Conclusion
The S8 TIGER with 4 kW excitation power and the curved germanium analyser crystal XS-GE-C easily achieves the analytical performance required for the determination of low sulphur in automotive fuels according to ISO 20884 and ASTM D 2622. It delivers impressive analytical precision allowing a close monitoring of the product quality. The requirements of ISO and ASTM are easily achieved. The results are shown in Table 6.
Therefore the S8 TIGER is perfectly suited for the sulphur test of automotive fuels in refineries, commercial testing labs and for governmental service labs in daily routine. Providing best analytical performance in combination with simple intuitive operation and failsafe handling of liquid sample the S8 TIGER provides peace of mind. The PETRO-QUANT solution package for ISO 20884 and ASTM D 2622 even provides the audit conform long term performance test, so even analytical quality audits are easy to pass.

Factory-Calibrated Fuel Blend IR Analysers Provide Measurement Data in Under a Minute
Factory-calibrated portable infrared analysers, available from Wilks Enterprise (USA), determine the percentage of ethanol in gasoline or biodiesel in under a minute to ensure correct fuel blends. Models are available for measuring various ethanol or biodiesel ranges from 0.2 – 100%. The InfraCal Blend Analysers are portable, rugged, compact and specifically designed for use by non-technical personnel. The user can take on-site measurements in under a minute at fuel terminals, service stations or do tanker spot checks and not have to wait days for off-site test results.
The InfraCal Blend Analysers are low-cost analysers that weigh less than 5 lbs. and can be operated from a battery pack or cigarette lighter adapter cable. They are self-
contained with an internal calibration program and direct readout display. The analysers can be supplied with a printer and include RS 232 interface that allows for data transmission to a PC. The InfraCal Blend Analysers are ideal for use in laboratories or in a rugged environment where a single, repetitive analysis is needed. They are currently being used by many major oil companies, regulatory agencies, fuel distributors and terminal operators. They provide the assurance that fuels blends meet specifications.

Thanks to the multi matrix sampler there is the security of being able to meet the most varied analytical challenges in next to no time with one single system – the multi EA 5000. Its intelligent construction facilitates the highest sample throughput ever in organic elemental analysis. Liquids and solids can be dosed. Horizontal sample feed via boats or vertical direct injection are two further functions for the same device.
The multi matrix sampler thus offers you four systems in one. No need for laborious conversion or adjustment: The active configuration is recognised fully automatically by the system itself.
Exceptional performance in design of process engineering systems and pilot plants for the petrochemical industry:
