ASTM D8148 takes haze and clarity ratings to the modern age

With modern engine systems, and the increasing use of synthetic and bio derived fuels, the importance of cleaner fuels becomes more critical than ever.  Choice Analytical, Inc.’s innovative Clarity Choice hz leaves inconsistency in the past and replaces it with spectroscopic accuracy, all within minutes.

“Hazy product is the number one quality issue we face as a pipeline company and Hazy product remains the biggest cause for pipeline transfer issues resulting in significant loss of revenue and productivity.” stated Magellan Midstream Partners’ Origin Product Quality Manager, Rod Lawrence.  To combat this major issue, the Clarity Choice hz uses a unique set of optics to achieve unparalleled precision in what was formally a decades old visual, highly subjective rating system and is the only instrument in the industry that performs the new ASTM Standard Test Method D8148.

The Clarity Choice hz enables the operator to carefully monitor the fuel clarity and haze by using specialised optics. This process provides the user with an Instrument Haze Rating (IHR) which correlates to the current ASTM D4176 Procedure 2 but with much greater precision.  More importantly, the Haze Clarity Index (HCI) found in D8148 provides the user with a true linear rating with significantly greater definition and precision. With the optional external solid-state temperature control module, products with temperatures below and above ambient can be tested to simulate conditions in the field.

HCI can be used to evaluate haze Intensity changes to a much finer degree than could ever be achieved with visual inspection procedures.  The Clarity Choice hz only needs 10mls of sample and delivers a measurement in just 105 seconds making this the ideal solution for rapid, precise and reliable haze and clarity determination measurement of transportation fuels.  Anyone who has experienced the costs of delays in custody transfer will appreciate the commercial value of this technology.
