Why to test for carbon residue? When fabricating gasoline from gas oil it is essential to evaluate the build up of carbon residue. Carbon residue is formed by evaporation and thermal degradation of material containing carbon.
Petroleum products contain ash-forming components which decompose during distillation using atmospheric pressure techniques so understanding the carbon residue value of carbon deposits from unrefined petroleum remnant is important when producing valuable commercial oils and lubricants.
The test method ASTM D524 uses a Ramsbottom glass coking bulb when determining the amount of carbon residue within the test sample. The glass coking bulb is made of heat-resistant borosilicate glass and should be manufactured to dimensions that meet the ASTM standards. In this case the coking bulb needs a capillary tip with an opening that measures between 1.5 to 2mm to allow for the insertion of a rod with a diameter of 1.5mm.
Crystal Science USA Corporation has a team of staff with over 30 years’ experience in manufacturing glassware to ASTM specifications using borosilicate and quartz materials. These durable glass materials have clear cost advantages and during the lifetime of the product offer better accuracy of results than other glass materials.
Atilano Martinez, CEO of Crystal Science USA Corporation, says “we pride ourselves on customer service, in addition to providing high quality products. Crystal Science offer design and engineering services enabling us to provide the petroleum market with bespoke solutions for specific applications or special projects.”

ISO 6614 M E TH O D C O M P L I A NCE ASTM D1401
Following the success of the 20 years old first release software platform, SRA Instruments released the new Soprane II version of its chromatographic software exclusively dedicated to all MicroGC analysers.
“Developed together with MicroGC Users”, this is the main motif of the Company in all the years of development and improvement. A completely new architecture in a modern design, Soprane II incorporate all the features that a fast-analytical response equipment require today, especially showing and handling large amount of results from displaying to exporting.
The Software features also enlarge the applicability of the technology. The MicroGC is a compact and small analyser, often used for on-site analysis, software must be easy to use and accessible to all users in its basic functions, from run sequences to results. A simple click on the main analysis results screen can activate the chromatogram visualisation, batch reprocessing or calibration or signal comparison.
Several features for automation are available to handle several valve types, relay, external devices and using industrial protocols. Like the modbus, the MicroGC can be applied in process environment also using the proprietary ExProof version for continuous on-line gas monitoring.
A trial version is available on
www.srainstruments.com/soprane-II to test all the functionality of the new Soprane II.
