UOP744, Aromatics in hydrocarbons by Gas Chromatography

The UOP744 describes the method for individual determination of C6 through C10 aromatic compounds in petroleum distillates or aromatic concentrates having a final boiling point of 210°C or lower.

The advantage of UOP744 is that this method may be used to provide a distribution of C8 aromatics an/or C9 and heavier aromatics.
In addition, this method also describes an extension for these components which have a final boiling point less than 344°C (nC20). When these methods are used the limit of quantitation of a single aromatic component is 0.01 mass-%.


ASTM D6729, Determination of Individual components in spark ignition engine fuels by 100 metre capillary high resolution gas chromatography

Scion Instruments offers the solution for detailed hydrocarbon analysis (DHA). Spark ignition engine fuels consists out of hundreds of hydrocarbon compounds, with this method according to ASTM D6729 these components can be distinguished and analysed. The ASTM D6729 describes a standard test method for individual components in spark ignition engine fuels by high resolution gas chromatography.


Residual Solvents analysis of cannabinoid products by Headspace GC-MS

This application focusses on Residual Solvent analysis but SCION Instruments has an extended portfolio including potency analyses (AN091, 92, 93 and 130) and Terpene analysis (AN133 and 136).


ASTM D6730, Determination of Individual Components in Spark Ignition Engine Fuels

SCION Instruments offers the solution for detailed hydrocarbon analysis (DHA). Spark ignition engine fuels consists out of hundreds of hydrocarbon compounds, with this method according to ASTM D6730 these components can be distinguished and analysed.


Determination of Terpenes in Cannabis by Headspace GC-SQMS

Hemp and marijuana are becoming more popular because of legalisation in multiple countries. The increase of this market also increases the offer of products and therefore the need to monitor different components. This application focusses on terpenes analysis using GC-SQMS, for Terpene analysis using GC-FID see application note 133.


UOP690, C₈ and Low Boiling Paraffins and Naphthenes in Low-Olefin Hydrocarbons by GC.

The UOP690 describes the determination method for C8 and lower boiling paraffins and naphthenes in olefin free gasolines (2 mass-%) with a maximum boiling point of 260°C. In this method benzene and toluene are also being determined.


Simultaneous Analysis of Triazole Fungicides by HPLC-DAD

Triazole fungicides are chemical compounds that are not only used to kill parasitic fungi but also act as plant growth regulators when used properly. There has been an increase in local regulations surrounding the use of such chemical compounds due to their devastating effects on humans and the environment. SCION Instruments developed a method for the simultaneous analysis of two common triazole fungicides; Paclobutrazol and Uniconazole.


Determination of Terpenes in Cannabis by GC-FID

Hemp and marijuana are becoming more popular because of legalisation in multiple countries. The increase of this market also increases the offer of products and therefore the need to monitor different components. One of these components are cannabinoids or just short potency analysis, which can be found in our portfolio of Cannabis applications (AN091,92,93,130). This application focusses on analysis of Terpenes in Cannabis.


Characterization of Bath Salt Using HT3 Headspace Sampling

In this application note we discuss a static headspace method on the HT3 sampler for rapidly determining drug components for use in forensic applications. A HT3 headspace sampler will be used to examine bath salt samples for the presence of mephedrone and methylenedioxypyrovalerone.


Blood Alcohol Determination by Versa Headspace Sampling

In this application note we discuss the Versa sampler that was evaluated to determine its suitability to perform an occasional blood alcohol test. Methanol, acetone, ethanol, isopropanol and acetaldehyde along with n-propanol, a typical internal standard, were tested with the Versa sampler.
