Analysing Methanol, MEG, or THPS Across Diverse Samples

Updated: May 1

OMMICA is a robust method for analysing methanol, MEG, or THPS within a wide range of sample matrices. However, as most test samples are not pure, but may contain a cocktail of other process chemicals, a key question emerges:

How does OMMICA address potential interference from the diverse array of chemicals used in the crude oil production process?

Surprisingly, OMMICA minimises such concerns more than one might anticipate. A distinctive advantage of OMMICA assays lies in their species-specific nature. These assays exclusively target the substances under scrutiny, ensuring a focused analysis.

You use it? We (probably) tested it! 

OMMICA assays underwent comprehensive testing during their rigorous development. This testing covered the effects of primary classes of oilfield chemicals, including:

  • Asphaltene inhibitors

  • Biocides

  • Corrosion inhibitors

  • Defoamers

  • Demulsifiers

  • Enhanced oil recovery chemical cocktails

  • Foamers

  • H2S scavengers

  • Kinetic hydrate inhibitors

  • Oxygen scavengers

  • Scale inhibitors

  • Wax treatment chemicals


In the rare instances where potential issues surfaced, we subjected the concerned chemical classes to exhaustive OMMICA testing. Consequently, we can provide you with precise information regarding the concentration at which an issue may arise, typically surpassing the levels used in field applications.

If you find yourself with concerns about a particular process chemical when using OMMICA products, rest assured that our extensive testing likely covers it. Simply contact us at for specific inquiries.

Salts aren't a problem either!

For aqueous samples, our testing scope extends to a broad range of species:

  • Sodium salts (chloride, bromide, nitrate, sulphate, carbonate, bicarb, acetate)

  • Iron salts (Fe 2+ and Fe 3+)

  • 2+ cation chlorides (Calcium, magnesium, strontium, barium)

  • Organic acids (Formic, oxalic, glycolic)


If the presence of solutes in your sample is a concern, our team has tested a wide array of concentrations, ready to address your queries. We can also work with you on wider areas, for example if you have a complex model system that you wish to test.

When analysing the complex mixtures found in the offshore environment, OMMICA tests are not impacted by the presence of potential interfering species, ensuring your analyses remain reliable and accurate.
