Analysis of Linear Alkylbenzene Sulfonic Acid and Its Salts (LAS)

We provide total support from container rental to analysis results!

Linear alkylbenzene sulfonic acid and its salts (LAS) are used as anionic surfactants in household laundry detergents and were newly added as environmental standards for the conservation of aquatic organisms in public water bodies on March 27, 2013. Due to the low concentration of the environmental standard set at 6-50 μg/L, the high-performance liquid chromatography-tandem mass spectrometry (LC/MS/MS) method was designated for measurement as the first measurement method for the environmental standard. MST provides a comprehensive service from the loan of specialized containers to measurement.

Analysis case: Analysis of Nonylphenol (NP)

We provide total support from container rental to analysis results!

It has been announced that nonylphenol (NP) will be newly added to the environmental standards concerning the conservation of aquatic organisms, as part of the environmental standards related to the preservation of living environments affected by water quality pollution (August 22, 2012). NP is considered a substance of concern due to its impact on living organisms, and the standard values are set between 0.0006 to 0.002 mg/L, depending on the water area and type. We will introduce a case study that evaluated NP concentrations within this concentration range. MST provides a comprehensive service that includes the lending of specialized containers and measurement.

[Analysis Case] Analysis of Lauryl Sulfates in Daily Necessities

You can check the content of lauryl sulfate in the product.

Sodium lauryl sulfate (and ammonium lauryl sulfate, etc.) is used as an emulsifier, foaming agent, and cleaning agent in everyday products, pharmaceuticals, and industrial goods. This document presents measurement examples of everyday products (toothpaste, shampoo) that list sodium lauryl sulfate as an ingredient and those that do not list lauryl sulfates. By measuring with LC/MS/MS, it is possible to investigate the content of lauryl sulfates in the products.
