Analysis of Linear Alkylbenzene Sulfonate (LAS)

Analysis Analysis of Linear Alkylbenzene Sulfonate (LAS) and Its Salts

We perform LAS analysis in accordance with the Japanese Environmental Quality Standards for Water (Environmental Agency Notification No. 59 of 1971, Appendix 12). With many years of experience analyzing LAS in various water samples, including environmental water and wastewater, we maintain rigorous quality control through careful management of laboratory equipment and analytical procedures to ensure accurate and reliable results.

Overview

We provide analytical services for LAS in environmental water and wastewater.

LAS is a type of surfactant widely used in household detergents and cleaning products. Based on toxicity studies and environmental monitoring data indicating potential impacts on aquatic organisms, LAS was added in 2013 to Japan's Environmental Quality Standards for the Conservation of the Living Environment under the Basic Environment Law as an environmental standard for the protection of aquatic life.

Our analysis targets LAS compounds with alkyl chain lengths of C10 to C14. The concentrations of each carbon-chain component are individually determined and reported as the total LAS concentration.

Applications

Evaluate the treatment efficiency of your facility by analyzing water before and after wastewater treatment prior to environmental discharge.

Verify that wastewater is properly treated before being discharged into the environment.

Monitor changes in LAS concentrations in rivers, lakes, and other aquatic environments through routine environmental monitoring.

Survey and Analysis Process

We provide a complete one-stop service, from sample collection to the delivery of official analytical reports.

Step 1: Sample Collection

Our field technicians can collect samples on-site. We also accept customer-submitted samples. Please contact us for details.

Step 2: Pretreatment and Analysis

Analyses are conducted in accordance with the Japanese Environmental Quality Standards for Water (Environmental Agency Notification No. 59 of 1971, Appendix 12).

Analysis and Reporting Process
Process from Analysis to Reporting

Detection Limit: 0.0001 mg/L (Total LAS)

Step 3: Issuance of Test Report

An official analytical test report will be issued upon completion of the analysis.

Features

LAS is one of the most commonly used surfactants in everyday products and is therefore highly susceptible to contamination during analysis.

With extensive experience analyzing LAS in environmental water, wastewater, and other water samples, we maintain strict control of laboratory equipment and analytical procedures to ensure high analytical accuracy and reliable quality control.
