MPL Laboratories Extends NATA Accreditation to Amitrole, Chlormequat, Difenzoquat, Diquat, Mepiquat and Paraquat in Water by LC-MSMS

Envirolab Group is pleased to announce our Perth laboratory, MPL Laboratories, has further extended its scope of NATA Accreditation to include the analysis of Amitrole (a triazole herbicide), the familiar Diquat and Paraquat and the additional Quaternary Compounds Chlormequat, Difenzoquat and Mepiquat. These analytes are all accredited in water matrices to sub-ppb reporting limits using LC-MSMS.


Effective Tuesday, 9 February 2021, this group of compounds adds to an already extensive list of herbicides available on MPL Laboratories NATA scope. Further, this achievement enables our Perth laboratory to provide a more selective and sensitive analysis using LC-MSMS.


Our clients in the infrastructure sectors, including drinking water and sanitation, will benefit in areas relating to the analysis of pesticides, such as herbicide in water to near or below regulatory guidelines. “The now NATA accredited testing capability of identifying amitrole and the three additional QUATs, particularly Difenzoquat, which is on the Australian Drinking Water Guidelines (ADWG), will ensure greater confidence in reporting and therefore more informed decision making for our clients,” said David Williams the Group Organics Manager, based at our laboratory in Perth. 


The MPL LC team worked tirelessly during January to develop the analytical methodology and produce high-quality validation data required for gaining accreditation. The company extends a special thanks to Travis, Liz and Huong for your hard work and dedication.


Following a satisfactory technical review of the methods and associated data by NATA, the following have been added to MPL Laboratories’ scope of accreditation:


Amitrole; Chlormequat; Difenzoquat; Diquat; Mepiquot; Paraquat;


The detailed current scope of accreditation of MPL Laboratories can also be found in the NATA website directory



Significance of NATA Accreditation in laboratory testing services  

NATA Accreditation provides independent assurance of technical competence through a proven network of best practice industry experts. This accreditation is highly regarded as it formally recognises facilities across a range of industries that provide excellent standards of service in reliability, safety and efficiency in technical services.


The accreditation is granted to laboratories in compliance with ISO/IEC 17025 (2017) and the service-specific criteria, which is determined via an on-site assessment of resources, procedures, and documentation. As part of gaining accreditation, MPL Laboratories was required to demonstrate competency in performing all activities included within the concerned class or field of accreditation.
