MPL Laboratories Gains NATA Accreditation For Additional Analytes using GC-MSMS Methods

Envirolab Group is pleased to announce our Perth laboratory, MPL Laboratories, has extended its scope of NATA accreditation to include additional haloacetic acids, some chlorophenols, dalapon and chloral hydrate in waters by gas chromatography–tandem mass spectrometry (GC-MSMS). Additionally, phenoxyacid herbicides in both waters and solid environmental matrices using GC-MSMS are also now NATA accredited. This accomplishment adds to MPL’s current accreditation of these important analytes using GC and GC-MS.


Effective Monday, 4 January 2021, this achievement enables MPL Laboratories to provide a more selective and sensitive analysis using the GC-MSMS. The benefits allow the analysis of a larger number of compounds in a single instrument cycle as well as lowering the potential for interferences on data. This assists our clients as we are able to offer lower detection limits and improved laboratory efficiency, whilst also reducing the amount of sample required for analysis.


Following a satisfactory technical review of the methods and associated data by NATA (National Association of Testing Authorities, Australia), the following have been added to MPL Laboratories’ scope of accreditation:


Phenoxy Acid Herbicides
(R)-2-(2,4-Dichlorophenoxy)propanoic acid (dichlorprop, 2,4-DP); 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T); 2,4,6-Trichlorophenoxyacetic acid (2,4,6-T); 2,4-Dichlorophenoxyacetic acid (2,4-D); 2,6-Dichlorophenoxyacetic acid (2,6-D); 2-(2,4,5-Trichlorophenoxy)propionic acid (2,4,5-TP, fenoprop, silvex); 2-Methyl-4-chlorophenoxyacetic acid (MCPA); 2-sec-Butyl-4,6-dinitrophenol ([RS]-2,4-dinitro-6-sec-butylphenol, dinoseb); 3,5-Dichlorobenzoic acid; 3,6-Dichloro-2-methoxybenzoic acid (dicamba); 4-(2,4-Dichlorophenoxy)butanoic acid (2,4-DB, [2,4-dichlorophenoxy]butyric acid); 4-(4-Chloro-2-methylphenoxy)butanoic acid (2,4-MCPB, MCPB, 4-[4-chloro-o-tolyloxyl]butyric acid); 4-Amino-3,5,6-trichloro-2-pyridinecarboxylic acid (picloram); 4-Chlorophenoxyacetic acid (4-CPA); Acifluorfen; Bentazone; Bromoxynil; Chloramben; Clopyralid; Dimethyl tetrachloroterephthalate (DCPA, dacthal); Fluroxypyr; Ioxynil; Methylchlorophenoxypropionic acid (RS-2-[4-chloro-2-methylphenoxy]propanoic acid, MCPP, mecoprop); Triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid);

Thanks to Group Organics Manager, David Williams and the Organics Team at MPL Laboratories for all the hard work and planning that went into the accreditation process.


MPL Laboratories looks forward to providing this service to existing and future clients.



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.
