Microbiology Laboratory

Eurofins-ELS operates a purpose-built 300m2 microbiological laboratory with spectacular views over the Wellington harbour. This laboratory features clean rooms, positive and negative pressure rooms, pathogen rooms, a large walk in chiller as well as a dedicated dairy sample processing room.

General Chemistry Laboratory

This section of our laboratory specialises in a large number of tests based on the chemistry methods published in volumes such as APHA and AOAC. We also offer tests of specialised matrices that are not accredited. This section is essentially the original ELS before we branched out into microbiological and instrumental techniques. Most laboratories in New Zealand have a general chemistry capability because most samples we analyse have the need for this type of test.

Examples of the tests performed include, pH, alkalinity, turbidity, TKN, COD, and other tests that we often refer to collectively as 'shorts'.

Instrumental Chemistry Laboratory

This section is comprised of many specialised instruments that together form the automated aspect of our work. This laboratory includes some of the most complex analytical techniques available to laboratories, and we are committed to growing on the equipment and staff skills available to us.

Instruments operated include:

  • ICP-MS

This technique for analysing metals is the best that is currently available. While very expensive, we are fortunate to own and operate two instruments. Both are capable of performing very low level determinations of metals such as Cadmium, Chromium, Arsenic, Lead and even Tungsten and Uranium.


This technique also analyses metals, and while considered a simpler technique is better at some elements than our ICP-MS's. The alkali metals such as calcium, potassium, and magnesium perform better on this instrument.

Because of our commitment to the integrity of our results, we run samples through both instruments to ensure the best result is reported.

  • Ion Chromatography

We operate two Ion Chromatographs for the determination of anions in water and air. Anions include fluoride, chloride, bromide, nitrate, and sulphate and are good water quality indicators. The instruments can also analyse oxyhalides such as bromate and chlorite.

  • Flow Injection and Discrete Autoanalysers

Nutrient analysis forms a large part of our business and we achieve this through the use of Flow Injection and Discrete Autoanalysers. These instruments perform nitrogen and phosphorus analyses and are also used to determine ammonia, cyanide, and hexavalent chromium. They take slow, manual colorimetric tests and automate them to speeds that are quite amazing. Samples are processed every few seconds allowing us to perform your analyses in duplicate – a more analytically robust technique than performing the test singly.

Organic Chemistry Laboratory

Our organic chemistry section operates GC-MS, GC-MS triple quad, GC-FID and LC-MSMS instruments.

Between them the instruments are capable of analysing a wide range of analytes:

  • Total Petroleum Hydrocarbons (TPH), BTEX,
  • Volatile Organic Compounds (VOC)
  • Semi-Volatile Organic Compounds (SVOC), pesticide and herbicide residues.

Biological Fluids Laboratory

The biofluid laboratory principally serves the Occupational Health industry for New Zealand. We analyse blood, serum and urine for a wide range of metals and fluoride to check workers health.

We operate this laboratory independently of the rest of the facility including a dedicated Laboratory Information Management System (LIMS). We choose to do this for privacy reasons.
