The laboratories
Built to satisfy our own quality gates first.
Isondo has set up fully equipped, state-of-the-art analytical and MEA testing laboratories complying to ISO/IEC 17025, ISO 45001, ISO 14001 and ISO 9001 standards, to serve the company's own needs in analysing PGM content, PGM catalysts, catalyst precursors and MEA performance.
They sit alongside cleanroom production running to Class C / ISO 7 with localised Class B / ISO 6 zones — the controlled environment high-purity and electronic-grade materials require.
Because those laboratories were specified to clear our own production, they are equipped and staffed well beyond what a service-only laboratory would justify. We make that capacity available to customers, counterparties and third parties who need the same standard of answer.
What we can run for you
Eight services, available to third parties.
Our laboratories are able to service customer needs across the following areas. If your requirement is adjacent to this list, ask — the equipment base is broad.
Catalyst-coated membrane assays
Assays relating to catalyst-coated membranes, including particle size analysis.
Metal accounting assays
Assay work supporting metal balance and accounting across a process or a plant.
Umpire & third-party assays
Independent umpire assays where two parties to a transaction need a referee result they both accept.
Sampling & sample preparation
Representative sampling and preparation — the step where most assay disputes are actually created.
Internal auditing for stock take & compliance
Audit support for precious metal stock takes and compliance obligations.
Customised calibration standards
Preparation of customised laboratory calibration standards, as solid materials and as solutions.
MEA lifecycle & durability testing
Electrochemical performance characterisation, plus lifecycle and durability testing of membrane electrode assemblies.
Why bring work here
Three reasons counterparties choose an independent lab.
Accredited method, defensible result
Work is run under ISO/IEC 17025 laboratory management, inside a quality system certified to ISO 9001, with environmental and occupational health systems to match.
Specialists in this material
Our analysts work on platinum group metals, catalysts and coated membranes every day, for our own production. That is not a side-line service for us.
In the right place
Located in Gauteng in the OR Tambo SEZ, next to the country's largest airport — straightforward for both domestic and international sample logistics.
Getting started
How to send work to the laboratory.
Tell us what you need to know
Describe the material, the question you need answered, and any standard or contract the result has to satisfy.
We confirm method, turnaround and cost
We come back with the analytical approach, what it will cost and how long it will take, before anything ships.
Send the sample
We advise on sampling and packaging so the result reflects your material rather than your courier.
Receive a documented result
You get the result with its method and quality control record, in a form you can put in front of a counterparty.
Need an umpire assay, or a durability run?
Tell us the material and the question. We will confirm method, turnaround and cost before you ship anything.
