Sample submission

Sample disposal

After sample analysis, samples are retained at ALS free of charge for a limited time. After the free storage period has lapsed, sample can be returned, retained in paid storage, or disposed of by ALS as requested. The cost of disposal depends on many factors such as sample type and jurisdiction. Our client services team can provide a quotation for disposal prior to any actions being taken.

Quarantine

Some types of samples imported to certain regions (particularly Australia) require heat treatment and specific documentation. ALS is up to date with all importation requirements and permitting and will arrange for samples to clear customs and quarantine. Please contact ALS when sending samples between regions to receive the most current information and advice.

Submitting hazardous samples

A hazardous sample is defined as one that contains asbestos minerals, naturally occurring radioactive material (NORM), and/or high sulphide content. Please notify the receiving laboratory when submitting any of these sample types or others that could pose a health or safety risk to ensure the safety of staff handling them.

High sulphide samples

Pulverising a sample that is high in sulphides can accelerate the oxidation reaction of sulphides with air due to the higher surface area of the mineral available to react. This can result in high heat generation, and in extreme cases spontaneous combustion. It is therefore critical that the lab is notified when high sulphide samples are submitted for preparation so that precautionary measure can be taken.
