Shipment Samples

The analysis for these samples are run in triplicate, and are usually preceded by trial runs utilizing two separate and independent methods of analyses to verify adequacy of the method used and to attain prescribed level confidence in the result. Sampling originating / delivered by Surveyors. Traders and Commercial establishments including third party assays are assumed to be classified as Shipment samples.

Sample Preparations

As a routine practice OMLI crushes the entire sample to minus 3 mesh, mechanically splits the sample, and pulverizes a sample split to at least minus 150 mesh. As routine practice we will automatically use cleaner sand between each sample at no cost to the customer.
