The quality and accuracy of an analysis depends on how the sample is collected in the process. Pierre Gy (founder of the Theory of Sampling) said: “At primary sampling, biases can be up to 1,000%, up to 50% at secondary sampling, while they almost never exceed 0.1 to 1% at analysis”.

his is why ITECA has been offering for more than 40 years complete sampling, sample preparation and sample transport, as well as centralized laboratories in accordance with international sampling standards and Theory of Sampling (TOS). When such high levels of representativeness are not required, our sample-takers are perfectly suitable for mineral industry processes.
