Particle Size Measurements pp Cite as. Particulate materials are often produced in very large quantities. In contrast, usually small quantities are used for characterization or applications. There are two reasons that small samples often give poor representation of the average quality of the bulk. One reason is the discrete nature of particles.

Practical applications of sampling theory. Minkkinen lut. It is also an error generating process where each step generates its own error component. The errors may be random or systematic. When the overall reliability of an analytical determination is estimated the variances squared errors of the individual error generating steps of the whole analytical process are additive and, consequently, the weakest link in practice determines the overall quality of the result.
Sampling and the probable error components generated by doing it cannot be neglected, therefore, when optimal analytical strategy for a given determination is considered. The optimum analytical strategy, and the error components to be considered, depend on the purpose of the determination, i. The aim of chemometric methods is to interpret chemical and analytical data. Therefore, the reliability of chemometrics also depends on the quality on analytical results — and ultimately on the quality of sampling An advanced sampling theory for analytical purposes has been developed by Pierre Gy [1, 2, 3], but is not very well known yet by analytical chemist and chemical metrologists.
Too often sampling plans are made without the help of the sampling theory. This concerns both industrial and process analytical problems and large national campaigns, when, e. By using sampling theory it often possible to cut down the assay cost and to improve the reliability of the results.

The technology was principally developed to count blood cells quickly by measuring the changes in electrical conductance as cells suspended in a conductive fluid passed through a small orifice. In the past seventy-five years, the technology has also been used to characterize thousands of different industrial particulate materials.
Developments in Geomathematics 4: Sampling of Particulate Materials: Theory and Practice reviews the theory and practice of sampling particulate solids, such as ores and concentrates. With examples borrowed from the mining, metallurgical, and cement industries, the book examines particulate materials of vegetable and mineral origin, including cereals, oil seeds, sugar beets, granulated drosses or slags, bars, plates, and ingots. Organized into nine parts encompassing 34 chapters, this volume begins with an overview of the theory of sampling and sampling-error generating mechanisms.

Ore and waste must be defined effectively to ensure an economically optimized mill feed in all mining operations. Grade control is essential for efficient mine operation, with key performance indicators including: effective definition of ore and waste and marginal ore if required ; correct delivery of ore and waste to their designated destination; optimized feed grade to the mill; minimal dilution; and maximum recovery. The process of grade control, broadly comprises data collection e.
(C) At each preparation stage, the (total) preparation error EZ is the sum of five independent errors: 1. (1) Error EZ1: loss of particles belonging to the sample. 2.

Gy's sampling theory is a theory about the sampling of materials, developed by Pierre Gy from the s to beginning s  in articles and books including:. The abbreviation "TOS" is also used to denote Gy's sampling theory. Gy's sampling theory uses a model in which the sample taking is represented by independent Bernoulli trials for every particle in the parent population from which the sample is drawn. The two possible outcomes of each Bernoulli trial are: 1 the particle is selected and 2 the particle is not selected. The probability of selecting a particle may be different during each Bernoulli trial.
In a discussion of sampling it is useful to distinguish two forms of solids , monolithic and particulate, as well as liquids and gases and to treat each material type as a separate category.
