1. Introduction to the Theory and Practice of Sampling (TOS) – a new didactics for science, technology, industry, commerce and society.

Course provider: Kim H. Esbensen, KHE Consulting, Denmark

When: Sunday May 30th; Sky bar workshop room. Lunch, drinks and snacks is included in the short course package. 

This short course starts from level zero in a novel didactic framework without excessive mathematics and statistics, developing a conceptual framework with which TOS’ six Governing Principles and four Sampling Unit Operations can be understood in a unifying manner, enabling everybody to start sampling in a correct fashion in just one day.

The short course covers sampling from stationary lots, from moving, dynamic lots (process sampling) and focuses on sampling in the analytical laboratory as well, making use of many practical examples and cases

Attendees are offered a special bonus: selected topics/chapters from the 2021 follow-up book: “TOS & PAT – the way forward for representative process analytical sampling”. 

“Sampling is not gambling” (Pierre Gy). Analytical results forming the basis for decision making in science, technology, industry, society, commerce must be relevant, valid and reliable. But analytical results cannot be detached from the specific conditions under which they originate. Proper sampling emerges as the critical success factor before analysis.

This short course deals with how to acquire defensible representative samples from heterogeneous materials and lots and for optimal monitoring/QC in industrial processing & manufacturing. The sampling process must be in full compliance with the Theory and Practice of Sampling (TOS)the world’s only science-backed guarantee against hidden economic lossespreparing for valid decision making.

2. Grade Control in Underground Gold Operations.

Course providers: Dr. Simon Dominy

When: Monday May 31st, Radisson Blu Caledonien Hotel. Lunch, drinks and snacks is included in the short course package. 

This workshop will provide attendees with knowledge and critical understanding of underground sampling methods. It has been designed for anyone involved with the design, implementation and monitoring of an underground grade control programme. The presenter will make extensive use of case studies from Australia, South America and Europe. Participants will be encouraged to discuss their own mine grade control approaches. Whilst targeted at underground gold mine grade control, much of the course content will be applicable to any commodity. 

Attendees will learn about: 

  • Grade control versus ore control; 
  • Importance and value of good sampling; 
  • Applied ‘Theory of Sampling’ and notion of representativity; 
  • Relative pros and cons of different sampling methods; 
  • How to sample correctly in an underground environment; 
  • Sampling QAQC and error determination; 
  • Designing and implementing grade control systems.

3. Process Analytical Technology (PAT) and TOS-compliant sampling in Pharmaceutical production and monitoring - the rules of the game!

Course providers: Brad Swarbrick, Rodolfo Romañach and Kim H. Esbensen

When: Monday May 31st, Radisson Blu Caledonien Hotel - Sky bar workshop room. Lunch, drinks and snacks is included in the short course package. 

This short course presents the necessary and sufficient Theory and Practice of Sampling (TOS) principles and procedures for representative PAT sampling in pharmaceutical and biopharmaceutical operations in an easy-to-understand didactic format. Deliverables from this short course are:

  • TOS for process characterisation and improvement: variographic analysis,
  • How to estimate the total sampling-plus-analytical error effects, and how to decouple these from true process variation,
  • This course will show participants how to establish specifications for sampling of powder mixtures TOS focuses on counteracting the adverse effects of mixture heterogeneity. There is a complete duality between physical sample extraction and PAT sensor sampling: TOS is the missing link in PAT! 

It is often claimed that sampling in pharma necessitates special methods and precautions because of regulatory demands. Until recently authorities supplied a Draft Guidance for establishing blend uniformity in powder mixing processes. However this guidance was subsequently withdrawn and each company must currently justify their specifications. With the advent of Continuous Manufacturing (CM) the need for representative sampling in real time has greatly accelerated the innovation of new and reliable systems for collecting representative data using Process Analytical Technology (PAT). This approach must also be translated to batch processes, which are still the most used in industry today. There still exist many questions in industry such as: How can regulatory authorities assess disparate sampling procedures? or How can companies and supervisory management ensure adequate sampling? The Theory and Practice of Sampling (TOS) to the fore!

4. Variograms and their analysis for improved process knowledge.

Course provider: Dr Geoffrey Lyman, Principal, Materials Sampling & Consulting, Southport, Australia.

When: Sunday May 30th and Monday May 31st, Radisson Blu Caledonien Hotel. Lunch, drinks and snacks is included in the short course package for both days. 

Variograms are a powerful tool for process analysis and are critical to the design of sampling systems that must meet a target accuracy over the chosen period of sampling.  Variograms applied to data from mechanical sampling systems and on-line can also provide good estimates of the sampling or instrument precision.

Variograms can be estimated from data or from knowledge of process dynamics.  The Course will cover both aspects of estimation and will introduce the maximum likelihood method for variogram estimation that is unbiased and provides estimates of the variance of the variogram parameters; this is of great value in assessing the magnitude of the variogram nugget and determining when a process variogram has changed.

All aspects of variogram mathematics including variogram theory, models and estimation will be covered and methods of simulating data sets with target variograms described and implemented with available software.

Course attendees are encouraged to provide data from their operations for analysis in the second workshop day of the Course, using specialised software from Materials Sampling & Consulting.  Your laptops should be set up to permit installation of the software, but clean laptops will be available for rental at your expense, with prior arrangement.  MS Office Excel with Windows 10 will be required.  Data provided prior to the Course will be analysed.

Copies of the new textbook, Theory and Practice of Particulate Sampling, an Engineering Approach will be available for purchase at a discount as will the software packages for data analysis.  Further detail on the Course can be found at materials-sampling-and-consulting.com.

In case company-PC cannot be used to install the course software, a PC can be loaned for a charge of 120Euros/day. Please contact us to book one: contact@wcsb.com

5. Sampling Theory and Practice, their Economic Impact (Day 1) and Analysis of Sampling Correctness and the Futility of Bias Tests (Day 2).

Course providers: D. Francois-Bongarcon (AGORATEK International Consultants Inc., Canada) & Francis F. Pitard (Francis Pitard Sampling Consultants, LLC)

When: Sunday May 30th and Monday May 31st, Radisson Blu Caledonien Hotel. Lunch, drinks and snacks is included in the short course package for both days. 

Often coined ‘an eye opener’, this compound course is an in-depth introduction to all things sampling, including differences w.r.t. geostatistics, and theoretical origins as well as practical applications of Gy’s Theory of Sampling (TOS). For metallurgical accounting there is no substitute for sampling correctness, the cornerstone of TOS. Stationary cutters and many sampling devices heavily promoted by some well-known manufacturers are transgressing the most elementary rules of sampling correctness, therefore cannot and will not work. A profound analysis of these problems is presented.

Sampling is a difficult, at times economically dangerous job, and its contributions and limitations must be well understood. What to do and what not to do in front of a sampling challenge are fundamental to the economic success of a mining operation/decision. Alas, not every situation is always as per the books. The sampling practitioner must therefore learn to rely on good scientific knowledge, proper insight and perfect reflexes, which this course will start developing. Quantifying a sampling bias is an exercise in futility. Many people think that if they can quantify the sampling bias, they then can decide if they can live with the bias or not. Unfortunately, sampling biases are never constant; furthermore, an incorrect sampling system is likely to be biased in several independent ways. This important topic is vastly overlooked and will be discussed.
