Course content

Sampling and sample preparatin is a cornerstone in performing sound experiments, and thus essential to any kind of analytical chemistry project: the results obtained will never be better than the samples injected.

The course starts with a throughout treatment of Pierre Gy’s Theory of Sampling (TOS), which tells how to obtain a representative sample without systematic errors and with an acceptable uncertainty.  Based on TOS the practice and tools for taking the samples and reduce the sample mass in a representative way is treated.  All common matrices, soil, water and air, are addressed.

The last part of the course covers the sample preparation techniques for extraction, purification and pre-concentration of samples for injection into modern analytical instruments such as GC and, HPLC. The preparation part includes active and passive sampling for gases (adsorbents, denuders, traps, filtering etc.), liquid, solid and headspace sampling for liquids (LLE, SPE, SPME SBSE SLE etc.) and liquid and headspace sampling from solids (shake, MW, US, PLE, SFE, etc.). The sample preparation part focus on organic analytes only.

The theory is supplemented with computer simulations, laboratory experiments, excursions and expert guest-lectures of selected topics.

Learning outcome

This course enables the student to plan and perform sampling and sample preparation, including sampling strategy, determination of number of samples and sample size, sample selection, sampling techniques and tools, and methods for sample preparation for organic analytes, extraction, filtering, purification and pre-concentration including advanced methods like SPME, SBSE, PLE, SLE for common instrumental analytical methods.

Knowledge:

Describe the theory and principles for representative sampling according to Gy’s Theory of Sampling. Describe the theory for active and passive sampling. Describe the tools, instruments, and techniques for sample preparation of organic analytes.

Skills:

Plan sampling experiments and analyse the results in terms of sampling variance using Anova and variographic analysis. Predict sampling variance using Gy’s formula for simple matrices. Plan sample preparation for organic analytes, including selection of tools and techniques.

Competences:

Plan and perform sampling pilot experiments and real sampling for chemical analysis. Develop and apply sample preparation methods for instrumental analysis of organic compounds. Evaluate and discuss the scientific literature within sampling and sample preparation.

Recommended prerequisites

The course LKEF10076 Analytical Chemistry or equivalent is a requirement. Knowledge of basic statistics is also recommended.
