Principles of Flow Techniques
Abstract. The lecture will start with brief description of ways of automation applied on different levels and with different types of analysers. Then, basic principles of flow techniques, namely continuous/segmented flow analysis as equilibrium-based techniques and flow/sequential injection analysis as nonequilibrium-based techniques will be described in detail, and compared with respect to flow system set-up, sample manipulation, sample throughput, repeatability, advantages/disadvantages in terms of green chemistry approaches, etc. Miniaturization of flow injection and sequential injection systems will be stressed out. Experiments carried out in case of determination using spectrophotometry, fluorometry, or colour reaction will be demonstrated in short videos. Possibilities of automation using low-pressure flow techniques, application in different areas including sample preparation before separation of analytes in different systems, typically liquid chromatography (LC), and monitoring of long-term processes will be presented as well.

Bead Injection as a tool for online solid phase extraction
Sequential Injection Analysis is a flexible and programmable platform for executing various analytical tasks in a flow. The key features are high precision, automation, miniaturization, operation speed, and long-term durability. These enable the development of methods for sample pretreatment, direct determination, or online hyphenation of multiple analytical instruments.
Online Solid Phase Extraction can be automated by Sequential Injection Analysis using either reusable commercial or lab-made cartridge columns or automatically disposable columns (Bead Injection). The extraction utilizes a broad choice of commercial or experimental sorbents (silica, polymer, polysaccharide, or diatomaceous earth) in a particulate, monolith, or nanofibrous morphology.
Sequential Injection Analysis significantly accelerates method development by continual online detection of the column outlet, which enables understanding of critical parameters during the sample loading, matrix elimination, and analyte elution, maximizing the method recovery and minimizing time and consumable demands.

Automation of liquid phase extractions using modern flow techniques
Abstract. Sample preparation is a key step in the analytical process that decides on sensitivity, reliability, and selectivity of the analytical method. Above all, sample compatibility with the instrumental technique aimed for analyte quantification must be achieved. Sample preparation can also be a major source of error to the result, e.g., by contaminating the sample during treatment. Procedural automation and coupling sample preparation directly to the intended detection instrument can reduce these risks and generally comes with a gain in cost and time efficiency, as well as reproducibility and reliability of analysis. Most often today, versatile autosampler systems are used for this purpose, while flow techniques can show interesting advantages or add positive features to such processing instrumentation. Thus, getting familiar with the concepts and potential of handling samples in flow for analyte preconcentration and matrix clean-up can be more than just useful background knowledge for the analytical chemist.
In this seminar, the possibilities of the automation of liquid phase (micro)extraction (LPE/LPME) procedures using modern flow approaches/techniques should be presented for which a short overview of the different LP(M)E approaches should be given, including specific challenges and a comparison to solid phase extraction as alternative sample preparation. Furthermore, the potential, characteristics, and differences in operation and performance of flow approaches should be given focusing to Sequential Injection Analysis and the Flow Batch technique Lab-In-Syringe, a technical approach that overlaps with autosampler automation.
To this end, examples will be shown on implementation modes, system setup, and possibilities of operation. Moreover, an overview of challenges in coupling automated sample preparation to modern instrumental analysis should be given.

Point-of-care analysis refers to diagnostic testing or analysis conducted near the patient, often at the bedside or in a clinical setting, rather than sending samples to a centralized laboratory for processing. This approach offers several advantages: Rapid Results, Improved Patient Outcomes, Convenience, Cost-Efficiency, Accessibility, Streamlined Workflow. However, there are also some limitations and considerations associated with point-of-care analysis. "ASSURED" is an acronym that was developed by the World Health Organization (WHO) to outline the ideal characteristics of diagnostic tests for use in resource-limited settings. Each letter in "ASSURED" stands for a key attribute that such tests should possess:
Affordable,
Sensitive,
Specific,
User-friendly,
Rapid and robust,
Equipment-free or minimal equipment requirements
Deliverable to those who need it.
Paper or other cellulose materials seems to be an ideal starting point for developing such analytical systems. The paper appears to be a very good material for manufacturing point-of-care analytical systems. Lecture attendees will learn both the basics of lab-on-paper systems operation (lecture no.1) as well as the current state of knowledge on this topic prepared based on literature data (lecture no.2).

Arduino-based analytical systems - the principles with examples
Do-it-yourself electronics in chemical analysis - some examples through the eyes of a non-expert
Technological development is inevitable. From the Volta cell, through the invention of transistors and integrated circuits, we found ourselves in the digital age. All smaller and larger discoveries have contributed to the formation of chemical laboratories as we know them today - computerized, full of affordable electronics. There is a high probability that in the laboratories that emphasize mechanization and/or automation of analytical processes, there are systems based on microcontroller boards, especially Arduino. During the meeting, a descriptive explanation will be made of what Arduino actually is, where its popularity comes from (after all, it is one among many other microcontroller boards) and what applications it may have in analytical chemistry (Arduino-based analytical systems - the principles with examples). It is also worth looking at the use of such a microcontroller board through the eyes of a chemist and showing how to build basic electronic systems useful in a chemical laboratory in a simple and cheap way (Do-it-yourself electronics in chemical analysis - some examples through the eyes of a non-expert).

Capillary electrophoresis based glycomics – introduction
Glycomics is a scientific discipline, which is focused on the exploration, characterization and study all of the carbohydrate structures. For this end, capillary electrophoresis (CE) is one of the most frequently used techniques, having outstanding advantages over liquid chromatography as ultra-high resolution and very low amount of sample need, among others. In this presentation, we will discuss the theoretical basics as practical aspects, with special attention on the CE based N-glycan structure elucidation. We will also shed light on how CE based glycomics can be used for biomarker research as well on its role in the characterization of biologics and biosimilars.
