Full Title:Analytical Science
Module Code:INST S7Z02
Credits: 7.5
Valid From:Semester 1 - 2019/20 ( June 2019 )
Module Delivered in 9 programme(s)
Module Description:The aims of this module are to: introduce students to selected aspects of modern chemical and biochemical analytical instrumentation and techniques; increase students' confidence in undertaking analysis (independently and in a team) and in designing and executing experiments; encourage students to take careful measurements to assess the validity of their results.
Learning Outcomes:
On successful completion of this module the learner should be able to
  1. Describe the fundamental theoretical basis of some chromatographic and spectroscopic including their applications and limitations.
  2. Compare and contrast common analytical techniques in separation science (GC and HPLC) and spectroscopy (Atomic and Molecular).
  3. Demonstrate proficiency in using a range of analytical instrumentation and techniques by following standard operating procedures.
  4. Combine technical skills and theoretical knowledge to define a problem in analytical science and select the most suitable technique to solve the problem.
  5. Assess the validity of analytical procedures and assays with reference to the ICH Harmonised Tripartite Guidelines on assay validation.

Module Content & Assessment

Indicative Content
Introduction and general principles of chromatography, modes including Adsorption, Partition, Ion Exchange and Size Exclusion. Focus on gas liquid chromatography, including instrumentation, mobile/stationary phase selection, packed/capillary columns, detectors (FID, MS), applications and associated problems. Focus on HPLC; overview of HPLC, normal/reverse phase, column/mobile phase selection, diode-array detection and applications. Comparison of GC and HPLC. Chromatographic Parameters; Efficiency defined mathematically, Resolution defined and its dependence on chromatographic parameters will be illustrated for optimisation of resolution.
Molecular Spectroscopy
The electromagnetic spectrum, absorption of UV/visible radiation, excitation of electrons, relationship of structure to absorption, Beer-Lambert Law. The range of colorimeters and spectrophotometers and a survey of the main components parts. Applications of UV and visible spectroscopy and quantitative calculations.
Atomic Spectroscopy
Principle of absorption of energy by ground state atoms in gaseous state, electronic transitions, absorption/emission. Flame-based analytical systems; instrumentation, processes involved and examples of applications. Plasma-based techniques (ICP); comparison with flame-based techniques. Spectral, molecular, ionization and physical interferences. Quantitative techniques (including standard addition, internal standard). Application of atomic spectroscopy for sustainable environmental monitoring.
Validation of Analytical Procedures/Assays
Focus on ICH (International Conference on Harmonisation) Harmonised Tripartite Guidelines on assay validation, validation characteristics; accuracy, precision, specificity, detection limit, quantitation limit, linearity, range will be defined and equations will be used in practice to validate data obtained by students during laboratory practicals and (where available).
Learning and Teaching Methods
Teaching methods will comprise delivery of lectures and practical sessions with an emphasis on deep learning in a student-centred learning. A variety of blended and eLearning techniques will be deployed including in-class demonstrations, classroom assessment techniques, problem-based learning, peer assisted learning, self assessment and use of multi-media (animations, videos, eAssessments).
Virtual Learning Environment
The DkIT Virtual Learning Environment (Moodle) page for Analytical Science will be used extensively as a repository for lecture material, past exam papers, video links, online resource links, online quizzes, feedback, peer-reviewed articles as well as documents pertaining to practical lab sessions (Material Safety Data Sheets).
Virtual Laboratory Experiments
The use of virtual laboratory experiments in chromatography, spectroscopy and immobilisation reaction systems will complement laboratory practical sessions and reinforce fundamental theoretical concepts (for example; students will gain access to a CHROMacademy account managed by lecturer for full access to chromatography database, including HPLC, GC and hyphenated techniques, eLabs, assessments, webcasts, tutorials, lab simulations/ tools, peer-reviewed technical articles and application notes. Certification by CHROMacademy is also available to students upon completion of assessments).
Laboratory Practical Sessions
The following list is designed to serve as an illustration of possible practical exercises which would illustrate key concepts and techniques: • Separation of pigments by thin layer chromatography, • Use of gas liquid chromatography to identify and quantify components in a mixture, • Use of internal and external standards in gas liquid chromatography for quantification, • Use of high performance liquid chromatography to detect and quantify selected analytes, • To assess column quality in HPLC separations, • To verify Beer-Lambert Law in UV-Vis spectroscopy, • To study absorption of visible light by compounds and their absorption spectra, • To study practical aspects of spectroscopy including accuracy, precision, sources of error and procedure validation, • To determine metal content by atomic absorption spectrophotometry using the standard addition method, • To determine metal content by flame photometry using an internal standard.
