    The learner-centric instructional system of IGNOU

    The chemists occupy positions in different capacities in industry and national laboratories. The list of industries is very large; a few to name are Fertilizers, Sugar and Confectionery, Food Processing, Paints, Plastics and Polymers, Detergents, Glass and Ceramics, Cement, Dyes and Textiles, Pharmaceuticals, Petroleum Refining & Petrochemicals, Steel and Alloys, etc. Apart from the above, chemists are employed in many national laboratories run by CSIR, ICAR, etc.

    2

Post Graduate Diploma in Analytical Chemistry (PGDAC) is a continuing education

    programme designed and developed keeping in view the role of chemists played directly and indirectly in industry and national laboratories.

    2.1 Background of the Programme

    Seen against the demanding situation in which a chemist in an industry finds himself/herself, the training given through B.Sc. or in some cases even through M.Sc. curriculum is quite inadequate. While formulating a continuing education programme like PGDAC, adequate care and attention has been taken with respect to the of varied skill requirements such as practical work, problem tackling, information and quantitative skills, etc. The programme design was carried out systematically by holding an explorative workshop involving expertise from industry, academic institutions, professional/chartered bodies and Federation of industry. A thread bare discussion lead to the broad structure of the PGDAC programme. 2.2 Objectives of the Programme

    The objectives of this programme are:

To provide training in modern analytical techniques to the learners.

     To provide appropriate theoretical background and develop practical skills for analysing

    materials even in trace amounts using modern analytical methods and instruments. To enable students acquire the analytical data and interpret the same using statistical

    principles.

     To inculcate a problem solving approach by coordinating different analytical techniques. 2.3 Programme Structure

    This Diploma programme is worth 32 credits and is spread over eight courses. Out of eight,

    4 are theory courses of 6 credits each and 4 lab courses of 2 credits each. The basic structure of the programme is as given below.

    s/he may be permitted to stretch it over a period of another 2 years. In case the student is unable to pass all the courses of PGDAC programme in 3 years, the student may be permitted

    to stretch it for another one year. In such cases, the student has to seek readmission as per the „Re-admission‟ rules and pay the requisite fee. Please refer to Form No. 5 for further

    information on Re-admission. The fee paid at the time of initial admission is valid for 3 years.

    You may contact the Regional Centre for further information about the same. But, you are advised to pass all the courses successfully in 3 years.

    2.5 Medium of Instruction

    The medium of instruction is English only. The course material is also printed in English. 2.6 Fee Structure

    At present the programme fee for PGDAC is Rs. 7,000/-. As and when it is necessary, the University can revise the programme fee, therefore, please refer to the Student Handbook

    and Prospectus of your academic session for recent information related to fee.

    As stated above there are four theory and four laboratory courses in this programme which are worth six and two credits respectively. In this section a brief introduction of each of the course is given which gives an insight of the course. A list of units belonging to different blocks is given for an overall perception of the course.

MCH-001 BASIC ANALYTICAL CHEMISTRY CREDITS: 6

    This is the first course of Analytical Chemistry programme and addresses to the basics of Analytical techniques in the first few units. The first unit gives a general perspective of the analytical chemistry on the whole. The second and third units are devoted to concepts like accuracy, precision types of measurements and evaluation of analytical data. Unit 4 deals with Sampling- the most important initial step crucial for any analytical measurement. As a chemical laboratory is prone to a number of hazards, a practicing chemist needs to and must adhere to the laboratory safety norms. The Unit 5 addresses the safety aspect of the laboratory in requisite details so that the learners are equipped with the information required for the safety of their own as well as the fellow workers in the laboratory. Sixth Unit deals with an introduction to the instruments used for analytical measurements as the modern means of analysis are instrument based.

    The rest of the course from seventh unit onwards deals with a number of conventional analytical techniques. These include kinetic methods, neutralisation titrations, redox titrations, complexometric titrations, precipitation titrations and the gravimetric analysis.

     CREDITS: 6

    7

    This course is introduced to give you a reasonable understanding in the major techniques of electroanalytical methods, thermal methods and radioanalytical methods. In this course we will cover the basic theory, the practical aspects and scope of all individual techniques of these three categories. In electroanalytical techniques we use one or more electrical properties under controlled condition to obtain qualitative and quantitative information of a sample. These techniques can be divided into several classes depending on which aspects of the electrochemical cell are controlled and which are measured. You may be familiar with some of the electroanalytical techniques like potentiometry. In this course along with these

    techniques we will also introduce few new electroanalytical techniques like coulometry and

    voltametry. All these electroanalytical techniques will be discussed in Blocks 1, 2 and 3.

Similar to electrical properties, in thermal methods we study changes in the physical and

    chemical properties of a sample while it is undergoing heating process. We are also focusing on three important thermal techniques, that is, thermo gravimetric analysis (TGA),

    differential thermal analysis (DTA) and differential scanning calorimetry (DSC). There

    techniques are discussed in Block 4. In last block of this course, i.e. Block 5, you will study radioanalytical methods which are unique with regard to theoretical principles involved, handling of radioisotopes, and instrumentation.

    This course also has an integrated laboratory component which is titled „Electroanalytical and Other Methods Lab‟ having a code MCHL – 004. The list of experiments covered in it is

    given in Section 4.

    Laboratory courses are an integral component of any science programme. Analytical Chemistry being an experimental science, a laboratory component has been integrated with each of the theory courses. As mentioned earlier, the Post Graduate Diploma in Analytical Chemistry programme has a 25% component of the laboratory work. There are four

    laboratory courses for this programme. These courses are worth 2 credits each. Each of these

    laboratory course will require full-time presence of the student at the laboratory for one week

    or seven days continuously. During this time a student has to work for around 60 hours. Of this, 40 hours would be spent on experimental work and the remaining time will be used for doing calculations, preparations of records, viewing or listening to the video/audio programmes.
