As TLC is less time consuming, low cost, and can be performed with less complicated technique it has a wide application in pharmaceutical analysis.

Concepts in Biochemical Pharmacology pp Cite as. As more potent drugs are used in ever decreasing dosage, studies of drug metabolism require analytical and separatory methods of increasing sensitivity. This demand has led to the development of powerful new techniques such as gas chromatography coupled to mass spectrometry.

Viva Voce. No, most organic compounds obtained from natural sources and synthesised in laboratories are not pure. Various methods are used for the purification of organic compounds that are based on the nature of the compound and the impurity present in it. Among the various separation techniques, chromatography is one of the most important separation technique extensively used to separate mixtures into their components and the purification of the compounds. The word chromatography originated from two greek words 'chroma' meaning 'colour' and 'graphine' meaning 'to write'. Chromatography means colour writing and it was first employed by a Russian scientist Mikhail Tsvet.

This book discusses the practical approach in the application of paper and thin layer chromatography techniques in the biological sciences. Organized into 18 chapters, this edition begins with an overview of the clinical aspects related to the detection of those metabolic diseases that can result in serious illness presenting in infancy and early childhood. This text then discusses the three major types of screening for inherited metabolic disorders in which paper or thin-layer chromatography are being used, including screening the healthy newborn population, screening the sick hospitalized child, and screening mentally retarded patients. Other chapters consider the procedures for thin layer chromatography. This book discusses as well the complexity of amino acid mixtures present in natural products.

Chromatography is a useful technique to precisely separate, analyze, and purify a wide range of samples, including food, pharmaceuticals, pesticides, air and water samples, and tissue extracts. You would have seen the separation of different coloured compounds using the simple paper chromatographic separation technique in your school laboratory.

Ясно, конечно, что это никакой не полицейский, это Клиент с большой буквы.  - Дайте мне угадать: наш номер вам дал приятель. Сказал, чтобы вы обязательно нам позвонили. Я прав.

Крикливый, тучный, мерзкий немец! - Клушар заморгал, стараясь переменить положение, и, не обращая внимания на боль, продолжал: - Ну чистая скотина, килограмм сто двадцать, не меньше. Он вцепился в эту красотку так, словно боялся, что она сбежит, - и я бы ее отлично понял. Ей-ей.
