Processing Chemicals – Outsourced Manufacturer Analytical Capabilities Important

When you required an outsourced manufacturer for processing your chemicals for your various product lines, it is important that they have exceptional analytical capabilities. You want a well-rounded chemical manufacturer that has the capability to grow with you, particularly when you are trying to develop a new product or improve an existing one.

Typical Equipment a Contractor Should Have

Equipment for involved gas chromatography is essential. Chromatography, in bare bones, is the separation of mixtures; therefore, when it refers to gases, you are dealing with possible volatile components such as solvents and monomers. Typical applications of gas chromatography include separating different components in a mixture or even testing the purity of a material. In some cases, this process can also identify the ingredients in an unknown chemical compound or mixture.

Facilities for reversed phase high performance liquid chromatography (HPLC) are important too. This process is a type of column chromatography which involves the purification of individual compounds from mixtures and can be used for dealing with comparative scales.

Yet another type of chromatography should be considered an absolute must in your quest for a contractor with outstanding analytical capabilities. It is called size exclusion chromatography. This process helps determine the molecular weight of different polymers. These polymers, often used in plastics, are connected by covalent chemical bonds.

Fourier transform infrared spectroscopy is another facet you should confirm when shopping around for a manufacturing contractor. This type of spectroscopy is a measurement method by which arrays of particles are accumulated based on specific measurements based on the property of waves from a radiation-based source.

Manual and automatic titrations are yet another important analytical talent the manufacturer's laboratory should have. Titration is a common technique of quantitative analysis in which the concentration of a recognised reactant is determined. This method is also called volumetric analysis because measurements of volume are involved.

Partnerships

The chemical contractor's ability to forge partnerships with other analytical laboratories for third-party testing and substantiability is important too. Look for these collaborations as they can provide an even larger range of analytical services you may eventually need. Not every chemical manufacturer's lab has 100% of testing mechanisms and equipment it needs to perform every test imaginable. That is why partnerships with other expert laboratories in important. The bottom line is that you need an effective contract manufacturer for your product line and that means the equipment and resources to process and analyse your chemicals.

HPLC in Enzymatic Analysis $325 The use of High Performance Liquid Chromatography (HPLC) techniques in the study of enzymatic reactions has grown significantly since the publication of the first edition of this highly successful book: the role of enzymes in biological research has expanded; the application of HPLC and enzymes has extended to more disciplines; advances in separation techniques and instrumentation have increased the capability of HPLC; and the discovery of new enzymes has spawned new methods of analysis. High Performance Liquid Chromatography in Enzymatic Analysis, Second Edition addresses these developments in its coverage of the refinements of HPLC methods and their use in a wide range of laboratory applications. It offers the same practical approach found in the first edition, incorporates a wealth of new information into existing chapters, and adds new chapters to deal with new applications, including capillary electrophoresis, forensic chemistry, microdialysis, and the polymerase chain reaction. Topics include: * Application of HPLC to the assay of enzymatic activities * Concepts and principles of HPLC, including the latest technological advances * Concepts and principles of capillary electrophoresis (CE) * Strategy for design of an HPLC/CE system for assay of enzyme activity * Preparation of enzymatic activities from tissues and single cells * Analysis of enzymatic activities in body fluids, including chromatobiosis * HPLC for the identification of new enzymatic activities * Fundamentals of the polymerase chain reaction * HPLC in forensics * Survey of enzymatic activities assayed by the HPLC method, including many new categories * Multienzyme systems, including many new examples * HPLC in the analysis of contaminated food "It is the ability of HPLC to accomplish separations completely and rapidly that led to its original application to problems in the life sciences, particularly those related to purification. An analysis of the literature revealed that this technique was used primarily for the purification of small molecules, macromolecules such as peptides and proteins, and more recently, antibodies. This application to purification has all but dominated the use of the method, and there has been a plethora of books, symposia, and conferences on the use of HPLC for these purposes. However, it was only a matter of time before others began to look beyond and to explore the possibilities that result from the capacity to make separations quickly and efficiently." --from the preface to the First Edition Easy to read and full of practical advice and hundreds of diagrams and examples, High Performance Liquid Chromatography in Enzymatic Analysis, Second Edition is an invaluable resource for students, researchers, and laboratory workers in analytical chemistry and biochemistry, molecular biology and cell biology, and for anyone interested in keeping up with this fast-growing field.
