Book Description
Excerpt from The Testing of Chemical Reagents for Purity The necessity of obtaining the highest degree of purity in those reagents which are most largely used in chemical analysis and research, demands a means of speedily recognizing the impurities most often encountered. This means of recognition, together with much general information regarding the various reagents, is afforded in a very comprehensive form by Dr. Krauchs' valuable work, which we present for the first time in English, the translation being that of the third German edition. We have practically adhered to the general arrangement and treatment adopted by the author. We would particularly call the attention of the reader to the fact that, in most instances, reference has been made to English abstracts from the original communications. We have also endeavoured to enhance the value of the book by substituting for the numerous references to German text books on chemical analysis the corresponding English works. We have to acknowledge the valuable aid given by the author himself in supplying us with additions and corrections, the result of his experience since the third German edition was published. The Latin titles of the reagents are those of the Pharmacop a Germanica and have been retained, as they may be of service for the recognition of certain chemicals in price lists. In conducting the various tests, the author emphasises rigid adherence to the degree of concentration, the amount of reagent used and the manner in which the test is to be carried out. Temperatures are, in all cases, given in degrees Centigrade. Finally, our thanks are due to those friends who have assisted us in revising the proofs of this translation.

Book Description
The American Chemical Society (ACS) Committee on Analytical Reagents sets the specifications for most chemicals used in analytical testing. Currently, the ACS is the only organization in the world that sets requirements and develops validated methods for determining the purity of reagent chemicals. These specifications have also become the de facto standards for chemicals used in many high-purity applications. Publications and organizations that set specifications or promulgate analytical testing methods-such as the United States Pharmacopeia and the U.S. Environmental Protection Agency-specify that ACS reagent-grade purity be used in their test procedures. The Eleventh Edition incorporates the "supplements" accumulated over the past eight years, removes some obsolete test methods, improves instructions for many existing ones, and also introduces some new methods. Overall, the safety, accuracy, or ease of use in specifications for about 70 of the 430 listed reagents has been improved, and seven new reagents have been added.

Book Description
Now in its fifth edition, the book has been updated to include more detailed descriptions of new or more commonly used techniques since the last edition as well as remove those that are no longer used, procedures which have been developed recently, ionization constants (pKa values) and also more detail about the trivial names of compounds.In addition to having two general chapters on purification procedures, this book provides details of the physical properties and purification procedures, taken from literature, of a very extensive number of organic, inorganic and biochemical compounds which are commercially available. This is the only complete source that covers the purification of laboratory chemicals that are commercially available in this manner and format.* Complete update of this valuable, well-known reference* Provides purification procedures of commercially available chemicals and biochemicals* Includes an extremely useful compilation of ionisation constants
