Laboratory report preparation introduction

Laboratory Manual (0-321-81377-4) Prepared by John B. Vincent and Erica Livingston, both of the University of Alabama. This manual contains 29 experiments with a focus on real-world applications. Each experiment contains a set of pre-laboratory questions, an introduction, a step-by-step procedure (including safety information), and a report section featuring post-laboratory questions. Additional features include a section on laboratory safety rules, an overview on general techniques and equipment, and a detailed tutorial on graphing data in Excel. 

The conventional analytical process is comprised of sampling — sample preparation —> analysis —> calculation —> approval of results — report — decision.93 The introduction of productivity measurements to focus attention on continuous improvement and improving the reliability of assays to eliminate re-analysis can aid in re-engineering the process for greater efficiency.93 Automation is another important aspect of improving efficiency.94 The rate-limiting steps in many industrial laboratories, however, may precede or... 

As described in the introduction of this article, sample preparation procedures for off-site laboratories for the CWC have been developed and tested in international interlaboratory comparison (round-robin) tests (1 5), in two trial proficiency tests, and in over (14> official proficiency tests (see Chapter 6). Tables 2 and 3 list the types of samples in these tests. The first three tests were arranged mainly for purposes of method development, the fourth and fifth also for testing and validating of methods. The reports describing these tests (the round-robin books) contain a thorough description of how each of the participating laboratories prepared their samples (1 5). Most often, water samples (16 times), organic liquid samples (14 times), or soil samples (12 times) were used as... 

The first synthesis reported by Merrifield produced the desired tetrapeptide (Leu-Ala-Gly-Val).f l Amino acids, dipeptides, and tripeptides were all detected in the crude product released from the resin. Through continued improvements of the method, the high speed of the amino acid incorporation and automation, the solid-phase peptide synthetic methodology has become the method of choice for most laboratories synthesizing peptides. Shortly after the introduction of the solid-phase procedure it was used to synthesize insulin. This impressive achievement awakened the biochemical community to the promise of synthetic chemistry and initiated a period in which large numbers of peptide analogues were prepared and analyzed. 

The particular value of mechanical data-processing equipment and of computers in the rapid performance of statistical calculations based on laboratory data has been discussed (Section 3.3.4), as has their contribution to easing the burden of collecting data from measuring instruments, the performing of repetitive calculations, and the preparation of reports for laboratory work (Section 5.5). This section will consider the few examples that at present provide objective evidence for improvements in the reliability of laboratory work attributable to the introduction of modern data-processing equipment.

Henderson, Introduction to PMM, Technical Report. 715582-5, Ohio State University Electroscience Laboratory, Department of Electrical Engineering, prepared under contract No. F33615-83-C-1013 for the Air Force Avionics Laboratory, Wright Aeronautical Laboratories, Air Force Systems Command, Wright-Patterson Air Force Base, OH, February 1986. 

A considerable number of triarylethylene type estrogens have been prepared in the laboratories of the Richardson, Merrell Company. One of the earliest hypoHpidemic compounds reported in this series was Mer. 13 (XXXIV). When added to the diet of cholesterol-fed cockerels, compound XXXIV inhibited the development of hypercholesterolemia, as well as aortic and coronary atherosclerosis [131]. Interestingly enough, introduction of a dimethylaminomethylene group in trianisylethylene afforded the drug myordil, (Win. 5494, XXXV),... 

This set of experiments can be easily completed within four sessions of a 3h laboratory period, or it can be an extended laboratory that would include more independent research. We suggest having the students work in pairs, and the work plan along with the division of tasks should be clearly laid out by the team in a prelaboratory session. We also suggest that the students download the manuscript template from the Inorganic Chemistry iaamzl website for the preparation of their reports. The list of questions contains ideas to incorporate into the introduction and the discussion of results. 

In addition to those described in the references given above, numerous methods for the preparation of the reagents have been reported for hydroxylamine (e.g. Semon, 1923) and its O-methyl and O-ethyl derivatives (Jones and Oesper, 1914 Traube et al, 1920 Andrews et al., 1946). All of the reagents for effecting oximation are now commercially available (Pierce Chemical Co., Kodak Ltd, Applied Science Laboratories Inc., for example) and it is expected that others will appear on the market in due course. The recent introduction of the O-pentafluorobenzyl hydroxylamine, for example, offers advantages when electron-capture detection is required (Koshy et al, 1975 Nambova et al., 1975).
