Chemical Technician

Problem Type 3 Given is a mass in grams and unknown is an amount in moles. 

When you are given the mass of one substance and asked to calculate the amount in moles of another substance in the chemical reaction, the general plan is 

Solving any reaction stoichiometry problem requires the use of a mole ratio to convert from moles or grams of one substance in a reaction to moles or grams of another substance. A mole ratio is a conversion factor that relates the amounts in moles of any two substances involved in a chemical reaction. This information is obtained directly from the balanced chemical equation. Consider, for example, the chemical equation for the electrolysis of melted aluminum oxide to produce aluminum and oxygen.

The Government and Industrial Professionals Directorate is expanding its activities and recently published a Short Course Catalog listing institutions that offer short courses in the polymer area. This Directorate also is working closely with the new ACS Division of Chemical Technicians. 

The determination of quantity in complex mixtures is also vital in health care and medicine. We are all familiar with the medical examinations in which a sample of blood or urine is sent to a laboratory for analysis. The procedures used have been developed by chemists, and are performed by trained chemical technicians. The high level of automation achieved by the chemists who designed these analytical procedures has greatly reduced the costs of such analyses. Clinical analysis continues to be driven by a need for better methods to detect and measure important proteins, for example, that while present in tiny amounts are relevant to our health and well-being. 

In the laboratory density is one of the most important characteristics that we have to describe various substances. It is also one of the most important tasks that a chemical technician performs. For example, to confirm the identity of an incoming raw material one of the tests technicians may perform is density. Is it sodium chloride or magnesium sulfate or sucrose ... 

The authors are thankful for the able assistance of the chemical technicians Warren Biest, Sue Opfer, William Andrews, and Fred Strauser. Also, the TGA work of David Chan and Joe Bulock, TPR runs by Claire Schosser, spectroscopy studies by John Freeman, XRD studies by Frank Hay and economic analysis by Jim Allman are greatly appreciated. 

So, two thoughts. One is, if colleges want to form better links to historically underrepresented student bodies, they would do well to take a look at their local community colleges to see who can move over. Companies can look in that direction because somebody who has come through two years of chemistry is certainly well qualified to be a chemical technician. Parry Norling fed me this idea, although he did not know it.

Preliminary data from a second workplace survey, the National Occupational Exposure Survey (NOES), conducted by NIOSH from 1980 to 1983, indicated that 1,957 workers, including 272 women, were potentially exposed to 1,1-dichloroethane in the workplace in 1980 (NIOSH 1984). The exposed workers were employed in the chemical and allied products and business service industries, as chemical technicians plumbers, pipefitters, and steamfitters supervisors in production occupations electricians machinists chemical engineers and welders and cutters. The estimates were based on direct observation by the surveyor of the actual use of the compound (100%). 

Chemical and glassware storage, dish washing, sample refrigerators, glassware dryers, autoclaves for the preparation of sterile sample bottles for the plant, computer(s) for assay calculations, water baths, fume hoods, etc., are additional basic equipment items needed. Typical overall space requirements are 450 ft of floor space per working chemical technician. 

Some industrial wastes result because it is cheaper to buy new material than to reclaim the used material. Some catalysts fall in this category. The 1996 American Chemical Society National Chemical Technician Award went to a technician at Eastman Chemical who set up a program for recovering cobalt, copper, and nickel from spent catalysts for use by the steel industry.194 This process for avoiding landfill disposal gave Eastman significant savings.

The scope of this book is designed to meet the needs of chemical operatives who are preparing for the examinations for the ordinary and advanced certificates in chemical plant operation, and for those taking chemical technician courses. It will also be of value to all those involved in chemical manufacture, particularly supervisors and maintenance staff. 

Nicergoiine is an ergot derivative used to treat symptoms of mental deterioration associated with cerebrovascular insufficiency as well as in peripheral vascular disease. Fumagalli et al. (1992) reported an airborne dermatitis on the face of a chemical technician who had been exposed to powders containing this drug and its chemical intermediates during their production. 

A case of occupational dermatitis was reported in a chemical technician, with no cross reactivity to pyridine derivatives. 

In 1921 Electrochemistry was taught for the first time to the Chemical Technicians and Metallurgists. The professional studies in Metallurgical Chemistry were opened in 1967. Electrochemistry, Corrosion, and Metal Protection are included, the latter subject as an elective. During this year, Electrochemistry was included in the Chemistry program.

In summary of the worldwide CWS administrative experience, it can be said that every overseas branch of the CWS surveyed found some means of creating a service that accorded with the concepts held by Fries and Porter. The lot of the chemical technician in what was supposed to be a technician s war was not an easy one, but the chemical technician managed to do what he was called on to do by dint of much improvisation and ingenuity.
