Occasionally, a company may be willing to provide a high school graduate with training to become a chemical technician, but more often, a two-year degree will be required. Chemical technologists generally require completion of a specific college program—either two year or four year— in chemical, biochemical, or chemical engineering technology or a closely related discipline. They usually work under or with a scientist such as a

Technicians

Chemical or biochemical technicians often work in clinical (medical) laboratories conducting routine analyses of medical samples such as blood and urine. Industries which employ chem techs include

Duties

As a general rule, chemical technologists are more likely to be provided with greater autonomy and more complex responsibilities than chemical technicians.

They may also compile records for analytical studies, and sometimes are involved in writing reports on studies. National certification for chemical technologists and technicians is required in some countries.
