Chemical technologists and technicians are workers who provide technical support or services in chemical-related fields. They may work under direct supervision or may work independently, depending on their specific position and duties. Their work environments differ widely, and include but are not limited to laboratories and industrial settings. As such, it is nearly impossible to generalize the duties of chem techs as their individual jobs vary greatly.
Chemical technologists are more likely than technicians to participate in the actual design of experiments, and may be involved in the interpretation of experimental data. They may also be responsible for the operation of chemical processes in large plants, and may even assist chemical engineers in the design of the same. Some post-secondary education is generally required to be either a chemical technician or technologist. 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 with scientist of a higher source.
Chemical or biochemical technicians often work in clinical (medical) laboratories conducting routine analyses of medical samples. Industries which employ chem techs include chemical, The most common work done by chemical technicians is in R&D. They generally work in a clean laboratory environment under the supervision of a chemist or a chemical engineer. They may typically assist in setting up and conducting chemical experiments, and may operate lab equipment under supervision. They are expected to maintain established quality control standards. 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.
