Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds....

-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. Similarly, it is nearly impossible to generalize the duties of chem techs, so greatly varied are their job descriptions.
Chemical or biochemical technicians often work in clinical (medical) laboratories conducting routine analyses of medical samples
Sample (material)
In general, a sample is a limited quantity of something which is intended to be similar to and represent a larger amount of that thing. The things could be countable objects such as individual items available as units for sale, or a material not countable as individual items. Samples of countable...

. Industries which employ chem techs include chemical, petrochemical
Petrochemical
Petrochemicals are chemical products derived from petroleum. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as corn or sugar cane....

Manufacturing
Manufacturing is the use of machines, tools and labor to produce goods for use or sale. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale...

Duties

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

Chemical technicians

The most common work done by chemical technicians is in R & D

Laboratory
A laboratory is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. The title of laboratory is also used for certain other facilities where the processes or equipment used are similar to those in scientific laboratories...

 environment, under the supervision of a chemist
Chemist
A chemist is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties such as density and acidity. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms...

 or a chemical engineer
Chemical engineer
In the field of engineering, a chemical engineer is the profession in which one works principally in the chemical industry to convert basic raw materials into a variety of products, and deals with the design and operation of plants and equipment to perform such work...

. They may typically assist in setting up and conducting chemical experiment
Experiment
An experiment is a methodical procedure carried out with the goal of verifying, falsifying, or establishing the validity of a hypothesis. Experiments vary greatly in their goal and scale, but always rely on repeatable procedure and logical analysis of the results...

s, 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.

Chemical technologists

Chemical technologists are more likely than technicians to participate in the actual design of experiments, and may be involved in the interpretation of experiental data. They may also be responsible for the operation of chemical process
Chemical process
In a "scientific" sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur by itself or be caused by somebody. Such a chemical process commonly involves a chemical reaction of some sort...

Qualifications

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.

National certification
Certification
Certification refers to the confirmation of certain characteristics of an object, person, or organization. This confirmation is often, but not always, provided by some form of external review, education, assessment, or audit...
