Nature of Work
Under general supervision, performs professional work at the basic full-performance
level testing and analyzing raw, natural and processed substances using prescribed
chemical and physical laboratory procedures in order to determine chemical
composition or deviation from standards. Changes in procedures or standards
are usually accompanied by specific instructions. Work is reviewed by a
higher level chemist or supervisor through observation of skill and technique
and evaluation of analyses and findings. May be exposed to hazardous or unknown
substances. Assignments may include air and/or water pollution analysis,
construction materials or environmental health. Performs related work as
required.
Distinguishing Characteristics
May be distinguished by bench testing predominantly non organic substances.
Procedures are typically standardized and routine. Work is characterized
by the routine nature of the testing.
Examples of Work
Performs standardized laboratory and field sampling and test procedures
on substances requiring wet chemical and instrumental analysis.
Analyzes water samples of PH and various natural and pollutant components.
Collects and analyzes air samples for volatile organic pollutants; analyzes
samples qualitatively and quantitatively by gas chromatography, mass spectrometry
and associated techniques.
Sets-up, maintains and operates air and water quality monitor ing instruments.
Calibrates analysis equipment by following standard laboratory procedures.
Analyzes cement samples of compliance with construction standards.
Operates a variety of standard chemical laboratory equipment, such as spectrophotometer,
atomic absorption photometer, pH meter, gas chromatograph and extractors.
Records and reports the results of analyses.
