CHEMIST 1

DEFINITION: This is professional work in the detection, quantitation and characterization of chemical substances and materials in a base laboratory or mobile laboratory setting.

An employee in this job conducts, completes, evaluates and reports analytical laboratory tests that qualitatively and quantitatively identify chemical materials and substances. Work involves performing standardized tests to evaluate materials for the detection of substances for a variety of purposes. Testing procedures usually include the application of instrument analysis techniques to determine chemical composition. Test procedures are usually standardized but test results may vary widely and require professional interpretation and evaluation. Incorporation and assessment of quality assurance and quality control components are essential to the evaluation and validation of results produced. Work may include testifying in legal proceedings or Commonwealth courts about the tests conducted and the results obtained. Work is differentiated from the higher level by the responsibility for performing more standardized testing and the lack of responsibility for independently researching the development of new test methods and procedures. Work is reviewed for adherence to established testing procedures and methods by a professional supervisor or higher-level chemist through evaluation of laboratory reports and test results.

EXAMPLES OF WORK: Processes, prepares and analyzes water, soil, air, food commodities, tissues or waste samples for trace level organic or inorganic components or adulteration or contamination; standardizes solutions and prepares test reagents; and reports results.

Analyzes feeds, fertilizers or fish to determine the content of protein, nitrogen, fat, fiber and other elements and contaminants.

Performs analyses using chemical, physical or instrumental techniques.

Identifies and quantifies radiochemical species in water or in other sample matrices.

Performs chemical and physical analyses of plants, cements, paper, soap, textiles, oils and a variety of other materials for conformance with specifications or other quality standards and requirements.

Analyzes biological fluids, tissues, milk and food for biochemical constituents such as lipids, enzymes, proteins, carbohydrates, electrolytes and similar compounds, including toxic substances.

Testifies as a witness in Commonwealth courts or at hearings, as required.

Prepares reports and maintains records of work performed.

Provides training to staff on national quality assurance standards and monitors and assists in implementing quality assurance components.

Performs statistical calculations including determination of detection limit.

Identifies instrument malfunctions and assay control problems.

In a mobile laboratory environment, uses mobile instrumentation to analyze and report on locally collected samples and operates mobile analytical unit vehicles  to travel to test sites.

Assists in the implementation of new methods and procedures or the conduct of special projects.

Performs related work as required.

REQUIRED KNOWLEDGES, SKILLS, AND ABILITIES: Knowledge of the principles and practices of chemistry, particularly those involving standardized analytical techniques.

Knowledge of modern chemical laboratory methods, equipment and materials.

Knowledge of laboratory safety.

Knowledge of reference sources of information and current literature in the field of analytical chemistry.

Knowledge of quality assurance and quality control principles and practices.

Ability to perform standard laboratory operations using safety equipment.
