           Trains and supervises staff in extraction techniques, analysis of blood and body fluids and consumables by mass spectral systems, infrared analysis and liquid chromatography to isolate, identify and quantitate toxic substances; and reviews data and report summaries to arrive at scientific conclusions.

           Evaluates and validates scientific mass spectral systems for the analysis of chemical and biological specimens; identifies long range laboratory needs and purchases scientific equipment to achieve agency goals; and implements new forensic testing methods.

           Conducts chemical, microscopic, toxicological and mass spectral analyses on chemical and biological evidence seized in connection with criminal investigations.

           Performs detailed physical and chemical analysis of evidence from tampering and contamination cases and documents findings. Preserves evidence and maintains chain of custody in criminal investigations.

           Testifies in court as a subject matter expert in toxicology and mass spectral analysis; and communicates routinely with law enforcement officials, Police Standards and Training, and the Chief Medical Examiner’s Office on issues related to DWI enforcement.




Skill: Requires skill in developing formats and procedures for special applications OR in investigating and reviewing the use of equipment and data for a specialized function.


Knowledge: Requires logical or scientific expertise to resolve problems of a specialized or professional nature in a wide range of applications.


Impact: Requires responsibility for achieving major aspects of long-range agency objectives by planning short- and long-term organizational goals, reviewing recommendations for procedural changes, and developing or revising program policies. Errors at this level result in incorrect decisions at an administrative level, and are detected subsequent to implementation in an overall evaluation process.


Supervision: Requires direct supervision of other employees doing related or similar work, including scheduling work, recommending leave, reviewing work for accuracy, performance appraisal, or interviewing applicants for position vacancies.


Working Conditions: Requires performing regular job functions in an environment which includes exposure to continuous physical elements or a number of disagreeable working conditions with frequent exposure to minor injuries or health hazards.


Physical Demands: Requires light work, including continuous walking or operating simple equipment for extended periods of time as well as occasional strenuous activities such as reaching or bending.


Communication: Requires reviewing summaries and reports and making decisions to solve problems or to achieve work objectives as well as articulating and expressing those solutions and goals. This level also requires formal presentations of solutions and goals to employees and the general public to increase the responsiveness of the agency toward the demands of its client system.


Complexity: Requires evaluating a combination of wide-ranging job functions to determine work procedures, to solve problems, and to reach conclusions by applying analytical, technical, or scientific thinking. This level also requires planning policies and long-term strategies, drawing conclusions based on available criteria, and evaluating the effectiveness of program objectives.


Independent Action: Requires independent judgment in planning and evaluating work procedures and in supervising the development of professional, technical and managerial standards under administrative direction and according to broad departmental guidelines.




Education: Master’s degree from a recognized college or university with major study in toxicology, chemistry, biochemistry, the biological sciences, forensic science, the health sciences, the health professions, medical technology, the physical sciences, or a related scientific field dependent on the needs of the position. Additional years of approved formal education may be substituted for up to one (1) year of required work experience on a one-to-one basis. Professional certification in chemistry or toxicology by an approved accrediting agency may be substituted for one of the required years of experience.


Experience: Four years’ experience performing toxicological analysis specific to the needs of the position, such as analysis by gas chromatography/mass spectrometry or analysis of biological materials for toxic substances, one year of which shall have been at a supervisory level. Each additional year of approved work experience may be substituted for one year of required formal education at the graduate level only.


License/Certification: Must be eligible to hold a New Hampshire driver’s license and have access to transportation for use in statewide travel. Applicants must meet certification requirements as a Technical Supervisor per the Health Care Financing Administration for Clinical Laboratory Personnel according to the Clinical Laboratory Improvement Amendments of 1988 (CLIA).

2. Visual deficiencies must not interfere with ability to perform laboratory analyses. Physical condition must allow for

the administration of vaccines and/or necessary diagnostic tests. Superior manual dexterity and coordination

required. Must be able to operate, maintain, and troubleshoot lab instrumentation such as gas chromatograph,

high performance liquid chromatograph, and mass spectrometer, gamma or liquid scintillation counter.


3. Must be willing and able to handle unpleasant and/or hazardous specimens such as feces, sputum, blood,

vomitus, urine, animal heads, and samples known to contain infectious organisms and/or toxic chemicals such as

carcinogens and asbestos. Must be willing to undergo tests or immunization for communicable diseases

periodically as necessary, to include the Hepatitis B vaccine.


4. Excellent oral and written communication skills are required.


5. Must work flexible hours when required.


RECOMMENDED WORK TRAITS: Knowledge of the principles, practices and application of toxicology. Knowledge of the principles and practices of quantitative and qualitative organic and inorganic chemistry. Knowledge of chemical and physical laboratory equipment and material. Knowledge of the principles of physics and practices of physical testing. Knowledge of college level mathematics. Knowledge of the application of chemical, biological and physical sciences. Knowledge of risk assessment models associated with exposure to toxic and hazardous substances. Skill in evaluating and analyzing scientific toxicology data. Skill in the use and care of laboratory equipment and materials. Ability to interpret data from computer sources and familiarity with computer systems. Ability to testify in criminal and civil court is required. Ability to communicate effectively both orally and in writing. Ability to report the results of laboratory tests, clearly and concisely, orally and in writing.
